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 В±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), …
