Copyright © 2008, Texas Instruments Incorporated TVP5150AM1-EP Ultralow-Power NTSC/PAL/SECAM Video Decoder SLES213 – MAY 2008 2 Introduction 2.1 Description www.ti.com The TVP5150AM1 device is an ultralow-power NTSC/PAL/SECAM video decoder. Available in a space-saving 32-terminal TQFP package, the TVP5150AM1 decoder converts NTSC, PAL, and SECAM video signals to 8-bit ITU-R BT.656 format. Discrete syncs are also available. The optimized architecture of the TVP5150AM1 decoder allows for ultralow power consumption. The decoder consumes 115 mW of power in typical operation and consumes less than 1 mW in power-down mode, considerably increasing battery life in portable applications. The decoder uses just one crystal for all supported standards. The TVP5150AM1 decoder can be programmed using an I2C serial interface. The decoder uses a 1.8-V supply for its analog and digital supplies and a 3.3-V supply for its I/O. The TVP5150AM1 decoder converts baseband analog video into digital YCbCr 4:2:2 component video. Composite and S-video inputs are supported. The TVP5150AM1 decoder includes one 9-bit analog-to-digital converter (ADC) with 2× sampling. Sampling is ITU-R BT.601 (27.0 MHz, generated from the 14.31818-MHz crystal or oscillator input) and is line locked. The output formats can be 8-bit 4:2:2 or 8-bit ITU-R BT.656 with embedded synchronization. The TVP5150AM1 decoder utilizes Texas Instruments patented technology for locking to weak, noisy, or unstable signals. A Genlock/real-time control (RTC) output is generated for synchronizing downstream video encoders. Complementary four-line adaptive comb filtering is available for both the luma and chroma data paths to reduce both cross-luma and cross-chroma artifacts; a chroma trap filter is also available. Video characteristics including hue, contrast, brightness, saturation, and sharpness may be programmed using the industry standard I2C serial interface. The TVP5150AM1 decoder generates synchronization, blanking, lock, and clock signals in addition to digital video outputs. The TVP5150AM1 decoder includes methods for advanced vertical blanking interval (VBI) data retrieval. The VBI data processor slices, parses, and performs error checking on teletext, closed caption, and other data in several formats. The TVP5150AM1 decoder detects copy-protected input signals according to the Macrovision™ standard and detects Type 1, 2, 3, and colorstripe pulses. The main blocks of the TVP5150AM1 decoder include: • Robust sync detector • ADC with analog processor • Y/C separation using four-line adaptive comb filter • Chrominance processor • Luminance processor • Video clock/timing processor and power-down control • Output formatter • I2C interface • VBI data processor • Macrovision detection for composite and S-video 8 Introduction Submit Documentation Feedback TVP5150AM1-EP Ultralow-Power NTSC/PAL/SECAM Video Decoder www.ti.com 2.2 SLES213 – MAY 2008 Applications The following is a partial list of suggested applications: • Digital televisions • PDAs • Notebook PCs • Cell phones • Video recorder/players • Internet appliances/web pads • Handheld games • Surveillance • Portable navigation 2.3 Trademarks TI and MicroStar Junior are trademarks of Texas Instruments.

