SY88289BL
3.3V, 3.2Gbps CML Limiting Post Amplifier with High-Gain TTL Loss-of-Signal
General Description
Features
The SY88289BL low-power limiting, post amplifier is • Single 3.3V power supply designed for use in fiber-optic receivers. The device • DC to 3.2Gbps operation connects to typical transimpedance amplifiers (TIAs). • Low-noise CML data outputs 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 signal detect (LOS) over time. The SY88289BL quantizes these signals and output with internal 4.75kΩ pull-up resistor outputs CML level waveforms. • TTL /EN input The SY88289BL operates from a single +3.3V power supply, over temperatures ranging from –40oC to +85oC.
