FUNCTIONAL DESCRIPTION
SCART VIDEO SWITCHING
The 5002CL 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. Since the –5V supply biases the substrate of the
device, the supplies sequencing should be such that
the –5V supply turns on first and turns off last. 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 1.83 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”.
The device will interface to an external video encoder
that provides six video outputs. In addition, the 5002CL
includes two programmable digital outputs and
provides inputs for the TV SCART audio/video.

TV RGB OUTPUTS
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.
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.
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).
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.
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
RGB Amplifier Gain

Gain = 1.83 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 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 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 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". It is selected by setting register one to xx110xxx.
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, and the video will have chroma
output on Aux_Cout,
and luminance output on
Aux_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:
Bit 7

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 video output

load. The TV_G and TV_B outputs will be set to 0 VDC
when the SVHS mode is active.
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 following diagram:
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.
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
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 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.

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". 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.
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.
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 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
as well as for the Aux_Cout 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.
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 5002CL includes a
chroma input pin (Aux_Cin) that is externally AC
coupled to Pin 15 on the auxiliary SCART connector.

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:

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.
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.
When a function pin is set as an input, the voltage on that pin
is applied to an internal comparator. The comparator senses

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 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 5002CL 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 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.
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

Bit 0

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

AUXILIARY AUDIO OPERATION
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 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 5002CL 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 5002CL 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 following table:

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
source
Rin
Lin+Rin

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.
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 5002CL 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 pullup resistors (approximately 30kΩ) 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
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,
such that if register 4 is to be programmed, then
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.
