The DM4031 is an 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 DM4031 suitable for timing adjustment in data and clock distribution at very high speed. Complex digital applications benefit from the DM4031, 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 DCcoupled. At the input side, internal 50-ohm resistors avoid the need for external impedance matching terminations. The DM4031 uses SCFL I/O levels and is designed so to allow for either single ended or differential data input.
