FUNCTIONAL DESCRIPTION
SCART VIDEO SWITCHING
The 5002C is an audio/video switching device. The
device integrates both audio and video drivers so
that it can directly drive the SCART interface. The
use of a -5 volt supply eliminates the need for AC
coupling capacitors on the audio outputs and the
SCART audio inputs. All programmable functions of
2
the device are controlled through a standard I C
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 2.0 V/V to allow for a series
resistance of 62 ohms prior to the 75 ohm
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”.

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 xxxxxx00, the RGB
source will be the encoder. When these bits are set
to xxxxxx01, 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.

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 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).
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:

RGB Amplifier Gain
Gain = 2.0 V/V = A0
Gain = A 0 - 10%
Gain = A 0 - 20%
Gain = A 0 - 30%
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. 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.
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 0.6 V at the respective
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 a 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.
The device will support SVHS mode for three
encoder interface formats. The first encoder
interface format accepts chroma signals on the
Enc_C pin and luma 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 luma information on Enc_G. This format is
designated "SVHS, Enc 2". The third format will
receive chroma information from the Enc_R pin and
luma information from the Enc_G pin. This mode is
designated “SVHS, Enc 3”.
When the SVHS mode is selected, the DC restore
on the TV_R pin will average to approximately 1.8
VDC at the output pin. The DC restore circuit will act
to position the blank level to 0.6 V at the TV_YCout
Blanking: The signal on the Blank output pin is
determined by the state of two MSBs in Register 2
according to the following table:

AUXILIARY SVHS OUTPUT MODE
video output load. The TV_G and TV_B outputs will
be set to 0 VDC when the SVHS mode is active.
In the SVHS mode, Pin 15 on the auxiliary SCART
connector provides chroma information. To support
this, the auxiliary port on the 5002C includes a
chroma input pin (Aux_Cin) that is externally AC
coupled to Pin 15 on the auxiliary SCART connector.
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 1k 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 RGB and TV_YCout
outputs.
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 bidirectional port as shown in the following diagram:
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.
Aux_Cout
Mux
One case that requires additional detail is the
auxiliary SVHS mode. In the SVHS mode, the
Aux_YC video input will only provide luma
information. Composite video for the modulator
output must be generated by summing this luma
information with 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.

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 luma 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 luma information
on Enc_G. This format is designated "SVHS, Enc 2".
The third format will receive chroma information from
the Enc_R pin and luma 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". Chroma
information is received on the Enc2_C input pin and
the luma is received on the Enc2_Y input pin. For this
mode only, audio will come from the TV_Lin/TV_Rin
inputs.
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, 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 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 on an auxiliary SCART connector.
Bits 3-5 in Register 1 determine the source for the
AUX_YCout pin. When these bits are set to
xx000xxx, the video source will be the Enc_B input.
When these bits are set to xx001xxx, the video
source will be the Enc_YC input. When these bits
are set to xx010xxx, the video source will be the
TV_YCin input.
When the SVHS mode is selected, the DC restore
on the Aux_Cout pin will average to approximately
0.9 VDC 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.

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.

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:
When a function pin is set as an output, the output level
for the pin is determined by the state of the two LSBs
Register 2, according to the following table:

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 10k or higher.
When a function pin is set as an input, the voltage on that
pin is applied to an internal comparitor. The comparitor
senses the voltage on the input pin and sets the two (2)

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.
For the case where Register 2 is set to xxxx11xx, the
input signal on the Aux_Fnc pin is passed directly
through to the 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.

SCART AUDIO SWITCHING
The audio inputs are considered to be associated
with the respective video inputs. 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.

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:

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.
The 5002C provides inputs for the auxiliary audio
source (Aux_Lin/Aux_Rin), a stereo DAC associated
with the video encoder inputs (L in/Rin), and inputs
from the TV SCART (TV_Lin/TV_Rin).

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 bit3 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.
TV right source
right input
left + right

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
attenuations, in –1 dB steps ). Only the lower 5 bits
are guaranteed for accuracy( 0 to –31 dB ).
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.
DAC Input Gain (Lin/Rin): To support audio DACs
that have a limited output range, the 5002C 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:
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.

AUXILIARY AUDIO OPERATION
register 0, 1, 2, 3 and 4 need to be sent. If only
register 2 needs to be programmed, then only
register 0, 1 and 2 data needs to be sent. It will
support standard and fast bus speed. The default
address of the device is 1001000x.
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.
The 5002C 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 5002C is 0001.
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

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
Aux_Rout

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 powerup causing the outputs to be muted. Setting this bit
low (0) enables all auxiliary audio outputs.
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.
DIGITAL OUTPUTS
The 5002C provides two programmable digital
outputs, DO_0 and DO_1. 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 30k) are included on
these pins.
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.
SERIAL PORT DEFINITION
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. The device
also generates an acknowledge.
Internal functions of the device are monitored and
2
controlled by a standard inter-IC (I C)bus. The serial
port operates in a slave mode only and can be
written to or read from. The device uses 7-bit
addressing, and does not support 10-bit addressing
mode. The write register data is sent sequentially,
such that if register 4 is to be programmed, then
