The RC22504A is a small, low-power timing component designed to be placed immediately adjacent to a PHY, switch, ASIC or FPGA that requires several reference clocks with jitter performance less than 100fs (max). The RC22504A can act as a frequency synthesizer to locally generate the reference clock or as a DCO for frequency margining or OTN clock applications.
