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 554-01A is a low skew clock buffer with a single complimentary PECL input to four PECL outputs. Part of Renesas' Clock Blocks™ family, this is our lowest skew PECL clock buffer. The 554-01A is footprint compatible with the 554-01, but requires fewer passive components for termination thus providing a cost-saving alternative. For parts which do not require PECL inputs or outputs, see the 553 for a 1 to 4 low skew buffer, or the 552-02 for a 1 to 8 low skew buffer. For more than 8 outputs see the MK74CBxxx Buffalo™ series of clock drivers. Renesas makes many non-PLL and PLL based low skew output devices as well as Zero Delay Buffers to synchronize clocks.
