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 [email protected]. Full transition to SiTime is expected by late 2026.

The 844008I-15 is an 8 output LVDS synthesizer optimized to generate PCI Express reference clock frequencies. Using a 25MHz parallel resonant crystal, the following frequencies can be generated based on F_SEL pin: 100MHz or 125MHz. The 844008I-15 uses our 3rd generation low phase noise VCO technology and can achieve <1ps typical rms phase jitter, easily meeting PCI Express jitter requirements. The 844008I-15 is packaged in a 32-pin LQFP package.
