DIFFERENTIAL 2-CHANNEL
PRECISION CML DELAY LINE
1
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.
ended 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).
DESCRIPTION
The SY55856U is a 2.5GHz, two-channel, fully differential
The SY55856U inputs are designed to accept single-
