Pin Type Description
QFN LQFP
Aux Chroma Output: This output provides a chroma signal to the auxiliary
Aux_Cout
47
62
O
SCART connector to support SVHS operation. This pin is typically AC coupled
to pin 15 of the auxiliary SCART connector. When the S-video mode is
selected, a chroma signal from the video encoder is output to this pin.
TV Modulator Video Output: This pin provides composite video for an external
Mod_YC
39
53
O RF modulator. The signal on this pin follows the composite video output to the
TV_YCout pin.
TV Video Output: This pin is the composite video output to the TV SCART
TV_YCout 40
54
O connector (pin 19). In the SVHS mode, this pin provides luminance
information.
TV_R
42
56
O
TV Red Output: This pin provides Red video to the TV SCART connector (pin
15). In SVHS mode, this pin provides the chroma information.
TV_G
44
58
O
TV Green Output: This pin provides Green video to the TV SCART connector
(pin 11).
TV_B
45
59
O
TV Blue Output: This pin provides Blue video to the TV SCART connector (pin
7).
TV_Lout
16
23
O
TV Left Audio Output: This pin is the output to the left channel audio (pin 3) of
the TV SCART connector.
TV_Rout
21
28
O
TV Right Audio Output: This pin is the output to the right channel audio (pin1)
of the TV SCART connector.
TV_Fnc
TV Function Pin: This is a bi-directional pin. As an input, it digitizes the analog
27
36
I/O voltage on the TV SCART function pin (8). As an output, it puts out one of
three voltage levels to the TV SCART function pin.
