Product Summary

The gs1672 is a HD/SD-SDI serializer, generating a SMPTE 292, SMPTE 259M-C or DVB-ASI compliant serial digital output signal. The integrated Narrow BW PLL allows the device to accept parallel clocks with high input jitter, and still provide a SMPTE compliant serial digital output. The application of the gs1672 includes 1080p 30 Camera/Camcorder.
