ONET1130EC-EVM 11.7-Gbps transceiver with dual CDRs and modulator driver
ONET1130EC-EVM 11.7-Gbps transceiver with dual CDRs and modulator user’s guide
This document describes the main features and functionality of the evaluation module (EVM) board for the part numbers ONET1130EC and ONET1130EP.
The ONET1130EC and ONET1130EP are 11.7-Gbps transceivers with integrated limiting amplifier and modulator driver. The ONET1130EC includes dual CDRs and the ONET1130EP does not.
The EVM can be used to evaluate the performance of the parts in conjunction with an electroabsorptive modulated laser (EML) transmit optical subassembly (TOSA) and a receive optical subassembly (ROSA) in standard XMD compliant packages.
The EVM is controlled with USB2ANY graphic user interface (GUI). This software can be downloaded at www.ti.com.