The decoder supports a maximum input voltage range of 0.75 V; therefore, an attenuation of one-half is needed for most input signals with a peak-to-peak variation of 1.5 V. The maximum parallel termination before the input to the device is 75 Ω. See the application diagram in Figure 6-1 for the recommended configuration. The two analog input ports can be connected as follows: • Two selectable composite video inputs or • One S-video input An internal clamping circuit restores the ac-coupled video signal to a fixed dc level. The programmable gain amplifier (PGA) and the automatic gain control (AGC) circuit work together to make sure that the input signal is amplified sufficiently to ensure the proper input range for the ADC. The ADC has nine bits of resolution and runs at a maximum speed of 27 MHz. The clock input for the ADC comes from the PLL. 3.2 Composite Processing Block Diagram The composite processing block processes NTSC/PAL/SECAM signals into the YCbCr color space. Figure 3-1 shows the basic architecture of this processing block. Figure 3-1 shows the luminance/chrominance (Y/C) separation process in the TVP5150AM1 decoder. The composite video is multiplied by subcarrier signals in the quadrature modulator to generate the color difference signals Cb and Cr. Cb and Cr are then low pass (LP) filtered to achieve the desired bandwidth and to reduce crosstalk. An adaptive four-line comb filter separates CbCr from Y. Chroma is remodulated through another quadrature modulator and subtracted from the line-delayed composite video to generate luma. Contrast, brightness, hue, saturation, and sharpness (using the peaking filter) are programmable via I2C. The Y/C separation is bypassed for S-video input. For S-video, the remodulation path is disabled. 14 Functional Description Submit Documentation Feedback TVP5150AM1-EP Ultralow-Power NTSC/PAL/SECAM Video Decoder www.ti.com SLES213 – MAY 2008 Gain Factor Peak Detector Bandpass X Peaking Composite Delay Line Delay + Delay Y Y Quadrature Modulation Contrast Brightness Saturation Adjust SECAM Luma Cr Notch Filter Cb Composite SECAM Color Demodulation Cb Composite Quadrature Modulation Cr Color LPF ↓ 2 Cr Notch Filter Color LPF ↓ 2 Burst Accumulator (Cb) Cb 4-Line Adaptive Comb Filter LP Filter LP Filter Delay Delay Burst Accumulator (Cr) Figure 3-1. Composite Processing Block Diagram (Comb/Trap Filter Bypassed for SECAM) 3.3 Adaptive Comb Filtering The four-line comb filter can be selectively bypassed in the luma or chroma path. If the comb filter is bypassed in the luma path, chroma notch filters are used. TI's patented adaptive four-line comb filter algorithm reduces artifacts such as hanging dots at color boundaries and detects and properly handles false colors in high-frequency luminance images such as a multiburst pattern or circle pattern. 3.4 Color Low-Pass Filter In some applications, it is desirable to limit the Cb/Cr bandwidth to avoid crosstalk. This is especially true in case of video signals that have asymmetrical Cb/Cr sidebands. The color LP filters provided limit the bandwidth of the Cb/Cr signals. Color LP filters are needed when the comb filtering turns off, due to extreme color transitions in the input image. See Section 3.20.25, Chrominance Control #2 Register, for the response of these filters. The filters have three options that allow three different frequency responses based on the color frequency characteristics of the input video.

A line delay exists in this path to compensate for the line delay in the adaptive comb filter in the color processing chain. The luma information is then fed into the peaking circuit, which enhances the high frequency components of the signal, thus improving sharpness. 3.6 Chrominance Processing For NTSC/PAL formats, the color processing begins with a quadrature demodulator. The Cb/Cr signals then pass through the gain control stage for chroma saturation adjustment. An adaptive comb filter is applied to the demodulated signals to separate chrominance and eliminate cross-chrominance artifacts. An automatic color killer circuit is also included in this block. The color killer suppresses the chroma processing when the color burst of the video signal is weak or not present. The SECAM standard is similar to PAL except for the modulation of color, which is FM instead of QAM. 3.7 Timing Processor The timing processor is a combination of hardware and software running in the internal microprocessor that serves to control horizontal lock to the input sync pulse edge, AGC and offset adjustment in the analog front end, vertical sync detection, and Macrovision detection. 3.8 VBI Data Processor (VDP) The TVP5150AM1 VDP slices various data services such as teletext (WST, NABTS), closed caption (CC), wide screen signaling (WSS), etc. These services are acquired by programming the VDP to enable standards in the VBI. The results are stored in a FIFO and/or registers. The teletext results are stored only in a FIFO. Table 3-1 lists a summary of the types of VBI data supported according to the video standard. It supports ITU-R BT. 601 sampling for each. Table 3-1.

This is done through port address C3h. Each read from or write to this address auto increments an internal counter to the next RAM location. To access the VDP-CRAM, the line mode registers (D0h to FCh) must be programmed with FFh to avoid a conflict with the internal microprocessor and the VDP in both writing and reading. Full field mode also must be disabled. Available VBI lines are from line 6 to line 27 of both field 1 and field 2. Each line can be any VBI mode. Output data is available either through the VBI-FIFO (B0h) or through dedicated registers at 90h to AFh, both of which are available through the I2C port. 3.9 VBI FIFO and Ancillary Data in Video Stream Sliced VBI data can be output as ancillary data in the video stream in the ITU-R BT.656 mode. VBI data is output during the horizontal blanking period following the line from which the data was retrieved. Table 3-2 shows the header format and sequence of the ancillary data inserted into the video stream. This format is also used to store any VBI data into the FIFO. The size of FIFO is 512 bytes. Therefore, the FIFO can store up to 11 lines of teletext data with the NTSC NABTS standard. Table 3-2. Ancillary Data Format and Sequence BYTE NO.

