SY88313BL
3.3V, 3.2Gbps CML Low-Power Limiting Post Amplifier with TTL Loss-of-Signal
General Description
Features
The SY88313BL 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). The linear signal output from TIAs can contain • Low-noise CML data outputs significant amounts of noise and may vary in amplitude • Chatter-free Open-Collector TTL loss-of-signal over time. The SY88313BL quantizes these signals and (LOS) output with internal 4.75kΩ pull-up outputs CML-level waveforms. resistor The SY88313BL operates from a single +3.3V ±10% • TTL /EN input supply, over temperatures ranging from –40°C to +85°C.
