Circuit- and IC Description
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 μF.
The possible input configurations are listed in the input select register at I 2 C subaddress 00h (see
Section 2.11.1).
Line-locked data output clock.
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.
External clock reference output. Not connected if XTAL1 is driven by an external single-ended oscillator.
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.
Digital BLUE input from overlay device
Digital GREEN input from overlay device
Digital RED input from overlay device
Fast-switch overlay between digital RGB and any video
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.
Fast-switch (blanking) input. Switching signal between the synchronous component video (YPbPr/RGB)
and the composite video input.
Programmable general-purpose 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 I 2 C address LSB.
Interrupt request
Power down input:
1 = Power down
0 = Normal mode
Reset input, active low
