SY88973BL中文资料麦瑞半导体数据手册PDF规格书

General Description

The SY88973BL low-power, limiting post amplifier is designed for use in fiber optic receivers. The device connects to typical transimpedance amplifiers (TIAs). The linear signal output from TIAs can contain significant amounts of noise and may vary in amplitude over time. The SY88973BL quantizes these signals and outputs typically 800mVPP voltage-limited waveforms.
