H Delay parameter allows
moving the entire constellation
of output pulses relative to the
incoming H
Sync Tip clamp may be
selected for delay or triggered
from incoming sync
depending on application.

Numerical value taken as unsigned
binary. Actual no. of pixels is:
Do not vary pixel [10:0] by more than
±6% from nominal.
If PHERR enable and VGA = 1, the
actual no. of pixels is:
P[10:0]=2x(no. of pixels per line)–512
Low = Back Porch Clamp
High = Burst Gate
Low = regenerated C
High = raw C
High = raw Clamp
Low = sync separator active
High = TTL horiz + vert sync input
Low = narrow blanking
High = wide blanking
