  • TCXO
    1.1 高稳定度可以达到 +/-0.2ppm over -40to +85; +/-2ppm over -55 to +105;
    相位噪声: 50M的TCXO 相噪可以做到-140dBc/Hz @ 1kHz


    1.2 常规的TCXO,满足一般应用,常规稳定度: +/-0.28ppm over -40 to +85。相位噪声:-135dBc/Hz@1kHz @ 20MHz, --常规产品。依据不同的应用场合,可以推荐不同等级的产品。
    常用频点: 10M, 20M,25M,26M,30M,32.768M,40M,50M,80M,100M
    主要封装: 5×7mm, 5×3.2mm,3225, 2520
    应用市场:如卡车载,渔船,卫星终端,手持机,救援设备,应急通信车,火车地铁等,无线抄表,5G物联网,基站,直放站,无线专网通信,公安政府,特殊物资定位,电台,机载通信,北斗终端,GNSS等等


2, OCXO

2.1 高稳定度可以达到0.1ppb级别,10E-10级别,100M的OCXO相噪噪声可以达到-163dBc/Hz @ 1kHz。

2.2 快速启动,fastwarm-up 如100M OCXO,启动75s内可以到0.1ppm。一般OCXO启动要5分钟,即300s。

2.3 低功耗,稳定工作状态功耗仅有0.23W, 一般OCXO工作状态功耗需要2W左右。

2.4 小封装,有DIP14,15×16mm 的小封装OCXO。 大多OCXO都在20×20mm以上,如25×25mm, 36×27mm等。

常用频点:10M,32.768M,40M,50M,80M,100M

应用市场:电力授时,北斗基站,电台,医疗,仪器仪表,直放站,5G基站等等。

LYNNWOOD, WA – Pletronics presents the new PRONTO ® oscillator series offering a 2.0x1.6mm package. The PRONTO ® series state of the art design is able to provide any frequency with lead times in days not weeks. The small form and footprint of the 2.0x1.6mm with endless frequency options up to 200.0MHz and superior jitter performance makes this an ideal device to service all application phases from board design to production volumes. The PRONTO ® series demonstrates outstanding performance in applications, such as 5G, IOT, and Digital Communications. The RMS jitter is specified at 1pS typical making this product series an excellent choice to support designs with reduced jitter budgets. The frequency stability and temperature options range from ±20ppm over an extended OTR of -40to+85°C up to ±50ppm over an operating temperature range up to 105°C.  The PRONTO ® series has a full array of package sizes to suit every design, 2.0x1.6mm, 2.0x2.5mm, 2.5x3.2mm, 5.0x3.2mm, and 5.0x7.0mm
Founded in 1979, Pletronics supplies a wide range of frequency control products to major original equipment manufacturers and contract electronic manufacturers around the world.  The company specializes in low jitter, high frequency, and special application crystal oscillators.
