The iT4036F is an ultra-wideband phase delay with an ECL topology to ensure high-speed operation that accepts either single-ended or differential data input. Its high output voltage, excellent rise and fall times, and high eye diagram quality at data rates up to 12.5 Gb/s make the iT4036F suitable for timing adjustment in data and clock distribution at very high speed. Complex digital applications benefit from the iT4036F, 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 120-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 -1.3 V to -1.9 V whether the control is single-ended or differential. The device can delay NRZ streams with data rates up to 12.5 Gb/s or a clock signal up to 12.5 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 iT4036F is housed in a 5x5-mm RoHS-6-compliant QFN package. |
