DETAILED DEVICE DESCRIPTION
1. SUPPORTED INPUT VIDEO FORMATS
The GF9330 supports multiple input data formats with
multiplexed or separate Y/C channels. Data is supplied to
the GF9330 through the Y_IN[9:0] and the C_IN[9:0]
busses. Table 1 outlines the data formats that are
supported according to the setting of the control register
bits STD[4:0]
Note: For all progressive video standards the GF9330 must
be manually set to bypass mode (MODE[2:0] = 111). See
Section 5 for details.
