Renesas Electronics Corporation

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.

Description

The ICS601-01 is a low-cost, low phase noise, high-performance clock synthesizer for applications which require low phase noise and low jitter. It is Renesas’ lowest phase noise multiplier, and also the lowest CMOS part in the industry. Using Renesas’ patented analog and digital Phase-Locked Loop (PLL)  techniques, the chip accepts a 10 - 27 MHz crystal or clock input, and produces output clocks up to 156 MHz at 3.3 V. This product is intended for clock generation. It has low output jitter (variation in the output period), but input to output skew and jitter are not defined nor guaranteed. For applications which require defined input to output timing, use the ICS670-01.
