www.DataSheet4U.com GS1531 HD-LINX™ II Multi-Rate Serializer GS1531 Data Sheet Key Features SMPTE 292M and SMPTE 259M-C compliant scrambling and NRZ → NRZI encoding (with bypass) DVB-ASI sync word insertion and 8b/10b encoding Superior rejection of jitter on input PCLK user selectable additional processing features including: CRC, ANC data checksum, and line number calculation and insertion TRS and EDH packet generation and insertion illegal code remapping Description The GS1531 is a multi-standard serializer with an integrated cable driver. When used in conjunction with the GO1525 Voltage Controlled Oscillator, a transmit solution can be realized for HD-SDI, SD-SDI and DVB-ASI applications. The device features an internal PLL, which can be configured for loop bandwidth as narrow as 100kHz. Thus the GS1531 can tolerate substantive jitter on the input PCLK and still provide output jitter well within SMPTE specification. Connect the output clocks from Gennum’s GS4911 clock generator directly to the GS1531’s PCLK input and configure the GS1531’s loop bandwidth accordingly. In addition to serializing the input, the GS1531 performs NRZ-to-NRZI encoding and scrambling as per SMPTE 292M/259M-C when operating in SMPTE mode. When operating in DVB-ASI mode, the device will insert K28.5 sync characters and 8b/10b encode the data prior to serialization. Parallel data inputs are provided for 10-bit multiplexed or 20-bit demultiplexed formats at both HD and SD si...
