DESCRIPTION

· The GS9001 EDH Coprocessor implements error detection and handling (EDH) functions in compliance with SMPTE RP165.

· It interfaces with the parallel port of GS9002/GS9022 serial digital encoders or GS9000 decoder, providing EDH insertion and extraction for 4ƒsc NTSC, 4ƒsc PAL, and 4:2:2 component standards up to 18 MHz luminance sampling.

· The device generates essential timing signals such as horizontal sync, vertical blanking, field ID, and ancillary data identification, facilitating ancillary data extraction from the data stream.

· It features an I2C serial interface bus for microcontroller communication, allowing the device to be programmed as an I2C slave transmitter or receiver.

· The I2C interface enables reading the complete set of error flags and overriding the flag status prior to re-transmission, with automatic operating standard determination that can be overridden via the I2C interface.

· Timing signals and transmission error flags are available on dedicated outputs.

FEATURES

· Supports 4ƒsc, 4:2:2, and 360 Mb/s serial digital interfaces.

· Suitable for source and destination equipment, distribution equipment, and test equipment.

· EDH insertion and extraction in a single device.

· Autostandard operation with I2C serial communications interface for error flags and device configuration access.

· Available in standalone mode with error flags on dedicated outputs.

· Generates field, vertical, horizontal timing signals, ancillary data indication, and TRS indication.

· Provides video standard and invalid data indication.

· Features a 21-bit Errored Fields counter and passthrough mode to bypass EDH packet insertion.

· True 8-bit compatibility with a 40 MHz operating frequency.

· Pb-free and Green compliant.

APPLICATIONS

· Error detection and handling in video processing systems.

· Integration with serial digital encoders and decoders for enhanced error management.

· Utilization in broadcast and professional video equipment for reliable signal integrity.

· Application in test and measurement setups for video signal analysis.

· Deployment in distribution systems for maintaining video quality across networks.
