Device Overview

Summary

The SY88793V 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 SY88793V quantizes these signals and outputs PECL level waveforms. The SY88793V operates from a single +3.3V or +5V power supply, over temperatures ranging from –40°C to +85°C. With its wide bandwidth and high gain, signals with data rates up to 622Mbps and as small as 5mVpp can be amplified to drive devices with PECL inputs. The SY88793V generates a TTL SD output. A programmable signal-detect level set pin (SDLVL) sets the sensitivity of the input amplitude detection. SD asserts high if the input amplitude rises above the threshold set by SDLVL and deasserts low otherwise. EN deasserts the true output signal without removing the input signal. Typically 6dB SD hysteresis is provided to prevent chattering.
