M844, MULTI-RATE CLOCK RECOVERY

The M844 Multi-Rate Clock Recovery module provides low jitter clock recovery from NRZ or RZ input data formats.

Four data rates are digitally selectable: 9.953, 10.3125, 10.664, or 10.709Gb/s.

Incoming data is first amplified by a limiting amplifier.

The data is then both: a) provided as the module’
