Microchip | SY88903VKG

The SY88903VKG is a 1 GHZ 5 V / 3.3 V High-Speed Limiting post amplifier with its high gain and wide bandwidth is ideal for use as a post amplifier in fiber optic receivers with data rates up to 1.25 Gbps. Signals as small as 5 mVpp can be amplified to drive devices with PECL inputs

The SY88903V generates a chatter-free, Loss- -of-Signal (LOS), open-collector TTL output. The SY88903V is an integrated limiting amplifier intended for high-frequency fiber optic applications. The circuit connects to typical transimpedance amplifiers found within a fiber optics link.