A third signal (I2CSEL) is used for slave address selection. Although the I2C system can be multimastered, the TVP5150AM1 decoder functions only as a slave device. Both SDA and SCL must be connected to a positive supply voltage via a pullup resistor. When the bus is free, both lines are high. The slave address select terminal (I2CSEL) enables the use of two TVP5150AM1 decoders tied to the same I2C bus. At power up, the status of the I2CSEL is polled. Depending on the write and read addresses to be used for the TVP5150AM1 decoder, I2CSEL can either be pulled low or high through a resistor. This terminal is multiplexed with YOUT7 and hence must not be tied directly to ground or IO_DVDD. Table 3-6 summarizes the terminal functions of the I2C-mode host interface. Table 3-5. Write-Address Selection I2CSEL WRITE ADDRESS 0 B8h 1 BAh Table 3-6. I2C Terminal Description SIGNAL TYPE I2CSEL (YOUT7) I DESCRIPTION SCL I/O (open drain) Input/output clock line SDA I/O (open drain) Input/output data line Slave-address selection Data transfer rate on the bus is up to 400 kbit/s. The number of interfaces connected to the bus is dependent on the bus capacitance limit of 400 pF. The data on the SDA line must be stable during the high period of the SCL except for start and stop conditions. The high or low state of the data line can change ony with the clock signal on the SCL line being low. A high-to-low transition on the SDA line while the SCL is high indicates an I2C start condition. A low-to-high transition on the SDA line while the SCL is high indicates an I2C stop condition. Every byte placed on the SDA must be eight bits long. The number of bytes that can be transferred is unrestricted. Each byte must be followed by an acknowledge bit. The acknowledge-related clock pulse is generated by the I2C master. 22 Functional Description Submit Documentation Feedback TVP5150AM1-EP Ultralow-Power NTSC/PAL/SECAM Video Decoder www.ti.com SLES213 – MAY 2008 3.15.1 I2C Write Operation Data transfers occur utilizing the following illustrated formats. An I2C master initiates a write operation to the TVP5150AM1 decoder by generating a start condition (S) followed by the TVP5150AM1 I2C address (see the following illustration), in MSB-first bit order, followed by a 0 to indicate a write cycle. After receiving an acknowledge from the TVP5150AM1 decoder, the master presents the subaddress of the register, or the first of a block of registers it wants to write, followed by one or more bytes of data, MSB first. The TVP5150AM1 decoder acknowledges each byte after completion of each transfer. The I2C master terminates the write operation by generating a stop condition (P).

The first phase is the address phase. In this phase, an I2C master initiates a write operation to the TVP5150AM1 decoder by generating a start condition (S) followed by the TVP5150AM1 I2C address, in MSB-first bit order, followed by a 0 to indicate a write cycle. After receiving acknowledges from the TVP5150AM1 decoder, the master presents the subaddress of the register or the first of a block of registers it wants to read. After the cycle is acknowledged, the master terminates the cycle immediately by generating a stop condition (P). Table 3-7.

After an acknowledge from the TVP5150AM1 decoder, the I2C master receives one or more bytes of data from the TVP5150AM1 decoder. The I2C master acknowledges the transfer at the end of each byte. After the last data byte desired has been transferred from the TVP5150AM1 decoder to the master, the master generates a not acknowledge followed by a stop. 3.15.2.1 Read Phase 1 Step 1 0 I2C Start (master) S Step 2 7 6 5 4 3 2 1 0 I2C General address (master) 1 0 1 1 1 0 X 0 Step 3 9 2 I C Acknowledge (slave) Step 4 I2C Write register address (master) A 7 6 5 4 3 2 1 0 Addr Addr Addr Addr Addr Addr Addr Addr Step 5 9 I2C Acknowledge (slave) A Step 6 0 2 I C Stop (master) P 3.15.2.2 Read Phase 2 Step 7 0 2 I C Start (master) S Step 8 7 6 5 4 3 2 1 0 I2C General address (master) 1 0 1 1 1 0 X 1 Step 9 9 I2C Acknowledge (slave) A Step 10 7 6 5 4 3 2 1 0 Data Data Data Data Data Data Data Data 2 I C Read data (slave) Step 11 (1) I2C Not Acknowledge (master) (1) 24 9 A Step 12 0 I2C Stop (master) P Repeat steps 10 and 11 for all bytes read.

