[原创] IDT 5L35023VersaClock 3S可编时钟发生器解决方案

IDT公司的5L35023是VersaClock® 3S可编时钟发生器,1.8V工作,采用3 PLL架构,每个PLL可单独可编程,允许有多达6个频率输出,内置主动省功耗特性(PPS),性能-功耗平衡(PPB),降过冲技术(ORT)和极低功耗DCO以及动态频率控制(DFC),扩展频谱时钟有更低的系统EMI,I2C接口,主要用在嵌入计算设备,替代消费类应用晶振,以及SmartDevice,手持设备和消费类电子.本文介绍了5L35023主要特性,输出指标,框图以及5L35023 USB开发板主要功能布局和电路图.

The 5L35023 is a member of the VersaClock® 3S programmableclock generator family with 1.8V operation voltage, and isdesigned for industrial, consumer, and PCI Express applications.The device features a 3 PLL architecture design; each PLL isindividually programmable and allowing up to 6 unique frequencyoutputs.

The 5L35023 has built-in features such as Proactive PowerSaving (PPS), Performance-Power Balancing (PPB), OvershotReduction Technology (ORT) and extreme low power DCO. Aninternal OTP memory allows the user to store the configuration inthe device without programming after power-up, then program the5L35023 again through the I2C interface.

The device has programmable VCO and PLL source selection,allowing power-performance optimization based on the applicationrequirements.

5L35023主要特性:

▪ Configurable OE pin function as OE, PD#, PPS or DFC controlfunction..
