3.2 Input Synchronization
The GF9331 obtains relevant timing information from either embedded TRS
information or externally supplied H_IN, V_IN sand F_IN signals.
When FVH_EN is set HIGH using either the host interface or the external pin, the
GF9331 relies on the externally supplied H_IN, V_IN and F_IN signals for timing
information. When FVH_EN is set LOW, the GF9331 extracts the embedded TRS
timing information from the video data stream and ignores any timing information
present of the F_IN, V_IN and H_IN pins.
3.2.1 Support for Both 8-bit and 10-bit Input Data
The GF9331 supports 8-bit and 10-bit input data. When operating with 8-bit input
data, the two LSBs of the GF9331’s 10-bit input bus should be set LOW and the
input data applied to the 8 MSBs of the input bus.
3.2.2 Generic Input Format Signalling
T
he GF9331 supports generic input data formats with either 4:1:1 or 4:2:2 sampling
structures that require up to 2046 active samples per line and have maximum total line
width of 4096 (active + blanking) samples. In addition, there is a limit of 2048 lines per
interlaced frame. The following host interface parameters are programmable to
describe the generic input data format relative to the F_IN, V_IN and H_IN signals.

11111
Generic HD input data format with 4:2:2 sampling and a separate Y/C format. Y Data applied to Y_IN. Cb Cr
data applied to C_IN. The externally supplied F_IN, V_IN and H_IN signals are used to synchronize the input data
stream.
NOTE: Input clock is 74.25MHz or 74.25/1.00MHz.
