GS9020

The GS9020 is specifically designed to deserialize SMPTE 259M serial digital signals. The inclusion of Error Detection and Handling (EDH) ensures the integrity of the data being received from the serial digital interface (SDI). Internal 75Ω termination resistors allow INTERLINX™ seamless connection with the GS9035 Reclocker or the GS9025 eceiver, thus providing a complete, high performance, digital video input processor with EDH, digital sync signal generation, and other system features.

The GS9020 also includes a parallel to serial converter and NRZI scrambler to provide re-serialized, EDH compliant data output. The EDH core implements EDH insertion and extraction according to SMPTE RP-165. This core also generates noise immune timing signals such as horizontal sync, vertical blanking, field ID and ancillary data identification. It also provides many system features such as a FIFO reset pulse (which can be programmed to coincide with either EAV or SAV), TRS-ID and ANC header cor rection, user controlled output blanking and ITU-R-601 output clipping. The GS9020 has an I²C (Inter-Integrated Circuit, I²C is a registered Trademark of Philips) serial interface bus and an 8-bit parallel port for external access to all error flags and device configuration bits.
