Features
iT4033D
100-ps Dual Independent
Wideband Phase Delay
(Advanced Information)
The iT4033D is a dual-independent 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 iT4033D suitable for timing adjustment in data and clock distribution at very high speed.
Complex digital applications benefit from the iT4033D, including clock data recovery, edge
detectors, NRZ-to-RZ converters, MUX/DEMUX, and data restoration. The device features a dual
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. At the input side, internal 50-ohm resistors
avoid the need for external impedance matching terminations. The iT4033D uses SCFL I/O levels
and is designed so to allow for either single ended or differential data input.
