309RLF

The Renesas 309RLF is a clock/frequency synthesizer integrated circuit designed for generating precise clock signals in digital systems. It includes a phase-locked loop (PLL) with bypass mode, allowing flexible frequency synthesis. The device accepts a clock or crystal input and provides a single-ended LVCMOS output at frequencies up to 200MHz. With a 1:9 fanout ratio, it can distribute a single input to multiple outputs, and output dividers are available for frequency scaling.

Operating from a 3V to 3.6V supply voltage, the 309RLF is built for commercial temperature environments with a range of 0°C to 70°C. The output is non-differential, suitable for standard CMOS logic interfaces. The part is housed in a 20-SSOP package (also designated as 20-QSOP) with a 0.154" body width, enabling surface mount assembly.

The 309RLF is listed as RoHS3 compliant, REACH unaffected, and has an MSL rating of 1 (unlimited floor life), though these compliance values are unverified. No datasheet is currently available; specifications are based on existing product database records. The part is commonly used in clock generation and frequency synthesis applications where a stable, programmable clock source is required.
