3.3V, Burst Mode 1.25Gbps PECL High-Sensitivity Limiting Post Amplifier with TTL Loss-of-Signal
General Description
The SY88903AL, burst mode, high-sensitivity limiting post amplifier is designed for use in fiber-optic receivers, specially optimized for passive optical networks PONs. The device connects to typical transimpedance amplifiers TIAs. The linear signal output from TIAs can contain significant amounts of noise and may vary in amplitude over time. The SY88903AL quantizes these signals and outputs PECL level waveforms.
Features
• Single 3.3V power supply
• Fast LOS release/assert <500ns time for PON applications
• 622Mbps to 1.25Gbps operation
• Low-noise PECL data outputs
• High gain LOS
• Chatter-free Open-Collector TTL signal detect LOS output with internal 4.75kΩpull-up resistor
• TTL /EN input
• Programmable LOS level set LOSLVL
• Available in a tiny 10-pin MSOP package
Applications
•GPON/GEPON/EPON
• Gigabit Ethernet, 1062Mbps Fibre Channel
•OC-12/24 SONET/SDH
• Low-gain TIA interface
• High-gain line driver and line receiver
