Semtech GN2405A

Quad 10Gb/s CDR with Rx Equalizer and Transmit De-Emphasis

Add to Watch List

The GN2405A 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 GN2405A 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.

The GN2405A can be used in multiple applications. It can be used as a CDR in parallel optical modules or in active copper cable assemblies. It’s flexible de-emphasis driver and jitter performance are ideal for use as a line card or backplane repeater.

Features
