MicroClock Programmable Clock 5X2503 Generator Datasheet Description Features The 5X2503 MicroClock is a programmable clock generator and is Configurable OE1 pin function as OE, PPS or DFC control function intended for low-power, consumer, wearable and smart devices. PPS: Proactive Power Saving features save power during the end The 5X2503 device is a 3 PLL architecture design. Each PLL is device power-down mode individually programmable, allowing for up to 3 unique frequency DFC: Dynamic Frequency Control feature allows programming up outputs. The 5X2503 has built-in unique features such as Proactive to 4 difference frequencies that switch dynamically Power Saving (PPS) to deliver better system-level power management. Integrated 26MHz crystal no external input source requirement Spread spectrum clock support to lower system EMI An internal OTP memory allows the user to store the configuration in 2 the device without programming after power up. It can then be I C Interface 2 reprogrammed again through the I C interface. Output Features The device has programmable VCO and PLL source selection allowing the user to do power-performance optimization based on 3 LVCMOS outputs, 1MHz125MHz the application requirements. A low-power 32.768kHz clock is Low-power 32.768kHz clock supported supported with only less than 2 A current consumption for system Wireless clock crystal integration and fan-out directly RTC reference clock needs.
