2Gbps CML Low-Power Limiting Post Amplifier w/ High-Gain TTL Signal Detect
General Description
Features
• Single 3.
3V power supply The SY88345BL high-sensitivity limiting post amplifier is designed for use in fiber-optic receivers.
The device • 155Mbps to 3.
2Gbps operation connects to typical transimpedance
amplifiers (TIAs).
• Low-noise CML data outputs The linear signal output from TIAs can contain • Chatter-free Open-Collector TTL signal detect (SD) significant amounts of noise and may vary in amplitude output with internal 4.
75kΩ pull-up resistor over time.
The SY88345BL quantizes these signals and • TTL EN input outputs CML-level waveforms.
• Internal 50Ω input term...
