Device Overview

Summary

The SY88843V 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 SY88843V quantizes these signals and outputs typically 800mVPP voltage-limited waveforms. The SY88843V operates from a single +3.3V±10% or +5V±10% power supply, over an industrial temperature range of -40°C to +85°C. With its wide bandwidth and high gain, signals with data rates up to 3.2Gbps and as small as 10mVp-p can be amplified to drive devices with CML inputs or AC-coupled PECL inputs. The SY88843V incorporates a signal detect (SD), open-collector TTL output with internal 4.75kΩ pull-up resistor. A programmable, loss-of-signal 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 de-asserts low otherwise. SD can be fed back to the enable (EN) input to maintain output stability under a loss of signal condition. EN asserts the true output signal without removing the input signal. Typically 4.6dB SD hysteresis is provided to prevent chattering. Please see Micrel's website at www.micrel.com for a complete selection of optical module ICs. The following table summarizes the differences between devices in Micrel's latest family of Limiting Amplifiers.
