REV. 1.0.0 8/13/03 PRODUCT SPECIFICATION TMC2192 Pin Definitions (continued) Pin Name Pin Number Value Description PXCK 95 TTL Pixel Clock Input. PXCK is a clock signal that period is twice the sample rate of the pixel data. The operating range is 20 to 30 MHz. The clock is internally divided by 2 to generate the internal pixel clock, PCK. PXCK drives the entire TMC2192 except the asynchronous microprocessor interface. RESET 94 TTL Master Chip Reset. When LOW, All outputs are tri-stated and the internal state machines and control registers are reset. At rising edge of RESET, all outputs are active, the preset values will be loaded into the control registers and the internal states machines start to operate. VSIN 55 TTL Vertical Sync Input. When operating in slave, Genlock, or DRS-Lock the TMC2192 will start a new vertical field with each falling edge of VSIN that is coincident with HSIN. SYNC & CONTROL OUTPUTS (11 pins) FLD[2:0] 81–83 TTL Field Identifier. Field Identifier outputs the current field number. For all video standards the field identifier will cycle through the eight counts. HSOUT 74 TTL Horizontal Sync Output. The alignment of HSOUT to the pixel data port or DCVBS port is controlled by control register TSOUT. 76–80 TTL Vertical Blanking Interval Line Identifier. LINE identifies the current line number for the first 31 lines. If the line count is greater than 31 then LINE is 11111b. The first line with a vertical serration is considered to be line 0. 73 TTL Pixel Data Control. LINE[4:0] PDC When PDCDIR = LOW: At a rising edge, The next pixel starts a controlled ramp of the PD data. At a falling edge, the pixel prior is the last PD used in the ramp. The rising edge is determined by the PDCCNT control register, the falling edge of PDC is determined by the horizontal timing registers. When PDCDIR = HIGH: PDCIN is used to override the internal PDC. When HIGH, the internal PDC controls the blank and unblank window. When LOW, the video remains blanked regardless of the internal PDC. All edges have the same ramp control as the internal PDC. VSOUT 75 TTL Vertical Sync Output. The alignment of VSOUT to the pixel data port or DCVBS port is controlled by control register TSOUT.

For slave and genlock modes the falling edge of HSIN must be LOW prior to the CB data in order to demux the data correctly. For master mode synchronization the falling edge of HSOUT must be LOW prior to the Y data in order to demux the data correctly. Finally, in 656 mode the demuxing of the data stream is determined by the TRS codes, the first sample after the TRS is considered a CB sample of the CB Y CR YI packet. Input Formats Control Registers for this section Address Bit(s) Name 0x05 7 D1OFF 0x05 6-4 INMODE 0x06 0 TSOUT The control register D1OFF controls the formatting of the incoming luminance data at the pixel data port. When D1OFF is HIGH a blanking level of 6410 is subtracted from the luminance and when D1OFF is LOW the incoming the pixel data is passed through. The inversion of the MSB’s on the CB and CR components is controlled by the INMODE control register. The TMC2192 supports YCBCR component sources on the pixel data port. YCBCR input sources are supported in 10 bit 4:2:2, 20 bit 4:2:2, 20 bit 4:4:4, and 24 bit 4:4:4. In the 4:2:2 cases the color difference components are linearly interpolated to 4:4:4 internally.

