ANALOG DEVICES AD8561ARZ

AD8561 is a single supply comparator with separate input and output sections. Fast 7ns propagation delay makes the device a good choice for timing circuits and line receivers. Propagation delays for rising and falling signals are closely matched and track over temperature. This matched delay makes the device a good choice for clock recovery, since the duty cycle of the output will match the duty cycle of the input. It is widely used in application such as high speed timing, clock recovery and clock distribution, line receivers, digital communications, phase detectors, high speed sampling, read channel detection, PCMCIA Cards, upgrade for LT1016 designs etc.
