MicroClock Programmable Clock
Generator 5X1503 Datasheet Description Features The 5X1503 is a series of small form factor programmable clock
generators intended for low-power, consumer, battery powered
applications, wearable and smart devices. ▪ Proactive Power Saving (PPS) features save power during the
end device power-down mode ▪ 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 one
embedded crystal. The device is OTP programmable, allowing for
up to 3 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. For a description of terms and
their functions, see Glossary of Features. ▪ Programmable output clock amplitude (1V, 1.1V, 1.2V and
1.8V) to support low swing clock requirement ▪ Dedicated 32kHz output with 6 clock amplitude options
