1 / 29 page  1 ©2017 Integrated Device Technology, Inc. October 24, 2017 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 Key Specifications ▪ 2μA operation for RTC clock 32.768kHz output ▪ 2.5 × 2.5 mm 12-DFN small form factor package Block Diagram Overshoot Reduction (ORT) OSC PLL2 OUT3 OUT2 OUT1 PLL3 OE1 SDA_DFC0/OE2 SEL_DFC/ SCL_DFC1/OE3 OTP memory (1 configuration ) Proactive Power Saving Logic (PPS) I2C Engine Dynamic Frequency Control Logic (DFC) POR Power Monitor VDD1_8 32.768K DCO Calibration VSS VDDO PLL1 VSS Mux & Divider XOUT CLKIN/ XIN 5L2503 Datasheet MicroClock Programmable Clock Generator |
