SY88149CL Datasheet | Micrel Semiconductor

3.3V, 1.25Gbps PECL Limiting Post Amplifier w/High Gain TTL Signal Detect General Description The SY88149CL is a high-sensitivity limiting post amplifier designed for use in fiber-optic receivers. These devices connect 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 SY88149CL quantizes these signals and outputs PECL level waveforms. The SY88149CL operates from a single +3.3V power supply, over temperatures ranging from - 40oC to +85oC. With its wide bandwidth and high gain, signals with data rates up to 1.25Gbps, and as small as 5mVpp, can be amplified to drive...
