Semtech GN2003S

9.95 - 11.3 Gb/s Limiting Amplifier plus Clock and Data Recovery

The GN2003S is a second generation Limiting Amplifier plus CDR device. This device features Gennum's ClearEdge™ technology offering best-in-class eye quality.

Key improvements from the first generation device include significant reduction in power consumption, increased Input Jitter Tolerance and reduced Jitter Peaking.

The on-chip Limiting Amplifier offers best-in-class SRS performance, eliminating the need for a stand-alone Limiting Amplifier in optical modules.

The SRS performance combined with excellent IJT and low power consumption makes this device suitable as a high performance Limiting Amplifier with CDR for XFP, X2, XPAK, XENPAK and 300-pin Transceiver Modules.

Together with Gennum's line of 10Gb/s TIAs, excellent Stressed Eye Sensitivity performance is achieved at the module level.

The GN2003S device is packaged in a small outline 4mm × 4mm 24-pin, high-frequency QFN, lead-free and green package with exposed pad.
