5L2503
MicroClock Programmable Clock
Generator
5L2503
Datasheet
Description
The 5L2503 MicroClock programmable clock generator is
intended for low-power, consumer, wearable and smart devices.
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.
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.
Typical Applications
SmartDevice
Handheld
Wearable applications
Consumer application crystal replacements
Features
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
Output Features
3 LVCMOS outputs: 1MHz–125MHz
Low Power 32.768kHz clock supported
Wireless clock crystal integration and fan out directly
