Device Overview

Summary

The SY55856U is a 2.5GHz, two-channel, fully differential CML (Current Mode Logic) delay line. The device is optimized to adjust the relative delay between two channels, such as clock and data, in 50ps increments. Both inputs may be adjusted in either direction in 7 increments of 50ps, for a total adjustment range of ±350ps. In addition, the clock input maybe inverted through the CINV control pin.The SY55856U inputs are designed to accept singleended or differential CML signals. The differential CML outputs are optimized for 50Ω loads (50Ω source terminated), thus only requires a single 100Ω resistor across the output pair. Output rise and fall time is an extremely fast 110ps(max) and the differential swing is 400mV. The maximum throughput of the SY55856U is guaranteed to exceed 2.5GHz (5Gbps).
