[原创] Cypress CY2941x可编PLL晶振15MHz－2．1GHz解决方案

Cypress公司的CY2941x/CY2942x系列是可编基于PLL的晶体振荡器解决方案,具有灵活的输出频率从15MHz到2.1GHz和极好的抖动性能,工作电压1.8V-3.3V,主要用在通信应用如OTN,SONET/SDH, xDSL, GbE,网络,无线基础设备以及测试和仪器仪表于高速数据转换器.本文介绍了CY2941x/CY2942x系列主要特性,逻辑框图,以及评估板CY3676框图,电路图和材料清单.

The CY2941x/CY2942x is a programmable PLL-based crystaloscillator solution with flexible output frequency options. It is fieldor factory-programmable for any output frequency between15 MHz and 2.1 GHz. Other frequency options can be configuredwith the I2C interface.Using advanced design technology, itprovides excellent jitter performance across the entire outputfrequency range, working reliably at supply voltages from 1.8 Vto 3.3 V for ambient temperatures from–40℃ to +105℃.Thismakes it ideally suited for communications applications (forexample,OTN,SONET/SDH,xDSL,GbE,networking,wirelessinfrastructure), test and instrumentation applications, andhigh-speed data converters.Additionally, the VCXO functionenables use of the CY2941x/CY2942x series in applicationsrequiring a clock source with voltage control, and in discreteclocking solutions for synchronous timing applications
