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 552A-01 produces 8 low-skew copies of the multiple input clock or fundamental, parallel-mode crystal. Unlike other clock drivers, these parts do not require a separate oscillator for the input. Using IDT's patented Phase-Locked Loop (PLL) to multiply the input frequency, it is ideal for generating and distributing multiple high-frequency clocks. This is a single chip used for 3 different applications: 1) 552A-01 (A mode) — an Oscillator mutiplier 2) 552A-01 (B mode) — a Dual 1:4 buffer 3) 552A-01 (C mode) — a 1:8 Oscillator buffer
