General Description

The MAX3875 is a compact, low-power clock recovery and data retiming IC for 2.488Gbps SDH/SONET applications. The fully integrated phase-locked loop recovers a synchronous clock signal from the serial NRZ data input, which is retimed by the recovered clock.

Features

♦ Exceeds ANSI, ITU, and Bellcore SONET/SDH Regenerator Specifications

♦ 400mW Power Dissipation (at +3.3V)

♦ Clock Jitter Generation: 0.003UIRMS

♦ Single +3.3V or +5V Power Supply

♦ Fully Integrated Clock Recovery and Data Retiming

♦ Additional High-Speed Input Facilitates System Loopback Diagnostic Testing

♦ Tolerates >2000 Consecutive Identical Digits

♦ Loss-of-Lock Indicator

♦ Differential PECL-Compatible Data and Clock Outputs
