USING PATENTED TECHNOLOGY, a new CMOS oscillator promises to replace quartz-crystal-based oscillators with a monolithic CMOS integrated circuit (IC) at frequency accuracy of 100 ppm and better. The IDT3C02 oscillator utilizes a programmable architecture and supports various configuration options to suit a range of applications. For example, frequency of operation is programmed by the factory. The IDT3C02 is designed with an analog core, which typically consumes less than 2.5 mA (unloaded). The oscillator provides -140 dBc/Hz phase noise at 1 MHz offset from carrier. Typically, it features a 200-nA low-power standby mode and startup time of 100 s. Because the device contains no moving elements and generates frequencies electronically instead of using mechanical or piezoelectronic resonance, it features superior shock and vibration resistance. Offered in a quartzcrystal- compatible package measuring 5 x 3.2 mm, the IDT3C02 eliminates the need for hermetically sealed ceramic packaging and instead utilizes low-cost and thinprofile MSL1 plastic IC packaging. P&A: sampling; $0.73 each in 1000Q.
