描述
The 5L1503 is a series of small form factor programmable clock generators intended for low-power, consumer, battery-powered applications, wearables, and smart devices.
The device is a 1 PLL + DCO architecture design with an external fundamental crystal or clock input. It allows up to three unique frequency outputs. The 5L1503 has built-in unique features such as Proactive Power Saving (PPS) and an extremely low power DCO to support system date/time keeping clock at 32.768kHz. Dynamic Frequency Control (DFC) supports dynamically changing between four different PLL frequencies via external requests with controlled frequency changes, reducing frequency overshoot and undershoot (ORT). The 5L1503S device can also support a spread clock output for EMI reduction.
An internal one-time programmable (OTP) memory allows the user to store up to four independent configurations that can be loaded on power-up without programming. The 5L1503 supports three LVCMOS type outputs with VDDO 1.8V, as well as various amplitude clocks. A low-power 32.768kHz clock is supported with only less than 1μA current consumption for system RTC reference clock needs.

Description
IDT's innovative support tool, Timing Commander™, expedites development cycles by empowering customers to program sophisticated timing devices with an intuitive and flexible Graphical User Interface. IDT's Timing Commander is a Windows™-based platform designed to serve user-friendly configuration interfaces, known as personalities, for various IDT products and product families. With a few simple clicks, the user is presented with a comprehensive, interactive block diagram offering the ability to modify desired input values, output values, and other configuration settings. The software automatically makes calculations, reports status monitors, and prepares register settings without the need to reference a datasheet. The tool also automatically loads the configuration settings over USB to an IDT evaluation board for immediate application in the circuit. Once the device has been configured and tuned for optimal system performance, the configuration file can be saved for factory-level programming before shipment.

Narrator: In a data driven world, timing is everything. That's why more and more system design engineers are using products from the world leader in silicon timing, IDT. IDT has earned its reputation for excellence by providing a wide range of leading technologies for wireless and wired communications infrastructure, high performance computing, and advanced power management.
And with a product portfolio 10 times greater than the competition, IDT is uniquely qualified to be your one-stop-shop for timing solutions. IDT's innovative Windows-based software platform, Timing Commander, makes it easy to configure, program, and monitor all your sophisticated timing devices.
Steven: What's great about IDT's Timing Commander is that it helps you avoid tedious manageable configurations so you can focus on other areas of your design.
Narrator: IDT's Timing Commander serves up intuitive configuration interfaces or personalities for all of IDT's programmable timing products. With a few simple clicks, you can generate a comprehensive, interactive block diagram and modified desired input values, output values, and other configuration settings. The software also writes your settings over USB to an IDT evaluation board for immediate application in the circuit. It really is as easy as one, two, three.
Steven: The Timing Commander software automatically makes calculations, monitors status, and prepares register settings so you don't have to reference a data sheet. Built-in documentation is readily available. Just hover over a setting, and real time validation ensures that the configuration complies with data sheet specifications. Whether you're a first time user or an experienced engineer, Timing Commander offers you the right amount of control.
Narrator: To help you program complex devices more intuitively, Timing Commander's advanced features include the ability to create phase noise estimates, generate the schematic symbol and termination circuit and determine the optimal balance between performance and power consumption.
Steven: Once your devices are configured and tuned for optimal system performance, you can save the configuration files for factory-level programming prior to shipment.
Narrator: Timing Commander is just one example of the innovative timing solutions IDT delivers.
Peter: From simple fanout buffers and multiplexers to fully featured products like universal frequency translators, network synchronization devices, and VersaClock families, IDT has a wide range of products optimized for specific applications. You can also count on IDT for the lowest jitter and lowest power features to help you build the world class products your customers demand.
Narrator: It's time to put IDT timing solutions to work for your business, and with the power of Timing Commander software, it's easier than ever. To learn more, visit IDT online or give us a call today.
