VI_4_A: Analog video input for CVBS/Y
Up to 10 composite, 4 S-video, and 2 composite or 3 component video inputs (or a combination thereof)
can be supported.
The inputs must be ac-coupled. The recommended coupling capacitor is 0.1
F.
The possible input configurations are listed in the input select register at I2C subaddress 00h (see Section
Clock Signals
DATACLK
40
O
Line-locked data output clock
XTAL1
74
I
External clock reference input. It can be connected to an external oscillator with a 1.8-V compatible clock
signal or a 14.31818-MHz crystal oscillator.
XTAL2
75
O
External clock reference output. Not connected if XTAL1 is driven by an external single-ended oscillator.

C_[9:0]/
GPIO[9:0]
57, 58,
59, 60,
63, 64,
65, 66,
69, 70
I/O
Digital video output of CbCr, C[9] is MSB and C[0] is LSB. Also, these terminals can be programmable
general-purpose I/O.
For the 8-bit mode, the two LSBs are ignored. Unused outputs can be left unconnected.
The C_1 terminal needs a pulldown resistor (see Figure 51).
Y[9:0]
43, 44,
45, 46,
47, 50,
51, 52,
53, 54
O
Digital video output of Y/YCbCr, Y[9] is MSB and Y[0] is LSB.
For the 8-bit mode, the two LSBs are ignored. Unused outputs can be left unconnected.
Miscellaneous Signals
GPIO
35
I/O
Programmable general-purpose I/O
GLCO/I2CA
37
I/O
Genlock control output (GLCO) uses real time control (RTC) format.
During reset, this terminal is an input used to program the I2C address LSB.
INTREQ

Not connected. These terminals can be connected to power or ground (compatible with TVP5146
terminals), internally floating.
PWDN
