GS1582 Multi-Rate Serializer with Cable Driver, Audio Multiplexer and TM ClockCleaner DVB-ASI Serial Digital Interfaces Key Features HD-SDI, SD-SDI, DVB-ASI transmitter with audio Description embedding The GS1582 is the next generation multi-standard Integrated SMPTE 292M and 259M-C compliant cable serializer with an integrated cable driver. The device driver provides robust parallel to serial conversion, generating a Integrated ClockCleaner SMPTE 292M/259M-C compliant serial digital output User selectable video processing features, including: signal. The integrated cable driver features an output disable (high impedance) mode and an adjustable signal Generic ancillary data insertion swing. Data input is accepted in 20-bit parallel format or Support for HVF or EIA/CEA-861 timing input 10-bit parallel format. An associated parallel clock input Automatic standard detection and indication must be provided at the appropriate operating frequency Enhanced SMPTE 352M payload identifier 74.25/74.1758/13.5MHz (20-bit mode) or generation and insertion 148.5/148.352/27MHz (10-bit mode). TRS, CRC, ANC data checksum, and line number The GS1582 features an internal PLL which, if desired, can calculation and insertion be configured for a loop bandwidth below 100kHz. When EDH packet generation and insertion used in conjunction with the GO1555 Voltage Controlled Oscillator, the GS1582 can tolerate well in excess of 300ps Illegal code remapping jitter on the input PCLK and still provide output jitter within SMPTE 292M and SMPTE 259M-C compliant SMPTE specifications. scrambling and NRZ NRZI encoding In addition to serializing the input, the GS1582 performs Blanking of input HANC and VANC space NRZ-to-NRZI encoding and scrambling as per SMPTE User selectable audio processing features, including: 292M/259M-C when operating in SMPTE mode. When SMPTE 299M and SMPTE 272M-A/C compliant operating in DVB-ASI mode, the device will insert K28.5 audio embedding sync characters and 8b/10b encode the data prior to serialization. The device also provides a range of other data Support for up to 8 channels processing functions. All processing features are optional Support for audio group replacement and may be enabled/disabled via external control pin(s) JTAG test interface and/or host interface programming. 1.8V core and 3.3V charge pump power supply The GS1582 can embed up to 8 channels of audio into the 1.8V and 3.3V digital I/O support video data stream in accordance with SMPTE 299M and Low power standby mode SMPTE 272M. The audio input signal formats supported by 2 the device include AES/EBU and I S serial digital formats o o Operating temperature range: -20 C to +85 C with a 16, 20 or 24 bit sample size and a 48 kHz sample rate. Pb-free, RoHS compliant, 11mm x 11mm 100-ball BGA Additional audio processing features include individual package channel enable, channel swap, group swap, ECC generation and audio channel status insertion. Applications Typical power consumption, including the GO1555 VCO, is SMPTE 292M and SMPTE 259M-C Serial Digital 500mW. The standby feature allows the power to be Interfaces reduced to 125mW.
