Description

The SY88983V 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 SY88983V quantizes these signals and outputs typically 800mVp-p voltage-limited waveforms.

The SY88983V 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 3.2Gbps and as small as 5mVp-p can be amplified to drive devices with CML inputs or AC-coupled PECL inputs.

The SY88983V generates a signal detect (SD) open-collector TTL output with internal 5k Ohm pull-up resistor. 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. SD can be fed back to the enable (EN) input to maintain output stability under a loss of signal condition. EN deasserts the true output signal without removing the input signal. Typically 4.6dB SD hysteresis is provided to prevent chattering.
