The device integrates both audio and video drivers so that it can directly drive the SCART interface. All programmable functions of the device are controlled through a standard I2C serial interface and a set of internal registers. The device is designed to accept video signals from an auxiliary SCART connector, TV SCART connector, and an external video encoder/DAC device. The devices include a set of analog multiplexers that receive video signals from these sources and allow routing of the signals to the various video outputs. The video output drivers have a nominal gain of 2 V/V to allow for a series resistance of 75Ω prior to the 75Ω termination. A block diagram of the video switching function is provided in Figure 1. Details of the register settings are provided in the section titled “Serial Port Register Tables”. The device will interface to an external video encoder that provides six video outputs. In addition, the 5002R includes two programmable digital outputs and provides inputs for the TV SCART audio/video.

Page: 2 of 30 © 2008 TERIDIAN Semiconductor Corporation Rev 2.1 AVPro® 5002R Dual SCART A/V Switch DATA SHEET TV RGB Outputs The device accepts RGB video signals from two sources. The Aux_R, Aux_G, Aux_B input pins are typically connected to the auxiliary SCART connector. The Enc_R, Enc_G, Enc_B input pins are connected to the RGB outputs of an external video encoder device. These outputs are used as a video source for the TV SCART pins TV_R, TV_G, and TV_B. The RGB video source is selected by setting the lower three (3) bits of serial port Register 1. When these bits are set to xxxxx000, the RGB source will be the encoder. When these bits are set to xxxxx001, the source will be the auxiliary port. The TV RGB outputs can be muted independently from the TV composite outputs. Setting Bit 6 of Register 1 low (0) will allow normal operation. Setting Bit 6 high (1) will set the TV RGB outputs to the blank level. RGB Gain: The gain of the RGB outputs can be adjusted to one of four different levels. Bits 4 and 5 in Register 2 set the gain of the RGB output amplifiers according to the following table: Bit 5 Bit 4 0 0 1 1 0 1 0 1 RGB Amplifier Gain Gain = 2 V/V = A0 Gain = A0 - 10% Gain = A0 - 20% Gain = A0 - 30% DC Restore: The device will generate a DC restore level on each video output based on timing referenced to a horizontal sync pulse. When the sync pulse is detected, the DC restore circuit will act to position the blank level to 1.2V at the respective RGB output pins and the respective composite output pins (0.6V at the respective RGB and composite video output load). The device can be programmed to look for the horizontal sync pulse on all of the RGB input pins or on the associated composite video input pin (Aux_YC for the auxiliary port or Enc_YC for the external encoder). Bit 7 of Register 1 determines the horizontal sync source. At power-up, this bit defaults to a low (0) state, which programs the device to look for sync detect on the RGB input signals. In this mode, the device can detect a horizontal sync on any of the three RGB input signals. When Bit 7 is set to a high (1) state, the device will look for a sync detect from the signal on either the Aux_YC or Enc_YC pin depending on which source is selected. Blanking: The signal on the Blank output pin is determined by the state of two MSBs in Register 2 according to the following table: Page: 3 of 30 Bit 7 Bit 6 0 0 1 1 0 1 0 1 Blank source BLANK = ABLANK BLANK = EBLANK BLANK = 0V BLANK = 4V @ IC output pin The user must insure that the source of the Blank output is the same as the source for the RGB outputs, i.e. ABLANK is selected when the auxiliary RGB is active and EBLANK is selected when the encoder RGB is active. TV Composite Output The device provides inputs for two composite video sources that can be switched to the TV SCART composite video pin, TV_YCout. The Aux_YC input pin is typically connected to the “Video In” pin (pin 20) on the auxiliary SCART connector. The Enc_YC input pin is typically connected to the “YC” or “CVBS” output from the external video encoder device. Selection of the video source for the TV composite output is accomplished when the RGB video source is selected (see the register tables). When Register 1 is set to xxxxx000, the Encoder input is selected and when set to