SY88289AL
3.3V, 3.2Gbps CML Low-Power Limiting Post Amplifier with TTL Loss-of-Signal
General Description
Features
The SY88289AL low-power limiting post amplifier is • Single 3.3V power supply designed for use in fiber-optic receivers. The device • 125Mbps to 3.2Gbps operation connects to typical transimpedance amplifiers (TIAs). • Low-noise CML data outputs The linear signal output from TIAs can contain • Chatter-free open-collector TTL Loss-of-signal (LOS) significant amounts of noise and may vary in amplitude output with internal 4.75kΩ pull-up resistor over time. The SY88289AL quantizes these signals and • TTL /EN input outputs CML-level waveforms. • Internal 50Ω input termination The SY88289AL operates from a single +3.3V power supply, over temperatures ranging from –40oC to +85oC.
