GN2004SCNE3

Overview

The GN2004SCNE3 is a four-channel, low-power Clock and Data Recovery (CDR) retimer designed for high-speed serial data applications. It supports data rates ranging from 1.0625 Gbps to 12.5 Gbps per channel, making it suitable for multi-rate optical transceivers and backplane interconnects. The device integrates adjustable continuous-time linear equalization (CTLE) to compensate for channel loss exceeding 30 dB. It operates on a single 1.8V supply with a total power consumption of approximately 700 mW. The component is housed in a compact 3.5mm x 5.5mm CSP package, facilitating integration into space-constrained modules such as QSFP+ and SFP+ form factors.

Feature Summary

• Four independent channels supporting data rates from 1.0625 Gbps to 12.5 Gbps
• Integrated Continuous-Time Linear Equalizer (CTLE) for channel loss compensation up to 30 dB
• Low power consumption of approximately 700 mW total across all channels
• Compact 3.5mm x 5.5mm CSP package with RoHS compliance

Applications

• Multi-rate optical transceiver modules (QSFP+, SFP+)
• Backplane interconnect systems requiring signal regeneration
• High-speed serial communication links with significant insertion loss

Part Context

The GN2004SCNE3 belongs to Semtech's ClearEdge family of CDR devices. This series focuses on providing low-jitter clock recovery and signal conditioning for next-generation data center and telecommunications infrastructure. The 'SC' suffix typically denotes the specific package type and temperature range, while 'NE3' indicates lead-free and RoHS compliant manufacturing processes.