Blanking of selected lines is determined by the v bit of the TRS. However the control registers VBIENx can override and blank the active video portion of VBI lines regardless of the state of the v-bit. 0x06 0 TSOUT Genlock Control Registers for this section The TMC2192 offers a variety of synchronization modes; these are master, slave, genlock, 656 mode, and DRS-Lock. In master mode, the TMC2192 generates its own timing and the synchronization is supplied externally by HSOUT and VSOUT signals. In slave and genlock modes the TMC2192 derives its timing from the input pins HSIN, VSIN. In 656 mode the timing is driven by the synchronization codes embedded into the data stream. Master The TMC2192 drives the output pins HSOUT and VSOUT to synchronize the incoming video. A new color frame starts at the rising edge of RESET. The encoder always starts at the 1st vertical serration in field 8 and will freerun the field and line sequence. The control register bit SRESET can be used to synchronize the start of the field and line sequence in master mode by resetting the FVHGEN state machine. Output synchronization signal VSOUT can operate in a traditional sync mode or in a MPEG style field toggle mode. Slave The TMC2192 is driven by the input synchronization pins HSIN and VSIN. When the falling edge of HSIN and VSIN occurs at the same rising edge of PXCK the TMC2192 will start a new field.VSIN can be either a traditional pulse or the MPEG style field toggle. In both cases the TMC2192 will flywheel through fields 2, 4, 6, and 8 synchronizing only to fields 1, 3, 5, and 7. n = (SY+BR+BU+CBP+AV)*2 0 The TMC2192 is driven by the input synchronization pins HSIN and VSIN. When the falling edge of HSIN and VSIN occurs at the same rising edge of PXCK the TMC2192 will start a new field.VSIN can be either a traditional pulse or the MPEG style field toggle. In both cases the TMC2192 will flywheel through fields 2, 4, 6, and 8 synchronizing only to fields 1, 3, 5, and 7. The TMC2192 collects GRS data and resets its subcarrier phase and frequency to the data embedded in the GRS stream. The GRS detection occurs only on the CBVS port. DRS The TMC2192 is driven by the input synchronization pins HSIN and VSIN. When the falling edge of HSIN and VSIN occurs at the same rising edge of PXCK the TMC2192 will start a new field.VSIN can be either a traditional pulse or the MPEG style field toggle. In both cases the TMC2192 will flywheel through fields 2, 4, 6, and 8 synchronizing only to fields 1, 3, 5, and 7. Subcarrier phase adjustment is determined by the DRS data. The DRS detection can occur on either the CBVS port or the pixel data port. Propagation Delay The propagation delay from the pixel data (PD) input to the D/A output is 64 PXCK’s. Figure 8 shows the propagation delay for both master and slave synchronization modes. For CCIR656 data streams, pixel 736 (pixel 0 in Figure 8) is the midpoint of sync and is 32 PXCK’s (24 PXCK’s in PAL) after the EAV TRS. 63 128 65 PXCK PD[23:14] CBn Yn CRn Yn+1 CB0 Y0 HSIN tDO HSOUT (TSOUT = 1) DACx (ANALOG) tDO DCVBS (D[7:0],FLD[2:1]) COMP0 COMP1 65-6294-09 Midpoint of the Falling Edge of Sync Figure 7.

The mode of operation is determined by the PDCDIR control register. When PDC is an input the internally generated PDC is ANDed with the PDC pin. This allows the user to blank any active video regions. When PDC is an output, the internally generated PDC is the output for the PDC pin. Address Bit(s) Name 0x04 1-0 PDRM 0x06 2 PDCDIR 0x18 4-0 VBIENF1 0x19 4-0 VBIENF2 0x1F 7-0 PDCCNT The content of VBIENFx[4:0] selects the first line to contain an active video region in each field, all subsequent lines for the remainder of the field are active. To blank an entire field, the user zeroes the VBIENFx[4:0] control register. In CCIR656 slave mode, the user can selectively blank any enabled line by setting its TRS V bit HIGH. For 525-line systems, NTSC line numbering is employed, with the first vertical serration starting on line 4. PAL line numbering is used with 625-line systems, with each field's line 1 being the start of the first vertical serration. The internal PDC control will toggle to a logic HIGH at the pixel specified by PDCNT and toggle to a logic LOW four pixels prior to the end of the active video region. The starting point and ending point of the active video region (VA) are determined by the control registers 10h to 1Fh. When PDC is used as an input, the sloped edge of the active video region will occur on the next four pixels following the toggle point. Edge Shaping The TMC2192 has three modes of sloped edges on the active video region and are controlled by PDRM control register. Any line(s) enabled by the closed caption control are automatically unblanked for the closed caption waveform, irrespective of the corresponding values of VBIENF. Table 3.