xxxxx001, the Auxiliary input is selected. TV SVHS Output Mode The device supports SVHS video format. The SVHS mode is selected for the TV SCART using the lower three (3) bits of Register 1(except for SVHS Enc 4 mode). When the SVHS mode is selected, the TV_YCout pin will provide the luminance signal output from the selected source. The chroma output will be provided on the TV_R pin. The video source for SVHS mode can be either the auxiliary port or the encoder port. When the auxiliary port is selected as the video source, the video on Aux_R will be provided at the TV_R output pin and the Aux_YC video will be provided at the TV_YCout pin. The device will support SVHS mode for four encoder interface formats. The first encoder interface format accepts chroma signals on the Enc_C pin and luminance signals on the Enc_Y pin. This is designated "SVHS, Enc 1" mode. The second format will receive chroma information on the Enc_B pin and luminance information on Enc_G. This format is designated "SVHS, Enc 2". The third format will receive chroma information from the Enc_R pin and luminance information from the Enc_G pin. This mode is designated “SVHS, Enc 3” on the serial port register table. For these three modes, audio will come from the Lin/Rin inputs. The fourth format is designated "SVHS Enc 4" (not available in the 48QFN package option). It is selected by setting register one to xx110xxx. Chroma information is received on the Enc2_C input pin. © 2008 TERIDIAN Semiconductor Corporation Rev 2.1 AVPro® 5002R Dual SCART A/V Switch DATA SHEET luminance is received on the Enc2_Y input pin. For this mode only, audio will come from the TV_Lin/TV_Rin inputs, and the video will have chroma output on Aux_Cout, and luminance output on Aux_YCout. When the SVHS mode is selected, the DC restore on the TV_R pin will average to approximately 1.7 VDC at the output pin. The DC restore circuit will act to position the blank level to 1.2V at the TV_YCout video output pin. The TV_G and TV_B outputs will be set to 0 VDC when the SVHS mode is active. RF Modulator Output The device provides an output, Mod_YC, to drive an external RF modulator. The Mod_YC output is a unity gain amplifier designed to drive a 1kΩ load or higher. When the device is operating in the RGB mode, the signal on the Mod_YC output will follow the same source as the TV_YCout output. Auxiliary SVHS Output Mode In the SVHS mode, Pin 15 on the auxiliary SCART connector provides chroma information. To support this, the auxiliary port on the 5002R includes a chroma input pin (Aux_Cin) that is externally AC coupled to Pin 15 on the auxiliary SCART connector. The device also includes an output pin (Aux_Cout) that provides a chroma output to Pin 15 (RED) on the auxiliary SCART connector. When connected with the Aux_R and Aux_Cin pins, this forms a bi-directional port as shown in the diagram below: AuxiliaryS CART Pin 15 When the device is in the SVHS mode, the Mod_YC output can be driven by several sources depending on the SVHS video source. These various options are detailed in the serial port register table. One case that requires additional detail is the auxiliary SVHS mode. In the SVHS mode, the Aux_YC video input will only provide luminance information. Composite video for the modulator output must be generated by summing this luma information with the chroma information from the auxiliary port. The input pin labeled Aux_Cin is used for this purpose. The Aux_Cin input pin is AC coupled to the same source that provides the input signal to Aux_R. An internal summing node combines the video signal on Aux_Cin (chroma) with the video signal on Aux_YC (luma) to generate a composite video signal. In the auxiliary SVHS mode, this signal is provided at the Mod_YC pin. TV Composite Video Mute The TV composite video outputs can be muted by programming the lower three (3) bits in Register 1. The power-up default condition is xxxxx111, (Auxiliary RGB source) which sets the TV composite video outputs to 0 VDC and switches the TV audio outputs to Aux_Lin/Aux_Rin. Setting these bits to xxxxx110 (Encoder RGB source) will also mute the TV composite video outputs and switch the TV audio outputs to Lin/Rin. Auxiliary Composite Output The auxiliary port includes a composite video output pin (AUX_YCout) that is typically connected to the “Video Out” pin (pin 19) on an auxiliary SCART connector. Bits 3-5 in Register 1 determine the source for the AUX_YCout pin as well as for the Aux_Cout. See register table. Page: 4 of 30 Aux_Cout Mux 75 Mux Aux_R Aux_Cin Mux BI-DIRECTIONAL PIN CIRCUIT Using this configuration, the device will support SVHS mode for four encoder interface formats. The first encoder interface format will receive chroma information from the Enc_C pin and luminance information from the Enc_Y pin. This format is designated “SVHS, Enc 1”. The second format will receive chroma information on the Enc_B input and luminance information on Enc_G. This format is designated "SVHS, Enc 2". The third format will receive chroma information from the Enc_R pin and luminance information from the Enc_G pin. This mode is designated “SVHS, Enc 3” on the serial port register table. For these three modes, audio will come from the Lin/Rin inputs. The fourth format is designated "SVHS Enc 4" (not available in the 48 QFN option). Chroma information is received on the Enc2_C input pin and the luminance is received on the Enc2_Y input pin. For this mode only, audio will come from the TV_Lin/TV_Rin inputs. When the SVHS mode is selected, the DC restore on the Aux_Cout pin will average to approximately 1.7 VDC at the pin (0.85 at the video output load). The DC restore on the Aux_YCout pin will set the blank level to 1.2 V at the IC pin or approximately 0.6 V across the video output load. © 2008 TERIDIAN Semiconductor Corporation Rev 2.1 AVPro® 5002R Dual SCART A/V Switch DATA SHEET The RGB mode of operation requires special consideration. The output driver on the Aux_Cout pin acts as part of the load for the RED signal on pin 15 of the SCART connector. Register 1 must be set to x0011001 to select the auxiliary SCART as the RGB source for the TV outputs and selects the external video encoder as the source for the Auxiliary SCART connector. This provides an output impedance of about 0Ω on the Aux_Cout pin. This setting also allows the Enc_C pin to pass through the Aux_Cout pin. Due to this, the outputs of the external video encoder must be disabled to prevent corruption of the incoming RED video signal. TV_Fnc pin as an output, or vice versa. This mode is useful when the rest of the system powers down and all signals from the auxiliary port are passed directly through to the TV port, or vice versa. When a function pin is set as an input, the voltage on that pin is applied to an internal comparator. The comparator senses the voltage on the input pin and sets the two (2) LSBs in the read register according to the following table: Auxiliary Video Mute All auxiliary video outputs can be simultaneously disabled by programming Bits 3-5 in Register 1. The power-up default condition is xx111xxx, which sets all auxiliary video outputs to 0 VDC and switches the auxiliary audio outputs to Lin/Rin. When a function pin is set as an output, the output level for the pin is determined by the state of the two LSBs in Register 2, according to the following table: Function Switching The device provides functions switching pins for both the Auxiliary (Aux_Fnc) and TV (TV_Fnc) SCART ports. Both of these pins are bi-directional. The direction of the pins is determined by setting bits in Register 2 according to the following table: Bits xxxx00xx xxxx01xx xxxx10xx xxxx11xx Aux_Fnc output output input Passthru I/O TV_Fnc output input output Passthru O/I For the case where Register 2 is set to xxxx11xx, the input signal on the Aux_Fnc pin is passed directly through to the Input voltage < 2.0 V 4.5 to 7.0V >9.5 V Bits xxxxxx00 xxxxxx01 xxxxxx10 xxxxxx11 Bits xxxxxx00 xxxxxx01 xxxxxx10 Output voltage ~0 V ~6 V ~ 11 V ~ 11 V Function Normal TV 16:9 aspect Peritelevision Function Normal TV 16:9 aspect Peritelevision Peritelevision Note that both the Aux_Fnc pin and the TV_Fnc pin can be set as outputs simultaneously, however they will have the same output voltage. The function output circuit includes short circuit protection. When a function pin is in the 6V or 11V output mode, if the SCART connection is shorted to ground, then the output is disabled. Likewise, when a function pin is in the 0V output mode, if the SCART connection is connected to a voltage source, then the output is disabled. The load for the function outputs is designed to be 10kΩ or higher.

