Features
iT4031F
100-ps Wideband Phase Delay
The iT4031F is a RoHS-6-compliant, ultra-wideband phase delay fabricated using 1-um HBT
GaAs technology and is based on ECL topology to guarantee high-speed operation. The high
output voltage, excellent rise and fall time, and the high eye diagram quality at data rates to 12.5
Gb/s makes the iT4031F is suitable for timing adjustment in data and clock distribution at very
high speed. Complex digital applications benefit from the iT4031F, including clock data recovery,
edge detectors, NRZ-to-RZ converters, MUX/DEMUX, and data restoration.
The device features a single delay element that provides up to 100-ps delay. Delay control can
be either differential (using both VCp and VCm) or single-ended (VCm is the active control pad
while VCp is shorted to VCref). The control voltage range for the delay input is from -2.2 V to -3.0
V whether the control is single-ended or differential. The device can delay NRZ streams with data
rates to 12.5 Gb/s or a clock signal up to 10.7 GHz. Both inputs and outputs are DC-coupled.
The iT4031F uses SCFL I/O levels and is designed so to allow for either single ended or
differential data input.
