Dual SCART A/V Switch

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:
Bits
Aux_Fnc
output
output
input
Passthru I/O
TV_Fnc
output
input
output
Passthru O/I
xxxx
00
xx
xxxx01xx
xxxx10xx
xxxx11xx
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.
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)
LSBs in the read register according to the following table:
Input voltage
Bits
< 4.0 V
xxxxxx00
4.0 to 8.0V
xxxxxx01
>8.0 V
xxxxxx10
Function
Normal TV

Peritelevision
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:
Bits
Output voltage
~0 V
~6 V
~ 11 V
~ 11 V

xxxxxx11
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 10k or higher.
