M21250/M21251/M21252

Quad-Channel CDR/Reclocker (42 Mbps - 3.2 Gbps)

The M21250, M21251, and M21252 (M2125x) devices are high-performance quad channel retimers optimized for

telecom, datacom, and digital video applications. Each channel of the CDR/reclocker array includes an

independent multi-rate CDR/reclocker, allowing maximum flexibility in system design. Signal conditioning features

of the M2125x include input equalization and output pre-emphasis to compensate for lossy PCB traces and

backplane connectors. A built-in frequency synthesizer allows each channel of the device to operate at a different

data rate simultaneously while operating from a single reference clock. The M2125x can be controlled through

hardwired pins or via a 2-wire or 4-wire serial programming interface. The serial programming interface allows

users to have complete control of the device features. The M2125x devices support JTAG external boundary scan

which includes all of the high-speed I/O as well as the digital I/O.

Features

• Four independent CDR/reclockers (CDR/RCLKs) SMPTE, DVB-ASI

compliant

• Integrated loop filter and terminations

• Serial control or hardwired control, JTAG boundary scan

• Low power consumption of 400 mW (1 channel active)

• Built-in pattern generator and receiver with JTAG support for

module and system testing (PRBS, 8b/10b, Fibre Channel, User

Programmable patterns)

• User Selectable Input Equalization and Pre-Emphasis for backplane

ISI reduction

• Multirate support (42 Mbps - 3.2 Gbps)

• Differential outputs for recovered clock and retimed data
