Renesas Electronics RC22504A and RC32504A FemtoClock® 2 Synthesizers are designed to be placed adjacent to a PHY, switch, ASIC, or FPGA that requires several reference clocks with less than 100fs (max) jitter performance. The RC22504A acts as a frequency synthesizer to locally generate the reference clock or as a DCO for frequency margining or OTN clock applications. The RC32504A can act as a frequency synthesizer to locally generate the reference clock, a jitter attenuator to perform local clean-up and/or frequency translation of a centrally-supplied reference, a Synchronous Ethernet equipment clock to perform passband filtering and clean-up of network-supplied references, or as a DCO for frequency margining or OTN clock applications. These devices are members of Renesas' high-performance FemtoClock2 family.
