MicroClock Programmable Clock 5X1503 Datasheet Generator Description Features Proactive Power Saving (PPS) features save power during the The 5X1503 is a series of small form factor programmable clock end device power-down mode generators intended for low-power, consumer, battery powered applications, wearable and smart devices. Dynamic Frequency Control (DFC) feature allows programming up to 4 difference frequencies that switch dynamically The device is a 1 PLL + DCO architecture design with one Programmable output clock amplitude (1V, 1.1V, 1.2V and embedded crystal. The device is OTP programmable, allowing for 1.8V) to support low swing clock requirement up to 3 unique frequency outputs. The 5X1503 has built-in unique features such as Proactive Power Saving (PPS) and a low power Dedicated 32kHz output with 6 clock amplitude options DCO to support system date/time keeping clock at 32.768kHz. (5X1503L) Dynamic Frequency Control (DFC) supports dynamically changing Integrated crystal no external input source requirement between four different PLL frequencies via external requests with Configurable through I2C or OTP programming controlled frequency changes, reducing frequency overshoot and Spread spectrum clock support (5X1503S) undershoot (ORT). The 5X1503S device can also support a spread clock for EMI reduction. For a description of terms and 1.8V operating supply voltage their functions, see Glossary of Features. 2 2 mm 10-VFQFPN package An internal OTP memory allows the user to store up to four independent configurations that can be loaded on power-up Output Features without programming. It can then be reprogrammed again through 3 LVCMOS outputs, 1MHz100MHz or 32.768kHz 2 the I C interface. Low-power 32.768kHz clock supported The 5X1503 supports three LVCMOS type outputs. Two outputs have programmable amplitude. A low-power 32.768kHz clock is Key Specifications supported with only less than 1.5 A current consumption for system RTC reference clock needs. Output cycle-cycle jitter: 50ps (typ) Low power-on fully active mode: 2mA (typ) 5X1503 Base VCO Range Low-power 32.768kHz < 1.0 A (5X1503L) Description Number (MHz) 5X1503 Standard, Integrated Crystal 50 130 5X1503L Ultra Low-power, Integrated Crystal 50 130 5X1503S Spread Clock, Integrated Crystal 500 1100 Typical Applications SmartDevice Handheld Wearable applications Portable Consumer applications 2019 Integrated Device Technology, Inc 1 June 19, 20195X1503 Datasheet Contents Description 1 Typical Applications . 1 Features 1 Output Features 1 Key Specifications 1 Block Diagram . 3 Pin Assignments 3 Pin Descriptions 4 Device Feature and Function 4 DFC Dynamic Frequency Control 4 DFC Function Programming 5 PPS Proactive Power Saving Function 5 PPS Function Programming 6 Output Divider Selection . 6 Device Output Support 7 5X1503 7 5X1503L . 7 5X1503S . 7 Input Pin Function 7 Spread Spectrum . 9 Spread Spectrum 9 Digital Spread Spectrum . 9 Absolute Maximum Ratings 10 Thermal Characteristics . 10 Recommended Operating Conditions 10 Crystal Characteristics 11 DC Electrical Characteristics . 11 AC Electrical Characteristics . 12 I2C Bus DC Characteristics 14 Spread Spectrum Generation Specifications . 15 General I2C Interface Information . 16 How to Write . 16 How to Read . 16 Glossary of Features . 26 Package Outline Drawings . 27 Ordering Information . 27 Marking Diagrams . 27 Revision History . 28 2019 Integrated Device Technology, Inc 2 June 19, 2019
