Description
The GS1582 is the next generation multi-standard serializer with an integrated cable driver. 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).
