SY88289CL

SY88289CL 3.3V, 3.2Gbps CML Limiting Post Amplifier with High-Gain TTL Loss-of-Signal General Description Features The SY88289CL low-power, high-sensitivity, limiting Single 3.3V power supply post amplifier is designed for use in fiber-optic receivers. 125Mbps to 3.2Gbps operation The device connects to typical transimpedance Low-noise CML data outputs amplifiers (TIAs). The linear signal output from TIAs can High-gain LOS contain significant amounts of noise and may vary in Chatter-free open-collector TTL Loss-of-Signal (LOS) amplitude over time. The SY88289CL quantizes these output with an internal 4.75kΩ pull-up resistor signals and outputs CML-level waveforms. TTL /EN input The SY88289CL operates from a single +3.3V power supply, over temperatures ranging from –40oC to +85oC. Programmable LOS level set (LOSLVL) With its wide bandwidth and high gain, signals with data Ideal for multi-rate applications rates up to 3.2Gbps and as small as 5mVPP can be Available in a tiny (3mm x 3mm) 16-pin MLF® amplified to drive devices with CML inputs or ACpackage coupled CML/PECL inputs. The SY88289CL generates a high-gain loss-of-signal Applications (LOS) open-collector TTL output. This function has a APON, BPON, EPON, GEPON and GPON high-gain input stage for increased LOS sensitivity. A Gigabit Ethernet programmable loss-of-signal level-set pin (LOSLVL) sets 1X and 2X Fibre Channel the sensitivity of the input amplitude detection. LOS www.DataSheet4U.com SON...
