GS2962数据手册集成电路（IC）的视频处理规格书PDF

描述 Description

The GS2962 is an SDI transmitter, generating a SMPTE 424M, SMPTE 292M, SMPTE 259M-C or DVB-ASI compliant serial digital output signal.
 
The integrated ClockCleaner™ allows the device to accept parallel clocks with high input jitter, and still provide a SMPTE compliant serial digital output.
The device can operate in four basic user selectable modes: SMPTE mode, DVB-ASI mode, Data-Through mode, or Standby mode.
In SMPTE mode, the GS2962 performs all SMPTE processing features. Both SMPTE 425M Level A and Level B formats are supported with optional conversion from Level A to Level B for 1080p 50/60 4:2:2 10-bit.
In DVB-ASI mode, the device will perform 8b/10b encoding prior to transmission.
In Data-Through mode, all SMPTE and DVB-ASI processing is disabled. The device can be used as a simple parallel to serial converter.
The device can also operate in a lower power Standby mode. In this mode, no signal is generated at the output.
The GS2962 includes a fully SMPTE-compliant cable driver for SMPTE 259M-C, SMPTE 292M and SMPTE 424M interfaces. It features automatic dual slew-rate selection, depending on 3G-, HD- or SD-SDI operational requirements.
