Renesas’ Timing product portfolio has been acquired by SiTime.
Datasheets, documentation, and sample orders remain available on Renesas.com through late 2026. For new designs, purchasing, support, and product inquiries, visit SiTime.com or send an email to SalesClocks@sitime.com. Full transition to SiTime is expected by late 2026.

The RC32504A 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 a jitter performance of less than 100fs. 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.
