SY88343BL - Micrel Semiconductor

SY88343BL CML Limiting Post Amplifier

Features The SY88343BL 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) • Low-noise CML data outputs that are AC-coupled. The linear signal output from TIAs • High gain LOS can contain significant amounts of no.

Features

The SY88343BL 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)
• Low-noise CML data outputs that are AC-coupled. The linear signal output from TIAs
• High gain LOS can contain significant amounts of noise and may vary
• Chatter-free Open-Collector TTL Loss-of-Signal in amplitude over time. The SY88343BL quantizes these (LOS) output with internal 4.75kΩ pull-up resistor signals and outputs CML-level waveforms.
• TTL /EN input The SY88343BL operates.
