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.

DEV5L2503 SDA signal voltage change to 1.8V
... on the USB motherboard that allows the I2C pullup voltage to be set to 1.8V? The Timing Commander [V1.17] software shows a warning message about not finding the 5L2503 at it's known I2C addresses. The VDDOUT1 and VDDOUT2 voltages measure 1.87 VDC at TP7 and TP8.
