SY88289BL CML Limiting Post Amplifier

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.

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.