The duration is expressed in PCK clock cycles. In this way, any pixel clock rate between 10 MHz and 15 MHz can be accommodated, and any desired standard or non-standard horizontal video timing may be produced. Horizontal timing parameters can be calculated as follows: t = N x ( PCK period ) = N x ( 2 x PXCK period ) where N is the value loaded into the appropriate timing register, and PCK is the pixel clock period. When programming horizontal timing, subtract 5 PCK periods from the calculated values of CBP and add 5 PCK periods to the calculated value for VA. The control register HALFEN enables the 1st half line (UBV) on line 283 for NTSC, PAL-M and line 23 for all other PAL standards when it is LOW. Table 4.

When setting the control register DDSRST is HIGH, the TMC2192 will reset the DDS to the SYSPH value on the next field 1, line 1 (line 4 for NTSC), pixel 1 occurrence and will reset this bit to be LOW. This allows the encoder to start with the correct SCH relationship. The phase of the subcarrier reference will drift over time since a 32 bit accumulator has a error of ±0.5 Hz when generating the subcarrier reference for NTSC 13.5 MHz. • Subcarrier Reset At the rising edge of RESET the DDS starts to generate the subcarrier reference and will reset the DDS to the SYSPH value every field 1, line 1 (line 4 for NTSC), pixel 1 occurrence. This enables the encoder to maintain the proper SCH relationship. • Genlock The Genlock mode allows the TMC2192 to lock to a composite reference when used in conjunction with the TMC22071A Genlocking Video Digitizer. The TMC22071A produces a genlock reference signal (GRS) which contains field identification, PALODD status, relative phase and relative frequency of the composite reference. The GRS is sampled on the CVBS bus 60 PXCK’s after the falling edge of HSIN. The phase and frequency values are used to update the DDS on a line to line basis, thus synchronizing the subcarrier to an external composite reference. • DRS-Lock the TMC22x5y. The TMC22x5y produces a decoder reference signal (DRS) which contains field identification, PALODD status, relative phase and relative frequency of the composite or S-video input. The DRS is sampled on either the CVBS bus or the PD port, depending on DRSSEL, 60 PXCK’s after the falling edge of HSIN. The phase and frequency values are used to update the DDS on a line to line basis, thus synchronizing the subcarrier to an external composite reference. • Ancillary Data Control (ANC) Subcarrier synchronization in ANC mode is covered in the Ancillary Data Control section of this data sheet. SCH Phase Error Correction SCH refers to the timing relationship between the 50% point of the leading edge of horizontal sync and the positive or negative zero-crossing of the color burst subcarrier reference. SCH error is usually expressed in degrees of subcarrier phase. In PAL, SCH is defined for line 1 of field 1, but since there is no color burst on line 1, SCH is usually measured at line 7 of field 1. The need to specify SCH relative to a particular line in PAL is due to the 25 Hz offset of PAL subcarrier frequency. Since NTSC has no such 25 Hz offset, SCH applies to all lines. The SCH relationship is important in the TMC2192 when two video sources are being combined or if the composite video output is externally combined with another video source. In these cases, improper SCH phasing will result in a noticeable horizontal jump of one image with respect to another and/or a change in hue proportional to the SCH error between the two sources. SCH phasing can be adjusted by modifying BURPH and SYSPH values by equal amounts. SCH is advanced/delayed by one degree by increasing/decreasing the value of BURPH and SYSPH by approximately B6h. An SCH error of 15o is corrected with SYSPH and BURPH offsets of AAAh. The DRS-Lock mode allows the TMC2192 to lock its composite output to the decoded composite or S-video input of 22 REV. 1.0.0 8/13/03 PRODUCT SPECIFICATION TMC2192 Burst Envelope 0 The TMC2192 includes the ability to adjust the burst amplitude and the shape of the burst. The Control Registers BRSTFULL, BRST1 and BRST2 hold the magnitude of the burst vector. BRSTFULL is the maximum amplitude of the burst vector. BRST1 and BRST2 determine the intermediate values of the burst vector for the burst envelope shaping. A 5 pixel burst envelope shaping occurs at the rising and falling edges of burst. At the rising edge of burst the next 5 pixels have the following weighting; BRSTFULL – BRST1, BRSTFULL – BRST2, BRSTFULL/2, BRST2, and BRST1. At the falling edge of burst the next 5 pixels have the following weighting; BRST1, BRST2, BRSTFULL/2, BRSTFULL – BRST2, and BRSTFULL – BRST1. With this flexibility the user determine the shape, amplitude and width of the burst signal. -20 -30 -40 -50 -60 65-6294-19 Attenuation (db) -10 -70 -80 0 0.1 0.2 0.3 0.4 0.5 Normalized Frequency (Pixel rate) Figure 16.

