DESCRIPTION
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 Receiver, thus providing a complete, high performance, digital video input processor with EDH, digital sync signal generation, and other system features.
FEATURES
• fully compatible with SMPTE 259M
• auto-standard operation to 540MHz
• embedded EDH and data processing core
• selectable loop through or re-serialized EDHprocessed serial output
• noise immune HVF timing signal outputs
• configurable FIFO reset pulse for clearing downstream FIFOs
• ANC header and TRS-ID correction for all standards
• user controlled output blanking
• ITU-R-601 output clipping for active picture area
• ancillary data indication
• low system power
• selectable I²C interface or 8-bit parallel port for access to EDH flags and device configuration bits
• EDH flags also available on dedicated pins
• seamless flag mapping to GS9021 EDH coprocessor
• 80 pin LQFP
APPLICATIONS
SMPTE 259M serial digital receiver for composite and component standards including 4:4:4:4 at 540Mb/s with EDH processing; Noise immune digital sync and timing generation; Cost effective EDH insertion and checking for serial routing and distribution applications.
