SY88343BL
3.3V, 3.2Gbps CML Limiting Post Amplifier with High Gain TTL Loss-of-Signal
General Description
Features
The SY88343BL 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 that are AC-coupled. The linear signal output from TIAs • High gain LOS can contain significant amounts of noise and may vary • Chatter-free Open-Collector TTL Loss-of-Signal in amplitude over time. The SY88343BL quantizes these (LOS) output with internal 4.75kΩ pull-up resistor signals and outputs CML-level waveforms. • TTL /EN input The SY88343BL operates from a single +3.3V power supply, over temperatures ranging from –40oC to +85oC.