The color-difference low-pass filters on the TMC2192 establish chrominance bandwidths which meet the specifications outlined in CCIR Report 624-3, Table II, Item 2.6, for system I over a range of pixel rates from 12.27 Mpps to 14.75 Mpps. Equal bandwidth is established for both colordifference channels. Pedestal Enable The TMC2192 has the ability to independently select lines for pedestal insertion during the vertical blanking interval (VBI). For 525-line systems and using the NTSC line numbering convention, in which the first vertical serration is on line 4 for field 1 and line 266 for field 2, the vertical interval lines map to the control registers VBIPEDxy as shown in Table 15.

Likewise, enabling the pedestal on line 288 enables it for the remainder of field 2. Line Selection The line to contain CC data is selected by a combination of the CCFLD bit and the CCLINE bits. CCLINE is added to the offset shown in Table 16 to specify the line. Pedestal Height PEDHGT1 determines the height of the pedestal for the luminance channel on the composite path. The range of the pedestal height is from -22.1 to 21.74 IRE in .345 IRE increments. Table 13.

For NTSC and PAL-M formats the blank D/A code is 240 (295 mV) and the sync D/A code is 8 (9 mV). For all other PAL formats the blank D/A code is 256 (314 mV) and the sync D/A code is 12 (14 mV). In all cases the sync edges are sloped to insure the proper rise and fall times in all video standards. Closed Caption Insertion 625 Parity Generation Standard Closed-Caption signals employ ODD parity, which may be automatically generated by setting CCPAR HIGH. Alternatively, parity may be generated externally as part of the bytes to be transmitted, and, with CCPAR LOW, the entire 16 bits loaded into the CCDx registers will be sent unchanged. Control Registers for this section Operating Sequence Address Bit(s) Name 0x1C 7-6 CCD1 0x1D 1-0 CCD2 0x1E 7 CCON 0x1E 6 CCRTS 0x1E 5 CCPAR 0x1E 4 CCFLD 0x1E 3–0 CCLINE A typical operational sequence for closed-caption insertion on line xx is: Read Register 1E and check that bit 7 is LOW, indicating that the CCDx registers are ready to accept data. If ready, write two bytes of CC data into registers 1C and 1D. Write into register 1E the proper combination of CCFLD and CCLINE. CCPAR may be written as desired. Set CCRTS HIGH. The CC data is transmitted during the specified line. The TMC2192 includes a flexible closed-caption processor. It may be programmed to insert a closed caption signal on any line within a range of 16 lines on ODD and/or EVEN fields. Closed Caption insertion overrides all other configurations of the encoder: if it is specified on an active video line, it takes precedence over the video data and removes NTSC setup if setup has been programmed for the active video lines. Closed Caption is only available when the TMC2192 is in a 13.5 MHz pixel rate. As soon as CCDx s transferred into the CC processor (and CCRTS goes LOW), new data may be loaded into registers 1C and 1D. This allows the user to transmit CC data on several consecutive lines by loading data for line n+1 while data is being sent on line n. Closed caption is turned on by setting CCON HIGH. Whenever the encoder begins producing a line specified by CCFLD and CCLINE, it will insert a closed caption line in its place. If CCRTS is HIGH, the data contained in CCDx will be sent. IF CCRTS is LOW, Null bytes (hex 00 with ODD parity) will be sent. 24 REV. 1.0.0 8/13/03 PRODUCT SPECIFICATION TMC2192 Interpolation Filters x/Sin(x) Filter Each video output on the TMC2192 is digitally filtered with sharp-cutoff low-pass interpolation filters. These filters ensure that the frequency band above base-band video and below the pixel frequency (fS/4 to 3fS/4, where fS is the PXCK frequency) are sufficiently suppressed. Control Registers for this section Since these are fixed-coefficient digital filters, their filter characteristics depend upon clock rate.

