PLL-based clock generation from a 32.768 kHz crystal
The 5L2503-000NVGI is a PLL-based clock generator from Renesas' MicroCLock™ series. It takes a 32.768 kHz crystal input and outputs LVCMOS clock signals — the PLL multiplies the crystal reference to generate the output frequencies, making it suitable for real-time clock (RTC) and low-frequency timing applications. With a 1:3 input-to-output ratio and three clock outputs, this device can distribute a clean, jitter-filtered clock to multiple loads from a single crystal source. The PLL locks to the crystal and cleans up the phase noise, which matters when the downstream logic (MCU, FPGA, or sensor interface) needs a stable reference without a separate crystal per load.
Supply voltage and temperature range — industrial fit
The supply voltage range of 1.71V to 1.89V aligns with 1.8V logic families. The 12-DFN (2.5x2.5) package is compact but requires careful soldering; the exposed pad must be connected to ground for thermal dissipation and to provide a low-impedance return path for the PLL's internal charge pump.
The part is supplied in strip packaging, which typically means it is available in small quantities for prototyping or low-volume production.
