MicroClock Programmable Clock
Generator 5X2503 Datasheet Description Features The 5X2503 MicroClock is a programmable clock generator and is
intended for low-power, consumer, wearable and smart devices. ▪ Configurable OE1 pin function as OE, PPS or DFC control
function
▪ PPS: Proactive Power Saving features save power during the end
device power-down mode
▪ DFC: Dynamic Frequency Control feature allows programming up
to 4 difference frequencies that switch dynamically
▪ Integrated 26MHz crystal; no external input source requirement
▪ Spread spectrum clock support to lower system EMI
▪ I2C Interface 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 I2C interface. Output Features 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. ▪ 3 LVCMOS outputs, 1MHz–125MHz
▪ Low-power 32.768kHz clock supported …
