Description
The 5X1503 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 one embedded crystal. The device is OTP programmable, allowing for up to three unique frequency outputs. The 5X1503 has built-in unique features such as Proactive Power Saving (PPS) and a 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 5X1503S device can also support a spread clock for EMI reduction.
An internal OTP memory allows the user to store up to four independent configurations that can be loaded on power-up without programming. It can then be reprogrammed again through the I²C interface.
The 5X1503 supports three LVCMOS type outputs. Two outputs have programmable amplitude. A low-power 32.768kHz clock is supported with only less than 1.5μA current consumption for system RTC reference clock needs.
