1 / 82 page  1 of 82 GS2962 3G/HD/SD-SDI Serializer with Complete SMPTE Video Support Data Sheet 48005 - 7 October 2010 GS2962 3G/HD/SD-SDI Serializer with Complete SMPTE Video Support www.gennum.com Key Features • Operation at 2.970Gb/s, 2.970/1.001Gb/s, 1.485Gb/s, 1.485/1.001Gb/s and 270Mb/s • Supports SMPTE 425M (Level A and Level B), SMPTE 424M, SMPTE 292, SMPTE 259M-C and DVB-ASI • Integrated Cable Driver • Integrated, low noise VCO • Integrated Narrow-Bandwidth PLL • Ancillary data insertion • Optional conversion from SMPTE 425M Level A to Level B for 1080p 50/60 4:2:2 10-bit • Parallel data bus selectable as either 20-bit or 10-bit • SMPTE video processing including TRS calculation and insertion, line number calculation and insertion, line based CRC calculation and insertion, illegal code re-mapping, SMPTE 352M payload identifier generation and insertion •GSPI host interface • 1.2V digital core power supply, 1.2V and 3.3V analog power supplies, and selectable 1.8V or 3.3V I/O power supply • -20ºC to +85ºC operating temperature range • Low power operation (typically at 400mW, including Cable Driver) • Small 11mm x 11mm 100-ball BGA package • Pb-free and RoHS compliant Applications Description The GS2962 is a complete SDI Transmitter, generating a SMPTE 424M, SMPTE 292, SMPTE 259M-C or DVB-ASI compliant serial digital output signal. The integrated narrow-BW PLL 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 integrates a fully SMPTE-compliant Cable Driver for SMPTE 259M-C, SMPTE 292 and SMPTE 424M interfaces. It features automatic dual slew-rate selection, depending on 3Gb/s or HD or SD operational requirements.
