SY88903AL
3.3V, Burst Mode 1.25Gbps PECL HighSensitivity Limiting Post Amplifier with TTL Loss-of-Signal
General Description
Features
The SY88903AL, burst mode, high-sensitivity limiting • Single 3.3V power supply post amplifier is designed for use in fiber-optic receivers, • Fast LOS release/assert (<500ns) time for PON specially optimized for passive optical networks (PONs). applications The device connects to typical transimpedance • 622Mbps to 1.25Gbps operation amplifiers (TIAs). The linear signal output from TIAs can • Low-noise PECL data outputs contain significant amounts of noise and may vary in • High gain LOS amplitude over time. The SY88903AL quantizes these signals and outputs PECL level waveforms.
