GENERAL DESCRIPTION
The KGL4142KD is a high performance automatic gain control amplifier for SONET/SDH and 10GbE
applications up to 11.3Gb/s,especially using EDC. The device has wide gain control range : -10dB to 28dB.
The KGL4142KD data input accepts single ended AC-coupled or differential AC-coupled signals, and require
external blocking capacitors. The output interface of KGL4142KD is differential AC-coupled, and require external
blocking capacitors.
The KGL4142KD can be controlled gain by varying Vagc.
The KGL4142KD is packaged in a small 24-pin QFN Package : 4x4mm
