Microchip Technology, Inc. Special Purpose Amplifiers SY88343HLMG

The SY88343HLMG is a low-power, high-sensitivity limiting post amplifier designed for fiber-optic receivers. It connects to typical transimpedance amplifiers (TIAs) and quantizes linear signals to output CML level waveforms. The device operates from a single +3.3V power supply and is rated for a temperature range of ,Äì40¬8C to +85¬8C. It supports data rates from 155Mbps to 3.2Gbps, with a minimum input sensitivity of 4mV_PP. Key features include a high-gain loss-of-signal (LOS) detection with a programmable sensitivity level, a TTL enable input, and low-noise CML data outputs. The LOS output is designed to be chatter-free, with internal hysteresis to enhance stability. The SY88343HLMG is packaged in a compact 16-pin QFN format, making it suitable for applications in various optical transceivers and data communication systems, including FTTX, Gigabit Ethernet, and SONET/SDH.
