SiT5302: High Frequency Stratum 3 MEMS VCTCXO

4pin

The SiT5302 is the industry's only high frequency Stratum 3 VCTCXO. It extends frequency coverage up to 220MHz, a dramatic enhancement over legacy quartz OCXOs and TCXOs that offer 5-10 standard frequencies at less than 60 MHz. Combined with low voltage operations, large pull range, and programmable features such as configurable rise/fall time, this device enables new opportunites for engineers to simplify design, improve system performance, reduce board size and lower cost without sacrificing lead time. In addition, its superior shock and vibration resistance, and 2 FIT reliability are 20 times better than quartz, and are ideal for high reliability telecom and networking infrastructure applicaitons.
