Description

The 5X2503 MicroClock is a programmable clock generator and is

intended for low-power, consumer, wearable and smart devices.

The 5X2503 device is a 3 PLL architecture design. Each PLL is

individually programmable, allowing for up to 3 unique frequency

outputs. The 5X2503 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. It can then be

reprogrammed again through the I2

C interface.

The device 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.

Features
