SY88289CL
3.3V, 3.2Gbps CML Limiting Post Amplifier with High-Gain TTL Loss-of-Signal
General Description
Features
The SY88289CL low-power, high-sensitivity, limiting • Single 3.3V power supply post amplifier is designed for use in fiber-optic receivers. • 125Mbps to 3.2Gbps operation The device connects to typical transimpedance • Low-noise CML data outputs amplifiers (TIAs). The linear signal output from TIAs can • High-gain LOS contain significant amounts of noise and may vary in • Chatter-free open-collector TTL Loss-of-Signal (LOS) amplitude over time. The SY88289CL quantizes these output with an internal 4.75kΩ pull-up resistor signals and outputs CML-level waveforms. • TTL /EN input The SY88289CL operates from a single +3.