Interpolation Filter – Passband Detail REV. 1.0.0 8/13/03 25 TMC2192 PRODUCT SPECIFICATION Analog outputs of the TMC2192 are driven by three 10 bit D/A converters, operating at twice the pixel rate. The outputs drive standard video levels into 37.5 or 75 Ohm loads. An internal voltage reference is used to provide reference current for the D/A converters. For more accurate levels, an external fixed or variable voltage reference source is accommodated. The video signal levels from the TMC2192 may be adjusted by varying the common Vref or the 3 independent Rrefs. Each video D/A converter has an independent reference resistor that can adjust the output gain. D/A Matching is achieved by trimming the each external reference resistor of each D/A. Digital Composite Output In addition, the TMC2192 supplies a 10 bit digital composite signal on pins D[7:0] and FLD[2:1]. The digital composite output can be either an interpolated signal on a non-interpolated signal, this controlled by the control register SEL_CLK.

P = odd parity bit, x = reserved bit will be ignored The first three words of ancillary data comprise the TRS signal (ANC2-0) which indicates the end of active video. Also known as the Ancillary data header, the TRS signal is a 00h, FFh, FFh sequence. Except for the TRS words, ancillary data bit 0 (B0, LSB) is odd parity for B7-1. The data type word (TT) is used to specify the ancillary data type. The TMC2192 compares this 7 bit value with the contents of the ANCID control register. If there is a match, the ancillary data will be processed. If there is no match, the TMC2192 ignores ancillary data. 26 The word count data (D11-0 in MM, LL) in the ancillary data packet indicate the number of words in ancillary data. Ancillary phase data is used to program the MSBs of the PHASE register. ANCPHEN and PHV determine how ancillary phase data is used. When ancillary data is not present, the TMC2192 assumes PHV = LOW.

The F bit is part of the EAV timing reference code and tracks the F0 bit. Operating Modes The field number bits (F2-0) from the ancillary data packet FIELD word, are used to program the encoder’s field counter depending upon the state of the synchronous video flag (SVF) and the ANCTREN bit in the control register. In the basic operating mode (ANCTREN = LOW), all timing is found in the F bit of EAV. F2-0 and SVF are ignored and the encoder subcarrier synthesizer is reset to the PHASE value every eight fields (when the field counter transitions from 111 (field 8) to 000 (field 1). In the basic mode, ANCFREN and ANCPHEN are typically set LOW, ignoring ancillary frequency and phase data. If ANCFREN and ANCPHEN are HIGH, the TMC2192 uses the incoming ancillary frequency and phase data on a lineby-line basis. REV. 1.0.0 8/13/03 In genlocking mode (ANCTREN and SVF = HIGH), the subcarrier synthesizer is allowed to free run, with phase and frequency being set from the ancillary data packet PH12-0 and FR31-0 data. The field counter increments just like it does in basic mode. Field sequence mode (ANCTREN = HIGH and SVF = LOW), is the same as basic mode except that the field counter is set by the F2-0 bits in the FIELD word of ancillary data. If ancillary data is not present on a line, the field counter will continue to count as it does in basic mode. When ancillary data is present, the contents of the field counter are loaded with field data (F2-0). In this way, the TMC2192 may be synchronized with an external source by sending field data only once. 27 TMC2192 PRODUCT SPECIFICATION Layering Engine Address Bit(s) Name Control Registers for this section 0x0A 7-0 DKEYMAX Name 0x0B 7-0 DKEYMIN 7-0 EKEYMAX Address Bit(s) 0x04 2 SKEN 0x0C 0x05 3-2 OMIX 0x0D 7-0 EKEYMIN 0x07 6 SKFLIP 0x0E 7-0 FKEYMAX 0x09 7 HKEN 0x0F 7-0 FKEYMIN 0x09 6 BUKEN 0x09 5 SKEXT 0x09 4 DKDIS 0x09 3 EKDIS 0x09 2 FKDIS 0x09 1-0 LAYMODE The TMC2192 features a robust layering engine with three possible input layers controlled by two keying controls. The layer assignments are shown in Table 22, along with the keying control. The keying controls, KEY pin or OL4-0 are aligned with the incoming pixel data stream and are then delayed throughout the chip to be continuously aligned with the input video streams.

