GN2405AINE3 Description

Short technical summary and product information.

The Semtech GN2405AINE3 is a versatile quad repeater/re-timer device designed to enhance high-speed serial links. It compensates for transmission losses and resets jitter budgets, supporting data rates from 9.95Gb/s to 11.3Gb/s. The device also features automatic rate detection for quarter (2.5Gb/s) and half (5Gb/s) rate modes, with a retimer bypass option up to 11.3Gb/s.

 

Key electrical features include low output jitter, high input jitter tolerance (better than 0.7 UI), and programmable differential output voltage ranging from 400mV to 800mV. It offers independent channel operation and de-emphasis up to 28dB to compensate for signal loss. The GN2405AINE3 utilizes an I2C control interface and automatically loads configuration data from EEPROM. It includes loss of signal detect with adjustable thresholds and operates from a single 3.3V supply.

 

This IC is suitable for applications such as optical modules and active copper cable assemblies for InfiniBand and Ethernet, as well as retimers on line cards for QSFP, parallel optical, and SFP+ modules. It is housed in a compact 7x7mm, 48-pin QFN package, designed for surface mounting.
