CONTROL SIGNAL/OPERATING MODE SUMMARY
SYNC
The SYNC control signal provides synchronization for the internal 4:2:2 de-multiplexer. SYNC should be held high on clock
period N and low on clock period N+1 when the first C
B
sample is presented to the SI
9..0
inputs. SYNC may be held low until
re-synchronization is desired or may be toggled at every occurrence of a C
B
sample.
SELECT_MATRIX AND SETUP
SELECT_MATRIX and SETUP select the color space conversion and offset insertions which the GF9103 is to perform. The
following chart presents the available color space conversions and the corresponding states of the SELECT_MATRIX and
SETUP control pins. SETUP is a dynamic pin that may be modified every clock cycle.
