Overview
Description
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.
Features
- Proactive Power Saving (PPS) features save power during the end device power-down mode
- Dynamic Frequency Control (DFC) feature allows programming up to 2 different configurations that switch dynamically
- Programmable output clock amplitude(1.0V, 1.1V, 1.2V, and 1.8V) to support low output swing clock requirement
- Dedicated 32kHz output with 8 options clock amplitude (5L1503L)
- Spread spectrum compatible; tracks spreading input clock for low EMI (5L1503S)
- OTP programming
- Supported by Renesas' Timing Commander™ software tool
