5L35023集成電路（IC）的時(shí)鐘發(fā)生器PLL頻率合成器規(guī)格書PDF中文資料

Description

The 5L35023 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 5L35023 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

5L35023 again through the I2

C interface.

The device has programmable VCO and PLL source selection,

allowing power-performance optimization based on the application

requirements.

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

Typical Applications

? Embedded computing devices

? Consumer application crystal oscillator replacements

? SmartDevice, Handheld, and Consumer applications
