Log/Limiting Amplifiers

ADI’s high gain limiting amp ICs are optimized for SFP/SFF/GBIC datacom and telecom optical transceiver modules and provide the receiver functions of quantization and Loss of Signal Detection as well as SFF-8472 compliant average power measurement. Applications include 1x2x4x Fibre Channel, 10GBASE-LX4, multi-rate SONET/SDH OC3 to OC48 FEC and GbE. ADI’s high gain limiting amps feature: low power; excellent sensitivity and jitter performance.

Circuit from the lab Engineered. Tested. Ready to Integrate.
