MicroClock Programmable Clock 5X1503 Generator Datasheet Description Features
The 5X1503 is a series of small form factor programmable clock ▪ Proactive Power Saving (PPS) features save power during the generators intended for low-power, consumer, battery powered end device power-down mode applications, wearable and smart devices. ▪ Dynamic Frequency Control (DFC) feature allows programming The device is a 1 PLL + DCO architecture design with one up to 4 difference frequencies that switch dynamically embedded crystal. The device is OTP programmable, al owing for ▪ Programmable output clock amplitude (1V, 1.1V, 1.2V and up to 3 unique frequency outputs. The 5X1503 has built-in unique 1.8V) to support low swing clock requirement 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 dynamical y changing ▪ Integrated crystal; no external input source requirement between four different PLL frequencies via external requests with ▪ control ed frequency changes, reducing frequency overshoot and Configurable through I2C or OTP programming undershoot (ORT). The 5X1503S device can also support a ▪ Spread spectrum clock support (5X1503S) 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

without programming. It can then be reprogrammed again through the I2C interface. ▪ 3 LVCMOS outputs, 1MHz–100MHz or 32.768kHz ▪ 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 supported with only less than 1.5μA current consumption for