Layering Engine Overlay Mixer The OL[4:0] bus provides the ability to overlay 30 different 24 bit values onto the pixel data path. The 24 bit overlay colors must be the same format as the incoming Pixel data. For Y,Cb,Cr input formats the range of Y values spans the entire range of the format, 1 to 254, this enables super whites and super blacks in the overlay palette. When OL[4:0] is equal to 00h the pixel data port to be the output of the overlay mixer. If OL[4:0] is in the range of 1 to 31 then the output source is one of 30 possible overlay col- 28 ors, see Table 22. Overlay Address Map. When OL4-0 equal to 16, the overlay mixer produces a pixel data output with half the luminance magnitude and chrominance magnitude. Any OL4-0 value greater than 16 will result in a overlay mix with a full amplitude overlay and the pixel data with half amplitude pixel data (PD) or half amplitude CVBS data as its values. This allows for transparent overlays or produce shadow boxes around overlaid text. The midpoint of the rising and falling edges on the mixed output is determined by the transition of the OL[4:0] pins in REV. 1.0.0 8/13/03 PRODUCT SPECIFICATION TMC2192 relation to the PD port.

Hardware Keying The KEY input switches the input to the Comp data path between the composite video generated from the PD port and the CVBS data bus on a pixel-by-pixel basis. This is a “soft” switch is executed over 3 PCK periods to minimize out-ofband transients. Keying is accomplished in the digital composite video domain. The coefficients for the mix are 0, 1/8, 1/2, 7/8, and 1 . The COMP output is the final output for all overlay functions. key value and a minimum key value. If the pixel data is greater than xKEYMIN and less than or equal to xKEYMAX, then a key match is signaled for that channel. xKEYMAX A B A<=B KEY MATCH xKEYMIN Hardware keying is enabled by the key Control Register HKEN. Normally, keying is only effective during the active video portion of the encoded video line (as determined by Control Register VA). That is, the horizontal blanking interval is generated by the encoder even if the KEY signal is held HIGH through horizontal blanking. However, it is possible to allow digital horizontal blanking to be passed through from the CVBS bus to the COMP output by setting key Control Register BUKEN HIGH. In this mode, KEY is always active, and may be exercised at will. The KEY input is registered into the encoder just as Pixel data is clocked into the PD port. It is internally pipelined, so the midpoint of the KEY transition occurs at the output of the pixel that was input at the same time at the KEY signal. Data Keying Data keying for each channel Y, Cb, and Cr, is separately enabled or disabled by the control registers DKEYDIS, EKEYDIS, and FKEYDIS.

Parallel Microprocessor Interface The parallel microprocessor interface is active when SER is HIGH and employs a 12-line interface; an 8 bit data bus and 2 bit address location, 1 bit read/write select, and a chip select controlling the timing. Two addresses are required for device programming, one to the pointer and one to the data location. When writing, the address is presented along with a LOW on the R/W pin during the falling edge of CS. Eight bits of data are presented on D7-0 during the subsequent rising edge of CS. 29 TMC2192 PRODUCT SPECIFICATION In read mode, the address is accompanied by a HIGH on the R/W pin during a falling edge of CS. The data output pins go to a low-impedance state tDOZ after CS falls. Valid data are present on D7-0 tDOM after the falling edge of CS. Because this port operates asynchronously with the pixel timing, there is an uncertainty in this data valid output delay of one PXCK period.

Either port alone can control the entire chip. Up to four TMC2192 devices may be connected to the 2-wire serial interface with each device having a unique address. The 2-wire interface comprises a clock (SCL) and a bi-directional data (SDA) pin. The encoder acts as a slave for receiving and transmitting data over the serial interface. When the serial interface is not active, the logic levels on SCL and SDA need to be pulled HIGH by external pull-up resistors. Data received or transmitted on the SDA line must be stable for the duration of the positive-going SCL pulse. Data on SDA must change only when SCL is LOW. If SDA changes state while SCL is HIGH, the serial interface interprets that action as a start or stop sequence. bit indicates the direction of data transfer, read from or write to the slave device. If the transmitted slave address matches the address of the device (set by the state of the SA1-0 input pins in Table 24), the TMC2192 acknowledges by bringing SDA LOW on the 9th SCL pulse. If the addresses do not match, the TMC2192 will not acknowledge. Table 21.

