Description

The SY88953L high-speed 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 SY88953L quantizes these signals and outputs CML level waveforms.

The SY88953L operates from a single +3.3V power supply, over temperatures ranging from 40°C to +85°C. With its wide bandwidth and high gain, signals with data rates up to 10.7Gbps and as small as 5mVp-p can be amplified to drive devices with CML inputs.

The SY88953L outputs TTL signal-detect (SD and /SD) signals. 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 is the complementary output of SD. /SD can be fedback 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 6dB SD hysteresis is provided to prevent chattering.

The SY88953L also includes an input threshold adjustment to correct pulsewidth distortion.
