SY88147DL
3.3V, 1.25Gbps PECL Limiting Post Amplifier w/High Gain TTL Loss-of-Signal
General Description
Features
The SY88147DL is a high-sensitivity limiting post • Single 3.3V power supply amplifier designed for use in fiber-optic receivers. These • DC to 1.25Gbps operation devices connect to typical transimpedance amplifiers • Low-noise PECL data outputs (TIAs). The linear signal output from TIAs can contain • High-gain LOS significant amounts of noise and may vary in amplitude • Chatter-free Open-Collector TTL Loss of Signal over time. The SY88147DL quantizes these signals and (LOS) output with internal 4.75kΩ pull-up resistor outputs PECL level waveforms. • TTL /EN input The SY88147DL operates from a single +3.3V power supply, over temperatures ranging from –40oC to +85oC.
