The device provides robust parallel to serial conversion, generating a SMPTE 292M/259M-C compliant serial digital output signal. The integrated cable driver features an output disable (high impedance) mode and an adjustable signal swing. Data input is accepted in 20-bit parallel format or 10-bit parallel format. An associated parallel clock input must be provided at the appropriate operating frequency; 74.25/74.1758/13.5MHz (20-bit mode) or 148.5/148.352/27MHz (10-bit mode). The GS1582 features an internal PLL which, if desired, can be configured for a loop bandwidth below 100kHz. When used in conjunction with the GO1555 Voltage Controlled Oscillator, the GS1582 can tolerate well in excess of 300ps jitter on the input PCLK and still provide output jitter within SMPTE specifications. In addition to serializing the input, the GS1582 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. The device also provides a range of other data processing functions. All processing features are optional and may be enabled/disabled via external control pin(s) and/or host interface programming. The GS1582 can embed up to 8 channels of audio into the video data stream in accordance with SMPTE 299M and SMPTE 272M. The audio input signal formats supported by the device include AES/EBU and I2S serial digital formats with a 16, 20 or 24 bit sample size and a 48 kHz sample rate. Additional audio processing features include individual channel enable, channel swap, group swap, ECC generation and audio channel status insertion. Typical power consumption, including the GO1555 VCO, is 500mW. The standby feature allows the power to be reduced to 125mW. Power may be reduced to less than GS1582 Multi-Rate Serializer with Cable Driver, Audio Multiplexer and ClockCleanerTM www.gennum.com Data Sheet 40117 - 4 December 2011 1 of 115 10mW by also removing the power to the cable driver and The GS1582 is Pb-free and RoHS compliant. eliminating transitions at the parallel data and clock inputs.
