SY88147DL Datasheet | Micrel Semiconductor

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...
