Reset
The RESET pin is used to return the decoder to an initializa-
tion state. This pin should be used after a power-up to set
the part into a known state. The internal registers are
returned to their RESET state and the Serial I
2
C port is
returned to inactive state. The RESET pin is an active low
signal and should be asserted for minimum of 1 CLK cycle.
After a RESET or a software reset has occurred all output
pins are three-stated. The following pins must be pulled high
to ensure proper operation:
HSYNC
VSYNC
DVLD
ACTIVE
FIELD
A 10K or smaller pullup resistor to V
CC
is recommended.

NOTES:
1. Y0 is the first active luminance pixel of a line. Cb0 and Cr0 are first active chrominance pixels in a line. Cb and Cr will alternate every cycle
due to the 4:2:2 subsampling.
2. Active is asserted for lines 22-262.5 and 285.5-525. DVLD is asserted for every valid pixel during both active and blanking regions. DVLD
is asserted during vertical and horizontal sync.