If the master device does not acknowledge the TMC2192 during a read sequence, the encoder interprets this as “end of data”. Start signal Slave address byte Block Pointer Offset Pointer Data byte to read or write Stop signal When the serial interface is inactive (SCL and SDA are HIGH) communications are initiated by sending a start signal. The start signal is a HIGH-to-LOW transition on SDA while SCL is HIGH. This signal alerts all slaved devices that a data transfer sequence is coming. The first eight bits of data transferred after a start signal comprise a seven bit slave address and a single R/W bit. The R/W Writing data to specific control registers of the TMC2192 requires that the 8 bit address of the control register of interest be written after the slave address has been established. This control register address is the base address for subsequent write operations. The base address auto increments by one for each byte of data written after the data byte intended for the base address.

Reading requires two data transfer operations: The base address must be written with the R/W bit of the slave address byte LOW to set up a sequential read operation. REV. 1.0.0 8/13/03 Reading (the R/W bit of the slave address byte HIGH) begins at the previously established base address. The address of the read register auto increments after each byte is transferred. To terminate a write sequence to the TMC2192, a stop signal must be sent. A stop signal comprises a LOW-to-HIGH transition of SDA while SCL is HIGH.

This is used to change the mode of communication (read, write) between the slave and master without releasing the serial interface lines. Bit 3 Bit 2 Bit 1 Bit 0 ACK SCL 65-6294-29 Figure 26.

Applications Discussion The suggested output reconstruction filter is shown in Figure 29. The phase and frequency response for the encoder and the reconstruction filter is shown in Figure 30. The circuit in Figure 31 shows the connection of power supply voltages, output reconstruction filters and the external voltage reference. All VDD pins should be connected to the same power source.

The reference voltage in Figure 31 is from an LM185 1.2 Volt band-gap reference. The suggested trim is designed to give ±10% of trim around 5K Ohms. This RREFx sets the "gain" for that D/A converter. Varying RREFx ±10% will cause the full-scale output voltage on the D/A to vary by ±10%. An alternative output reconstruction filter is the Microelectronic Modules Corp. ST-163E, which contains 4 independent reconstruction filter. The phase and frequency response of this filter is shown in the Output Low-Pass Filters Section of this data sheet. 63 TMC2192 Layout Considerations Designing with high-performance mixed-signal circuits demands printed circuits with ground planes. Wire-wrap is not an option. Overall system performance is strongly influenced by the board layout. Capacitive coupling from digital to analog circuits may result in poor picture quality. Consider the following suggestions when doing the layout: • • • 64 Keep analog traces (CBYPx, VREF, RREF, DACx) as short and far from all digital signals as possible. The TMC2192 should be located near the board edge, close to the analog output connectors. The power plane for the TMC2192 should be separate from that which supplies other digital circuitry. A single power plane should be used for all of the VDD pins. If the power supply for the TMC2192 is the same for the system's digital circuitry, power to the TMC2192 should be filtered with ferrite beads and 0.1µF capacitors to reduce noise. PRODUCT SPECIFICATION • Decoupling capacitors should be applied liberally to pins. For best results, use 0.1µF capacitors. Lead lengths should be minimized. Ceramic chip capacitors are the best choice. • If there is dedicated digital power plane, it should not overlap the TMC2192 footprint, the voltage reference, or the analog outputs. Capacitive coupling of digital power supply noise from this layer to the TMC2192 and its related analog circuitry can have an adverse effect on performance. • The PXCK should be handled carefully. Jitter and noise on this clock or its ground reference will translate to noise on the video outputs. Terminate the clock line carefully to eliminate overshoot and ringing. • Connect all unused inputs to the TMC2192 to either ground or VDD. Do not leave them unconnected. The ground plane should be solid, not cross-hatched. Connections to the ground plane should be very short.
