MicroClock Programmable Clock
Generator 5L2503 Datasheet Description Features The 5L2503 MicroClock programmable clock generator is
intended for low-power, consumer, wearable and smart devices. ▪ Configurable OE1 pin function as OE, PPS or DFC control
function
▪ Proactive Power Saving (PPS) features save power during the
end device power down mode
▪ Dynamic Frequency Control (DFC) feature allows programming
up to 4 difference frequencies switch dynamically
▪ Spread spectrum clock support to lower system EMI
▪ I2C Interface The 5L2503 device is a 3 PLL architecture design. Each PLL is
individually programmable, allowing 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 can
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
▪ Wireless clock crystal integration and fan out directly Key Specifications Typical Applications …