As a result, the video selection determines which audio signals will be switched to a given SCART output. Refer to the serial port register table for more information. Also see the audio switching block diagram shown in Figure 2. The 5002R provides inputs for the auxiliary audio source (Aux_Lin/Aux_Rin), a stereo DAC associated with the video encoder inputs (Lin/Rin), and inputs from the TV SCART (TV_Lin/TV_Rin). TV Audio Operation The audio source for the TV port is selected in concert with the video source using the three (3) LSBs of Register 1. The selected audio signals are input to internal multiplexers that allow the user to select between mono and stereo output options. Bits 4 and 5 of Register 3 control the stereo/mono selection according to the following table: Bit 1 0 0 1 1 Bit 0 0 1 0 1 TV left source left input left + right left input right input TV right source right input left + right left input right input At power-up, these bits default to 00 putting the device in the stereo mode. Volume Control: The left and right TV audio channels can be selected to pass through volume control circuits. Each volume control circuit is formed by a serially connected amplifier and attenuator pair. The amplifier is programmed by register 4, bit 2( “0” for 0 dB and “1” for 6 dB gains ). The attenuator is programmed by the lower 6 bits of register 0( “xx000000” for 0 dB and “xx111111” for –63 dB attenuation, in –1 dB steps ). DAC Input Gain (Lin/Rin): To support audio DACs that have a limited output range, the 5002R provides programmable gain amplifiers on the Lin and Rin inputs. The gain is set by Bits 2 and 3 of Register 3, according to the following table: Bit 3 0 0 1 1 Bit 2 0 1 0 1 Page: 6 of 30 TV SCART Audio Outputs: The first pair of signals is labeled TV_Lout and TV_Rout on the block diagram. TV_Lout and TV_Rout are typically used to drive the TV SCART audio pins. These outputs also have an internal multiplexer that allows the user to select TV audio either before or after the internal volume control function. When Bit 0 in Register 4 is set low (0), the volume control is used. When this bit is set high (1), the volume control is bypassed. The power-up default state is volume control active. TV Audio Line Outputs: The second pair of signals is labeled Lout and Rout on the block diagram. Lout and Rout are standard line outputs. The Lout/Rout outputs have an internal multiplexer that allows the user to select TV audio either before or after the internal volume control function. When Bit 1 in Register 4 is set low (0), the volume control is used. When this bit is set high (1), the volume control is bypassed. The power-up default state is volume control active. In addition, the audio inputs from the TV SCART connector (TV_Lin/TV_Rin) can be switched to the line outputs. This is controlled by bit-3 of Register 4. Setting this bit low (0) is the normal operation where the line outputs follow the TV SCART outputs. Setting this bit high (1) will switch the line outputs to the audio source on the TV_Lin/TV_Rin inputs. RF Mono Output: The TV_Lout and TV_Rout signals are also summed internally to generate a mono audio signal for an external RF modulator. This output is labeled Mod_Mono. The internal summing circuit is after the volume control mux so the audio control on this output will be the same as that selected for the TV_Lout and TV_Rout outputs. TV Audio Mute: A mute function is provided for all TV audio outputs. The mute function is controlled by setting Bit 6 in Register 0. When this bit is set to a high state (1), all TV audio outputs are muted. This will be the default condition at power-up. When the bit is set to a low state (0), the audio path will be in normal operating mode. This bit can be set independent of the volume control such that the outputs can be muted before any change in volume, or any switching of audio sources. Gain Gain = 0 dB Gain = 6 dB Gain = 9 dB Gain = 11.5 dB © 2008 TERIDIAN Semiconductor Corporation Rev 2.1 AVPro® 5002R Dual SCART A/V Switch DATA SHEET Auxiliary Audio Operation The auxiliary port includes stereo audio outputs for a SCART connector (Aux_Lout, Aux_Rout) and a mono audio output (Aux_Mono). These outputs can choose between the Lin/Rin input pins or the TV_Lin/TV_Rin input pins. The audio inputs are switched in concert with the associated video inputs according to Bits 3-5 in Register 1. Internal multiplexers allow the Aux_Lout and Aux_Rout outputs to be configured into either stereo or mono audio outputs. The two MSBs of Register 3 control the stereo/mono selection according to