Quad 10Gb/s CDR with Transmit De-Emphasis

Overview

The GN2406 is a quad repeater/re-timer device designed to enhance the reach and robustness of high speed serial links by compensating for transmission losses and re-setting the crosstalk and jitter budget.
The GN2406 features Gennum’s proven reference-free CDR architecture which simplifies system design and reduces overall cost. Each channel supports independent locking to data rates from 9.95 - 11.3Gb/s. To enable backward compatibility with legacy data rates, half rate (5Gb/s) and quarter rate (2.5Gb/s) operation is also supported. Other rates can be supported using the re-timer bypass feature.
High sensitivity limiting amplifiers at the input make this device suitable for use in optical modules. Gennum’s proprietary CLEAREDGE™ technology ensures extremely low output jitter. Copper cable or backplane trace losses of up to 28dB can be compensated using the output de-emphasis capability.
