MicroClock Programmable Clock 5L1503 Datasheet Generator Description Features Proactive Power Saving (PPS) features save power during the The 5L1503 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 an external Multiple output clock amplitude (1V, 1.1V, 1.2V and 1.8V) to fundamental crystal or clock input. The device allows up to 3 support low swing clock requirement unique frequency outputs. The 5L1503 has built-in unique features such as Proactive Power Saving (PPS) and an extreme Dedicated 32kHz output with 6 clock amplitude options low power DCO to support system date/time keeping clock at (5L1503L) 32.768kHz. Dynamic Frequency Control (DFC) supports Configurable through OTP programming dynamically changing between four different PLL frequencies via Spread spectrum clock support (5L1503S) external requests with controlled frequency changes, reducing 1.8V operating supply voltage frequency overshoot and undershoot (ORT). The 5L1503S device can also support a spread clock output for EMI reduction. For a 2 2 mm 10-VFQFPN package description of terms and their functions, see Glossary of Features. Output Features An internal OTP memory allows the user to store up to four independent configurations that can be loaded on power-up 3 LVCMOS outputs, 1MHz100MHz or 32.768kHz without programming. Low-power 32.768kHz clock supported The 5L1503 supports three LVCMOS type outputs with VDDO1.8V, as well as various amplitude clocks. A low-power Key Specifications 32.768kHz clock is supported with only less than 1 A current consumption for system RTC reference clock needs. Output cycle-cycle jitter: 50ps (typ) Low power-on fully active mode: 2mA (typ) Low-power 32.768kHz < 1.0 A (5L1503L) 5L1503 Base VCO Range Description Number (MHz) 5L1503 Standard, External Crystal 50 130 5L1503L Ultra Low-power, External Crystal 50 130 5L1503S Spread Clock, External Crystal 500 1100 Typical Applications SmartDevice Handheld Wearable applications Portable Consumer applications 2019 Integrated Device Technology, Inc 1 December 13, 20195L1503 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 5L1503 7 5L1503L . 7 5L1503S . 7 OE Pin Function . 7 Spread Spectrum . 9 Spread Spectrum 9 Digital Spread Spectrum . 9 Reference Input and Selection 9 Crystal Input (X1/X2) . 9 Absolute Maximum Ratings 11 Thermal Characteristics . 11 Recommended Operating Conditions 11 Crystal Characteristics 12 DC Electrical Characteristics . 12 AC Electrical Characteristics . 13 I2C Bus DC Characteristics 15 Spread Spectrum Generation Specifications . 16 General I2C Interface Information . 17 How to Write . 17 How to Read . 17 Glossary of Features . 27 Package Outline Drawings . 28 Ordering Information . 28 Marking Diagrams . 28 Revision History . 29 2019 Integrated Device Technology, Inc 2 December 13, 2019
