- I²C Interface
- Supported by the Timing Commander™ software tool
Description
The 5L2503 MicroClock™ is a programmable clock generator intended for low-power, consumer, wearable, and smart devices. The 5L2503 device is a 3 PLL& architecture design. Each PLL is individually programmable, allowing for up to 3 unique frequency outputs. The 5L2503 has built-in unique features such as Proactive Power Saving (PPS) to deliver better system-level power management.
An internal OTP memory allows the user to store the configuration in the device without programming after power-up and then the device can be reprogrammed again through the I²C interface. The 5L2503 has programmable VCO and PLL source selection allowing the user to do power-performance optimization based on the application requirements. A low-power 32.768kHz clock is supported with only less than 2μA current consumption for system RTC reference clock needs.
