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.

Features

  • Packaged in 20-pin SSOP (QSOP) – Pb-free, RoHS compliant
  • Operating voltage of 3.3 V
  • Highly accurate frequency generation
  • M/N Multiplier PLL: M = 1..2048, N = 1..1024
  • Serially programmable: user determines the output frequency via a 3-wire interface
  • Eliminates need for custom quartz oscillators
  • Input crystal frequency of 5 - 27 MHz

Description

The 308 is a versatile serially programmable, quad PLL clock source. The 308 can generate any frequency from 250 kHz to 200 MHz, and up to 6 different output frequencies simultaneously. The outputs can be reprogrammed on the fly, and will lock to a new frequency in 10 ms or less. Smooth transitions (in which the clock duty cycle remains roughly 50%) are guaranteed if the output divider is not changed. The device includes a PDTS pin which tri-states the output clocks and powers down the entire chip. The 308 default for non-programmed start-up are buffered reference clock outputs on all clock output pins.

  3. R_SPI_WriteRead is non blocking

    Hi, I need to read SPI registers from task as well as ISR. So setting flag is not an option and I can not take semaphores from ISR. Is there a way to block the R_SPI_WriteRead function. Thanks This thread was automatically locked due to age.