In accordance with I2C specifications, the TVP5150AM1 decoder holds the I2C clock line (SCL) low to indicate the wait period to the I2C master. If the I2C master is not designed to check for the I2C clock line held-low condition, then the maximum delays always must be inserted where required. These delays are of variable length; maximum delays are indicated in the following diagram: Normal register writing addresses 00h to 8Fh (addresses 90h to FFh do not require delays). Start Slave address (B8h) Ack Subaddress Ack Data (XXh) Ack Wait 64 µs Stop The 64-µs delay is for all registers that do not require a reinitialization. Delays may be more for some registers. 3.16 Clock Circuits An internal line-locked PLL generates the system and pixel clocks. A 14.31818-MHz clock is required to drive the PLL. This may be input to the TVP5150AM1 decoder on terminal 5 (XTAL1), or a crystal of 14.31818-MHz fundamental resonant frequency may be connected across terminals 5 and 6 (XTAL2). Figure 3-5 shows the reference clock configurations. For the example crystal circuit shown (a parallel-resonant crystal with 14.31818-MHz fundamental frequency), the external capacitors must have the following relationship: CL1 = CL2 = 2CL – CSTRAY where CSTRAY is the terminal capacitance with respect to ground.

The frequency control word of the internal color subcarrier digital control oscillator (DTO) and the subcarrier phase reset bit are transmitted via terminal 23 (GLCO). The frequency control word is a 23-bit binary number. The frequency of the DTO can be calculated from the following equation: Fdto = (Fctrl/223) × Fsclk where Fdto is the frequency of the DTO, Fctrl is the 23-bit DTO frequency control, and Fsclk is the frequency of the SCLK.

The active-low reset bit occurs seven SCLKs after the transmission of the last bit of DCO frequency control. Upon the transmission of the reset bit, the phase of the TVP5150AM1 internal subcarrier DCO is reset to zero.

Hamming protection bits are ignored by the filter. For a WST system (PAL or NTSC), the packet prefix consists of two bytes so that two patterns are used. Patterns 3, 4, and 5 are ignored. The mask bits enable filtering using the corresponding bit in the pattern register. For example, a 1 in the LSB of mask 1 means that the filter module must compare the LSB of nibble 1 in the pattern register to the first data bit on the transaction. If these match, a true result is returned. A 0 in a bit of mask 1 means that the filter module must ignore that data bit of the transaction. If all zeros are programmed in the mask bits, the filter matches all patterns returning a true result (default 00h). Pattern and mask for each byte and filter are referred as <1,2><P,M><1,2,3,4,5>, where: <1,2> identifies the filter 1 or 2 <P,M> identifies the pattern or mask <1,2,3,4,5> identifies the byte number 58 Functional Description Submit Documentation Feedback TVP5150AM1-EP Ultralow-Power NTSC/PAL/SECAM Video Decoder www.ti.com SLES213 – MAY 2008 3.20.54 Teletext Filter Control Register Address BBh Default 00h 7 6 Reserved 5 4 3 Filter logic 2 1 0 Mode TTX filter 2 enable TTX filter 1 enable Filter logic allows different logic to be applied when combining the decision of filter 1 and filter 2 as follows: 00 = NOR (Default) 01 = NAND 10 = OR 11 = AND Mode 0 = Teletext WST PAL mode B (2 header bytes) (default) 1 = Teletext NABTS NTSC mode C (5 header bytes) TTX filter 2 enable 0 = Disabled (default) 1 = Enabled TTX filter 1 enable 0 = Disabled (default) 1 = Enabled If the filter matches or if the filter mask is all zeros, a true result is returned.

Reading data from the corresponding register does not clear the status flags automatically. These flags are only reset by writing a 1 to the respective bit. However, bit 6 is updated automatically. FIFO full error 0 = No FIFO full error 1 = FIFO was full during a write to FIFO. The FIFO full error flag is set when the current line of VBI data can not enter the FIFO. For example, if the FIFO has only ten bytes left and teletext is the current VBI line, the FIFO full error flag is set, but no data is written because the entire teletext line does not fit. However, if the next VBI line is closed caption requiring only two bytes of data plus the header, this goes into the FIFO, even if the full error flag is set. FIFO empty 0 = FIFO is not empty. 1 = FIFO is empty. TTX available 0 = Teletext data is not available. 1 = Teletext data is available. CC field 1 available 0 = Closed caption data from field 1 is not available. 1 = Closed caption data from field 1 is available. CC field 2 available 0 = Closed caption data from field 2 is not available. 1 = Closed caption data from field 2 is available. WSS available 0 = WSS data is not available. 1 = WSS data is available. VPS available 0 = VPS data is not available. 1 = VPS data is available.
