Description

The 5L35021 is a member of the VersaClock 3S programmable

clock generator family with 1.8V operation voltage, and is

designed for industrial, consumer, and PCI Express applications.

The device features a 3 PLL architecture design; each PLL is

individually programmable and allowing up to 6 unique frequency

outputs.

The 5L35021 has built-in features such as Proactive Power

Saving (PPS), Performance-Power Balancing (PPB), Overshoot

Reduction Technology (ORT) and extreme low power DCO. An

internal OTP memory allows the user to store the configuration in

the device without programming after power up, then program the

5L35021 again through the I2

C interface.

The device has programmable VCO and PLL source selection,

allowing power-performance optimization based on the application

requirements.

Typical Applications

? Embedded computing devices

? Consumer application crystal replacements

? SmartDevice, Handheld, and Consumer applications

Features

? Configurable OE pin function as OE, PD#, PPS or DFC control function

? Configurable PLL bandwidth; minimizes jitter peaking

? PPS: Proactive Power Saving features save power during the end device power down mode

? PPB: Performance Power Balancing feature allows minimum power consumption based on required performance

? DFC: Dynamic Frequency Control feature allows user to dynamically switch between and up to 4 different frequencies smoothly

? Spread spectrum clock to lower system EMI

? I2C interface

? Suspend Mode, featuring RTC clock only when system goes into low-power operation modes
