GF9331 Data Sheet
3. Detailed Device Description
3.1 Input Data Formats
The GF9331 supports multiple input data formats with multiplexed or separate Y/C
channels. Data is supplied to the GF9331 through the Y_IN[9:0] and the C_IN[9:0]
busses. Table 3-1: Encoding of STD[4:0] for Selecting Input Data Format outlines
the data formats that the GF9331 supports according to the setting of STD[4:0] pins
or host interface bits, STD[4:0].
NOTE: For all progressive video standards the GF9331 must be manually set to
bypass mode (MODE=0, pin or register). See Host Interface for host interface
details.
