GS1662 HD/SD-SDI Serializer with Complete SMPTE Video Support The integrated ClockCleaner allows the device to accept Key Features parallel clocks with greater than 300ps input jitter and still Operation at 1.485Gb/s, 1.485/1.001Gb/s and 270Mb/s provide a SMPTE compliant serial digital output. Supports SMPTE ST 292, SMPTE ST 259-C and DVB-ASI The device can operate in four basic user selectable modes: Integrated Cable Driver SMPTE mode, DVB-ASI mode, Data-Through mode, or Integrated, low-noise VCO Standby mode. Integrated ClockCleaner In SMPTE mode, the GS1662 performs SMPTE scrambling Ancillary data insertion and NRZ to NRZI coding. In addition, the device can insert Parallel data bus selectable as either 20-bit or 10-bit TRS words, calculate and insert line numbers and line SMPTE video processing including TRS calculation and based CRC s, re-map illegal code words, map 8-bit TRS to insertion, line number calculation and insertion, line 10-bit TRS, calculate and insert EDH CRC s and flags, and based CRC calculation and insertion, illegal code insert SMPTE ST 352 payload identifier packets. All of the re-mapping, SMPTE ST 352 payload identifier processing features are optional, and may be disabled via generation and insertion external control pins and/or via the Host Interface. GSPI host interface The GS1662 provides ancillary data insertion in SMPTE +1.2V digital core power supply, +1.2V and +3.3V mode as well. The entire ancillary packet is programmed analog power supplies, and selectable +1.8V or +3.3V into internal registers through the GSPI Host Interface, I/O power supply including the Ancillary Data Flag (ADF), Data Identification words (DID and SDID) and checksum. The GS1662 then -20C to +85C operating temperature range recalculates the checksum and inserts the complete Low power operation (typically at 330mW, including ancillary packet into the video stream. Cable Driver) In DVB-ASI mode, the device will perform 8b/10b encoding Small 11mm x 11mm 100-ball BGA package prior to transmission. Pb-free and RoHS compliant In Data-Through mode, all SMPTE and DVB-ASI processing Applications is disabled, and the device can be used as a simple parallel to serial converter. Application: Single Link (3G-SDI) to Dual Link (HD-SDI) Converter The device can also operate in a lower power Standby mode. In this mode, no signal is generated at the output. 10-bit HD-SDI GS1662 Parallel data inputs must be provided in 20-bit or 10-bit Link A HVF/PCLK Semtech 3G-SDI multiplexed format for HD and SD video rates. The GS2960 EQ HVF/PCLK associated Parallel Clock input signal operates at 148.5 or 10-bit HD-SDI GS1662 Link B 148.5/1.001MHz (HD 10-bit multiplexed format), 74.25 or 74.25/1.001MHz (for HD 20-bit format), 27MHz (for SD 10-bit format) and 13.5MHz (for SD 20-bit format). Description The GS1662 is a complete SDI Transmitter, generating a The GS1662 includes an integrated Cable Driver fully SMPTE ST 292, SMPTE ST 259-C or DVB-ASI compliant compliant with SMPTE ST 259-C and SMPTE ST 292. It serial digital output signal. features automatic dual slew-rate selection, depending on HD or SD operational requirements.
