Video Processor HVF/PCLK Storage: The integrated Narrow BW PLL allows the device to accept Tape/HDD/Solid State AUDIO 1/ 2 3G-SDI GS2972 AUDIO 3/ 4 parallel clocks with high input jitter, and still provide a AUDIO 5/ 6 Audio Processor AUDIO 7/ 8 SMPTE compliant serial digital output. Audio Clocks The device can operate in four basic user selectable modes: Sync Analog GS4911 Audio Inputs Seperator Sync SMPTE mode, DVB-ASI mode, Data-Through mode, or XTAL Standby mode. In SMPTE mode, the GS2972 performs all SMPTE processing Application: Multi-format Presentation Switcher features. Both SMPTE ST 425 Level A and Level B formats (Output Stage) are supported with optional conversion from Level A to Program AE S In P rogram AE S Out P reset AE S In Audio P review AE S Out Level B for 1080p 50/60 4:2:2 10-bit.

The device can be used as a simple parallel to GS2972 serial converter. Key/Fill Image Inputs Store The device can also operate in a lower power Standby Analog Sync mode. In this mode, no signal is generated at the output. Sync Clock & GS4911 Seperator Sync Distribution The GS2972 integrates a fully SMPTE-compliant Cable XTAL Driver for SMPTE ST 259-C, SMPTE ST 292 and SMPTE ST 424 interfaces. It features automatic dual Application: 3Gb/s SDI Test Signal Generator slew-rate selection, depending on 3Gb/s or HD or SD Memory XTAL operational requirements. Analog Sync 20-bit Video Sync HVF/PCLK GS4911 Signal HVF/PCLK Seperator In accordance with SMPTE ST 272 and SMPTE ST 299, up to Generator 3G-SDI GS2972 eight channels (two audio groups) of serial digital audio AES 1/2 AES 3/4 Audio Clocks Audio AES 5/6 may be embedded into the video data stream.The input Generator AES 7/8 audio signal formats supported by the device include 2 AES/EBU, I S and serial audio. 16, 20 and 24-bit audio formats are supported at 48kHz synchronous for SD modes and 48kHz synchronous or asynchronous in HD, 3Gb/s modes.
