Semtech GN1159

1.0 to 12.5Gb/s multi-rate LR transceiver chip with digital diagnostics

Add to Watch List

GN1159 is a multi-rate transceiver IC designed specifically for datacom and telecom applications. The transmit DFB/FP laser driver has an advanced design that is focused on delivering excellent optical performance while still achieving low power. Programmable equalization is available to optimise jitter. The Tx output has programmable rise/fall times to allow optimization for different bit rates. GN1159 features an integrated automatic power control loop that adjusts bias current to compensate for laser aging and environment change. GN1159 includes a receive post amplifier and a full suite of flexible digital diagnostic features that eliminate the need for external microprocessor.
