SM802XXX中文资料Clock Generators UltraLow Jitter Products数据手册Microchip规格书

描述 Description

The SM802XXX series is a high performnace family of devices that provide an extremely low-noise timing solution for applications such as (1-100) Gigabit Ethernet, SONET, Wireless base station, Satellite communication, Fibre Channel, SAS/SATA and PCI-e. It is based upon a unique PLL architecture that provides less than 250fs phase jitter.The devices operate from a 2.5V or 3.3V power supply and synthesize up to 8 different combinations (LVPECL, LVDS, HCSL) of differential or 16 single ended output clocks. The devices accept an external reference clock or crystal input.Configure a part to your specific requirements with the CLOCKWORKS CONFIGURATOR tool.
