5X2503

MicroClock Programmable Clock Generator 5X2503 Datasheet 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 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 replacement Block Diagram Features ▪ 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 Output Features ▪ 3 LVCMOS outputs, 1MHz–125MHz ▪ Low...
