VI_1_x: Analog video input for CVBS/Pb/B/C
VI_2_x: Analog video input for CVBS/Y/G
VI_3_x: Analog video input for CVBS/Pr/R/C
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
µ
F.
The possible input configurations are listed in the input select register at I2C subaddress 00h (see
Section 2.11.1).
Clock Signals
DATACLK
40
O
Line-locked data output clock.
XTAL1
74
I
External clock reference input. It may 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.

63, 64,
65, 66,
69, 70
O
Digital video output of CbCr, C[9] is MSB and C[0] is LSB. Unused outputs can be left unconnected. Also,
these terminals can be programmable general-purpose I/O.
For the 8-bit mode, the two LSBs are ignored.
D_BLUE
58
I
Digital BLUE input from overlay device
D_GREEN
59
I
Digital GREEN input from overlay device
D_RED
60
I
Digital RED input from overlay device
FSO
57
I
Fast-switch overlay between digital RGB and any video
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
FSS/GPIO
35
I/O
Fast-switch (blanking) input. Switching signal between the synchronous component video (YPbPr/RGB)
and the composite video input.
Programmable general-purpose I/O
GLCO/I2CA
37
I/O
Genlock control output (GLCO). Two Genlock data formats are available: TI format and real time control
(RTC) format.
During reset, this terminal is an input used to program the I2C address LSB.
INTREQ
30
O
Interrupt request
PWDN
33
I
Power down input:
1 = Power down
0 = Normal mode
RESETB
34
I
Reset input, active low
