M21315
HD/SD-SDI Reclocker w/ Integrated Rate Detection
Description
The M21315 is a high-speed, low-power reclocker designed to remove both random and inter-symbol interference (ISI) jitter from the input data for SMPTE and DVB-ASI serial digital video applications. Mindspeed's high-performance reclocker offers significant power reduction compared to legacy reclocking solutions. The M21315 is based on a custom and proprietary reclocker core. The high-performance reclocker design results in high-jitter tolerance, especially in the presence of duty-cycle-distortion (DCD) that typically arises with AC coupling and video pathological test patterns. The M21315 also offers improved auto rate detect acquisition times over legacy reclocker solutions. The M21315 supports SMPTE HD/SD-SDI data rates from 143 Mbps to 1485 Mbps. The M21315 is functionally and pin compatible with the GS1575B (without serial clock out and loss of signal indicators). The M21315 occupies the same footprint as the GS9075B (without serial clock out and loss of signal indicator). The M21315 also consumes less power than the GS1575B or GS9075B.
