Description

The SY88933AL high-sensitivity 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 SY88933AL quantizes these signals and outputs PECL level waveforms.

The SY88933AL operates from a single +3.3V power supply, over temperatures ranging from 40oC to +85oC. With its wide bandwidth and high gain, signal with data rates up to 1.25Gbps and as small as 5mVPP can be amplified to drive devices with PECL inputs.

The SY88933AL generates a high gain signal-detect (SD) open-collector TTL output. The SD function has a high gain input stage for increased sensitivity. 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 de-asserts low otherwise. The enable input (EN) de-asserts the true output signal without removing the input signal. The SD output can be fed back to the EN input to maintain output stability under a loss-of-signal condition. Typically, 3.4dB SD hysteresis is provided to prevent chattering.
