Product Detail

M21251
HD/SDI-SDI Quad Reclocker w/ External Rate Detection
For new designs, please see M21250) The M21251 is a high-performance quad multi-rate clock and data recovery (CDR)array, optimized for multi-lane video, telecom and datacom applications. Each CDR operates independently at bit rates between 42 Mbps to 1.6 Gbps, allowing maximum flexibility in system design. Signal conditioning features include adaptive input equalization and output pre-emphasis, allowing robust reception and transmission of signals to other devices up to 60" away.
Features
  • Integrated signal conditioning for improved signal integrity with inexpensive PCB materials for longer PCB trace lengths:
  • Fully independent, quad channel multi-rate video reclockers, SMPTE and DVB-ASI compliant: 42 Mbps to 1600 Mbps
  • BIST features for PCB and system testing with fully independent transmitter and receiver: PRBS : 27 -1, 215 -1, 223 -1, 231 -1, 8b/10 : CJTPAT, CRPAT, countdown
  • PCB layout friendly with 'pass through' I/O and high speed output polarity inversion
  • Serial SPI 4 wire interface or hardwired interface control
  • Flexible I/O interfacing to CML, LVDS, and LVPECL with per channel output amplitude control
  • Integrated loop filter components and I/O termination resistors for simplified PCB designs and reduced cost
  • Superior jitter generation (5mUI typical) and improved jitter tolerance in the high frequency band
  • Very low power dissipation and flexible power supply support for reduced power supply and thermal management costs
  • Output pre-emphasis Up to 40° with FR4 at 3.2 Gbps
  • Input equalization : Up to 60° with FR4 at 3.2 Gbps
