Features

The SY88347DL low-power limiting post amplifier is
• Single 3.3V power supply designed for use in fiber-optic receivers. The device
• 155Mbps to 3.2Gbps operation connects to typical transimpedance amplifiers (TIAs).
• Low-noise PECL data outputs The linear signal output, from TIAs, can contain
• High-gain LOS output significant amounts of noise and may vary in amplitude
• Chatter-free Open-Collector TTL Loss-of-Signal over time. The SY88347DL quantizes these signals and (LOS) output outputs PECL-level waveforms.
• TTL /EN input The SY88347DL operates from a single +3.3V power supply, over te.
