Semtech GN2406

The Gennum® 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 - 11.3Gbps. To enable backward compatibility with legacy data rates, half rate (5Gbps) and quarter rate (2.5Gbps) 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.
