TM GS1572 Multi-Rate Serializer with Cable Driver and ClockCleaner Key Features Description HD-SDI, SD-SDI, DVB-ASI transmitter The GS1572 is the next generation multi-standard serializer with an integrated cable driver. The device Integrated SMPTE 292M and 259M-C compliant cable provides robust parallel to serial conversion, generating a driver SMPTE 292M/259M-C compliant serial digital output Integrated ClockCleaner signal. The integrated cable driver features an output User selectable video processing features, including: disable (high-impedance) mode and an adjustable signal swing. Data input is accepted in 20-bit parallel format or Generic ancillary data insertion 10-bit parallel format. An associated parallel clock input Support for HVF or EIA/CEA-861 timing input must be provided at the appropriate operating frequency - Automatic standard detection and indication 74.25/74.1758/13.5MHz (20-bit mode) or Enhanced SMPTE 352M payload identifier 148.5/148.352/27MHz (10-bit mode). generation and insertion The GS1572 features an internal PLL which, if desired, can TRS, CRC, ANC data checksum, and line number be configured for a loop bandwidth below 100kHz. When calculation and insertion used in conjunction with the GO1555 Voltage Controlled EDH packet generation and insertion Oscillator, the GS1572 can tolerate well in excess of 300ps jitter on the input PCLK and still provide output jitter within Illegal code remapping SMPTE specifications. SMPTE 292M and SMPTE 259M-C compliant In addition to serializing the input, the GS1572 performs scrambling and NRZ NRZI encoding NRZ-to-NRZI encoding and scrambling as per SMPTE Blanking of input HANC and VANC space 292M/259M-C when operating in SMPTE mode. When JTAG test interface operating in DVB-ASI mode, the device will insert K28.5 1.8V core and 3.3V charge pump power supply sync characters and 8b/10b encode the data prior to 1.8V and 3.3V digital I/O support serialization. The device also provides a range of other data processing functions. All processing features are optional Low power standby mode and may be enabled/disabled via external control pin(s) o o Operating temperature range: -20 C to +85 C and/or host interface programming. Pb-free, RoHS compliant, 11mm x 11mm 100-ball BGA Typical power consumption, including the GO1555 VCO, is package 440mW. The standby feature allows the power to be reduced to 125mW. Power may be reduced to less than Applications 10mW by also removing the power to the cable driver and SMPTE 292M and SMPTE 259M-C Serial Digital eliminating transitions at the parallel data and clock inputs. Interfaces The GS1572 is Pb-free and RoHS compliant.