the following table: Bit 1 Bit 0 0 0 1 1 0 1 0 1 Aux_Lout source Lin Lin+Rin Lin Rin Aux_Rout source Rin Lin+Rin Lin Rin At power-up, these bits default to 00 putting the device in the stereo mode. The Aux_Mono output is generated through an internal summing node that combines the signals of the Aux_Lout and Aux_Rout outputs. All three auxiliary audio outputs can be muted by setting the MSB in Register 0. This bit is set high (1) at power-up causing the outputs to be muted. Setting this bit low (0) enables all auxiliary audio outputs. Digital Outputs The 5002R provides two programmable digital outputs, DO_0 and DO_1 (not available on the 48 QFN option). These pins are general purpose outputs programmed by setting Bit 0 and 1 in Register 3. Setting the register bits to 0 puts these outputs in the logic low state. Setting the register bits to 1 puts the outputs in the logic high state. Internal pull-up resistors (approximately 17kΩ) are included on these pins. Serial Port Definition Internal functions of the device are monitored and controlled by a standard inter-IC (I2C)bus with data being transferred MSB first on the rising edge of the clock. The serial port operates in a slave mode only and can be written to or read from. The device uses 7bit addressing, and does not support 10-bit addressing mode. The write register data is sent sequentially, Page: 7 of 30 such that if register 4 is to be programmed, then registers 0, 1, 2, 3 and 4 need to be sent. If only register 2 needs to be programmed, then only registers 0, 1 and 2 data need to be sent. It will support standard and fast bus speed. The default address of the device is 1001000x (1001000 for Write and 10010001 for Read). The 5002R includes a read register in which the upper four bits identify the specific chip within the AVPro® family. This allows a single application platform and software to work with a wide variety of AVPro® chips. The ID code for the 5002R is 0001. Data Transfers A data transfer starts when the SDATA pin is driven from HIGH to LOW by the bus master while the SCLK pin is HIGH. On the following eight clock cycles, the device receives the data on the SDATA pin and decodes that data to determine if a valid address has been received. The first seven bits of information are the address with the eighth bit indicating whether the cycle is a read (bit is HIGH) or a write (bit is LOW). If the address is valid for this device, on the falling SCLK edge of the eighth bit of data, the device will drive the SDATA pin low and hold it LOW until the next rising edge of the SCLK pin to acknowledge the address transfer. The device will continue to transmit or receive data until the bus master has issued a stop by driving the SDATA pin from LOW to HIGH while the SCLK pin is held HIGH Write Operation: When the read/write bit (LSB) is LOW and a valid address is decoded, the device will receive data from the SDATA pin. The device will continue to latch data into the registers until a stop condition is detected. The device generates an acknowledge after each byte of data written. Read Operation: When the read/write bit (LSB) is HIGH and a valid address is decoded, the device will transmit the data from the internal register on the following eight SCLK cycles. Following the transfer of the register data and the acknowledge from the master, the device will release the data bus. Reset: At power-up the serial port defaults to the states indicated in boldface type. The device also responds to the system level reset that is transmitted through the serial port. When the master sends the address 00000000 followed by the data 00000110, the device resets to the default condition. © 2008 TERIDIAN Semiconductor Corporation Rev 2.1 AVPro® 5002R Dual SCART A/V Switch DATA SHEET SERIAL PORT REGISTER TABLES Read register Device Address = 10010001 FUNCTION Function Control Input Not Used Device ID code BITS xxxxxx00 xxxxxx01 xxxxxx10 xxxx00xx xxxx11xx 0001xxxx DESCRIPTION TV_Fnc or Aux_Fnc pin level =Level 0 < 2V TV_Fnc or Aux_Fnc pin level =Level 1A ~6.0V TV_Fnc or Aux_Fnc pin level = Level 1B >9.5V Ignore these bits This code identifies the device type as the 5002R Write Registers: Device Address = 10010000 (Bold indicates default setting) Register 0: Audio Control Register A FUNCTION Volume Control Attenuation for TV, Line or Mod_Mono audio TV audio mute AUX audio mute Page: 8 of 30 BITS xx000000 xx011111 xx100000 xx111111 x0xxxxxx x1xxxxxx 0xxxxxxx 1xxxxxxx DESCRIPTION Audio volume = maximum (0 dB) Audio volume = minimum (-31 dB attenuation) Extended TV audio volume control range.

