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 fr...
