The NB4N507A PLL clock IC generates a clock signal ranging from 50 to 200 MHz via an inexpensive reference crystal. The device offers an rms period jitter of less than 10 ps and an accuracy of 100 ppm ...
Optical networking equipment using the OC-3 (155.52 MHz) Sonet/SDH standard has another option to exploit in the ZL30410 digital phase-locked loop (PLL). The chip generates and synchronizes clock ...