In some applications (such as BskyB), independent control of these output voltages is required. An external circuit pictured below that will allow independent control. The internal register bits should be used to control the Aux_Fnc pin as this pin is typically bi-directional. The control for the TV_Fnc pin is then controlled by the external circuit. The DO_0 and DO_1 pins are used to switch two external transistors to create the three different voltage levels. The 150Ω resistor is used to limit the current through Q2. With a SCART load of 10kΩ, the voltage at the TV_Fnc pin is as follows: DO_0 = 0, DO_1 = 0; TV_Fnc = 10.9V DO_0 = 1, DO_1 = 0; TV_Fnc = 5.7V DO_0 = 0, DO_1 = 1; TV_Fnc = 0.0V 12V 1kΩ 150Ω TV_Fnc 1kΩ DO_0 DO_1 Q1 Q2 Note: DO_0 and DO_1 are not available on the 48 QFN package.

In order to get the correct 75Ω load impedance, the Aux_Cout amplifier needs either a DC bias, an extra resistance to ground, or a FET pulldown. 1). To select an internal DC bias for the Aux_Cout amplifier, the Aux A/V source should be set for S-video mode (SVHS Enc 1, Enc 2, Enc 3 or Enc 4) per the following table. This puts 0.9 VDC bias at the input, or about 1.8V at the Aux_Cout pin, and 0.9V at the auxiliary SCART connector when terminated (driven) in a 75Ω system. Therefore, the outputs of the external video encoder must be disabled in this mode in order to prevent corruption of the incoming RED/Chroma video signal. 2). As an alternative, to select a 0V DC bias for the Aux_Cout amplifier, the Aux A/V source should select one of the Composite modes (Enc1, ENC2 or TV) or Aux mute in the following table. In this mode, the internal amplifier bias set to 0V, but amplifier is a weak pulldown. The amplifier is biased between ground and +5V, as such, the output impedance of the Aux_Cout is around 100Ω including the 75Ω series resistor. A shunt resistor of 330 to 470 Ω will compensate, but will slightly lower the Aux_Cout chroma signal. 3). Another option is to add a FET with ~20Ω series resistor from the Aux_Cout to ground. Select 0VDC bias for the Aux_Cout amplifier, and bias the FET in the “ON” or conducting state. The Aux A/V source should select one of the Composite modes (Enc1, ENC2 or TV) or Aux mute. See the Register 1: Audio/Video Control bit table for settings. This method will compensate for the Aux_Cout pin pulldown, and not significantly reduce the Aux_Cout chroma signal. 5002R Mux Aux_Cout 75 Ω Aux_R Mux Aux_Cin Mux Auxiliary SCART Pin 15 Option 2 R = (330-470Ω) or Option 3 FET + R = 20 Ω Note: Aux_Cin is not available on the 48QFN package HOT-PLUG OF SCART CONNECTORS Semiconductor ICs can be sensitive to discharges caused by floating chassis grounds between audio/video equipment. This is observed when the SCART cables are repeatedly connected and disconnected while the ICs are powered on inside the IRD. When the SCART cable is unplugged, an AC potential can exist between equipment. When the SCART cable is plugged back into the IRD, the AC potential discharges through the SCART connector. If the discharge occurs through the shield of the SCART connector or the ground pins, there is no problem. If the discharge occurs through the signal pins, semiconductor devices can experience potential issues. These issues will occur if the pulse created by the discharge has a fast rising edge, typically a few hundred pico-seconds. This is an order of magnitude faster than a standard ESD pulse so the internal ESD diodes of ICs will not respond fast enough to protect the device. This issue can be resolved by placing a small shunt capacitor on each SCART I/O pin. The capacitor slows the rising edge of the discharge pulse and allows the internal ESD diodes to react to the discharge. An exact value should be calculated for each signal line depending upon the signal type so as to avoid roll-off of the intended signal.
