GS9001

Interfacing to the parallel port of either the GS9002/GS9022 serial digital encoders or GS9000 decoder, the GS9001 provides EDH insertion and extraction for 4fsc NTSC, 4fsc 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 andancillary data identification. The ancillary data identification aids the extraction of ancillary data from the data stream.

The device has an I2C (Inter-Integrated Circuit) serial interface bus for communication with a microcontroller. The device can be programmed as an I2C 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 I2C interface. Timing signals and transmission error flags are also available on dedicated outputs.
