PX-702 High Temperature Crystal Oscillator PX-702 Vectron offers a small footprint High Temperature Ceramic SMD Crystal Oscillator (PX-702) product platform for extreme environment applications. In addition to its wide operating temperature range, PX-702 HTXO is also ideal for high shock & vibration applications. PX-702 HTXO is also designed to exceed 3000g shock and 36g vibration levels of the demanding MIL-STD-883 requirements. Vectrons vertical integration in the following technical areas ensures the ability to design and manufacture state of the art high temperature frequency control products: BAW & SAW Design & Fabrication to produce high quality resonators. RF Oscillator Circuit Design. Established 250C High Temperature Electronics Packaging Expertise. Established 250C High Temperature Electronics Assembly & Test Expertise. Environmental Screening. Vectrons manufacturing processes, from quartz resonator fabrication to oscillator electronics assembly and test, are painstakingly controlled via ISO and SPC procedures. Vectron fabricates high temperature quartz resonators using proprietary manufacturing processes designed specifically for high temperature and harsh environment applications. In order to ensure high reliability in the field, critical electrode metallization and testing processes are conducted inside state-of-the-art Class 1K cleanrooms, while oscillator assembly is conducted in Class 10K cleanrooms. All high temperature oscillators are 100% tested before delivery.
