Micrel’s SY88353BL is a low-power, high-performance, 3.2 Gbps limiting amplifier optimized for Wavelength Division Multiplexing (WDM) systems and is also ideally suited for Gigabit Ethernet, 1X and 2X Fiber Channel, and OC-3/STM-1 through OC-48/STM-16 applications.

The SY88353BL limiting post amplifier provides a unique pin at which a variable dc signal can be applied to adjust output signal crossing from 20% to 80%. This feature eliminates input dc offsets in dc-coupled applications, minimizes jitter caused by duty cycle distortion and ultimately optimizes bit error rate (BER) performance.

The SY88353BL operates from a single 3.3 V power supply. Input signals with data rates from 155 Mbps up to 3.2 Gbps and as small as 10 mV pp, can be amplified to drive devices with CML or PECL inputs. The device offers fast loss-of-signal (LOS) release/assert time, low-noise CML data outputs, and a chatter-free Open-Collector TTL LOS feature.

This IC is available in a 3 mm x 3 mm MLF package. Volume pricing starts at $3.13 for 10,000-unit quantities.
