DATA SHEET
FEATURES
DESCRIPTION
The GS9001 implements error detection and handling (EDH)
functions according to SMPTE RP165. Interfacing to the
parallel port of either the GS9002/GS9022 serial digital
encoders or GS9000 decoder, the GS9001 provides EDH
insertion and extraction for 4ƒsc NTSC, 4ƒsc PAL and 4:2:2
component standards up to 18 MHz luminance sampling.
The GS9001 also generates timing signals such as horizontal
sync, vertical blanking, field ID and ancillary data identification.
The ancillary data identification aids the extraction of ancillary
data from the data stream.

The device has an
I
2
C (Inter-Integrated Circuit) serial interface
bus for communication with a microcontroller. The device
can be programmed as an
I
2
C slave transmitter or receiver by
the microcontroller. This interface can be used to read the
complete set of error flags and override the flag status prior to
re-transmission. The device automatically determines the
operating standard which can be overridden through the
I
2
C
interface. Timing signals and transmission error flags are also
available on dedicated outputs.
