Preliminary Data Sheet
System Description
4096 frame colors are programmable by FRY, FRU, and FRV, 4 bits for each
component. Horizontal and vertical width of the frame are programmable independently
by FRWIDH and FRWIDV. If desired, frame color is displayed over the whole PIP size
or whole picture size of the main channel when PIPBG is set accordingly. 64 background
colors are programmable by BGY, BGU, BGV, 2 bits for each component. Alternatively
BGFRC sets the background to frame color.

16:9 Inset Picture Support
To remove dark stripes at 16:9 inset pictures the vertical display area is shrinkable with
VPSRED. The number of omitted lines depends on the vertical decimation factor.

Parent Clock Generation
The phase of the output signals is locked to the rising edge of the horizontal sync pulse.
The frequency varies in a certain range to ensure correct aspect ratio for 16:9
applications depending on HZOOM. The horizontal and vertical scaling can be used for
all display frequencies.
