Datasheet IDT 5L1503

MicroClock Programmable Clock
Generator 5L1503 Datasheet Description Features The 5L1503 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 an external
fundamental crystal or clock input. The device allows up to 3
unique frequency outputs. The 5L1503 has built-in unique
features such as Proactive Power Saving (PPS) and an extreme
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. For a
description of terms and their functions, see Glossary of Features. ▪ Multiple 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
