SY88933AL - PECL High-Sensitivity Limiting Post Amplifier

Datasheet Summary

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.

Features

  • Single 3.3V power supply.
  • DC-to-1.25Gbps operation.
  • Low-noise PECL data outputs.
  • High gain SD.
  • Chatter-free open-collector TTL signal detect (SD) output with internal 4.75kΩ pull-up resistor.
  • TTL EN input.
  • Programmable SD level set (SDLVL).
  • Available in a tiny 10-pin MSOP package.
  • Pin-compatible with SY88933V.

SY88933AL 3.3V, 1.25Gbps PECL High-Sensitivity Limiting Post Amplifier w/TTL Signal Detect General 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.
