DESCRIPTION

· The M21050 is a high-performance duplex quad (octal) multi-rate clock and data recovery (CDR) array, optimized for multi-lane telecom and datacom applications.

· Each CDR operates independently at bit rates between 1.0 Gbps to 3.2 Gbps, providing maximum flexibility in system design.

· Features include adaptive input equalization and output pre-emphasis for robust signal reception and transmission up to 60".

· Supports AC-coupled input to CML and Infiniband, and DC-coupled or AC-coupled outputs.

· Frequency acquisition is achieved with an external reference clock, and the built-in frequency synthesizer enables multi-rate operation with a single reference clock.

· Device control is available through hardwired pins or an I2C-compatible interface.

FEATURES

· Eight independent multi-rate CDRs operating between 1.0 Gbps-3.2 Gbps in a duplex quad configuration.

· Integrated adaptive equalization for improved link performance with lower cost board materials.

· Integrated pre-emphasis for driving trace lengths up to 60".

· AC-coupled input interface to CML and Infiniband.

· Flexible control via I2C-compatible interface or hardwired pins.

· Power consumption of 780 mW.

· Built-in pattern generator and receiver for module and system testing.

· Optimized for PRBS- or 8b/10b-like data patterns.

APPLICATIONS

· Multi-lane telecom and datacom applications.

· Systems requiring robust signal reception and transmission over long trace lengths.

· Applications needing flexible control options and multi-rate operation.

· Module and system testing with built-in pattern generator and receiver.
