‘Most accurate’ cmos oscillator
1 min read
IDT has announced what it believes to be the most accurate all silicon cmos oscillator, which has a total frequency error across temperature, voltage and other factors of 100ppm. Using patented technology, the IDT3C02 replaces quartz crystal based oscillators with a monolithic cmos ic, without the need for a mechanical frequency source or a PLL.
Designed specifically to work with next generation storage, datacom and connectivity interfaces, the device is a low power, low jitter replacement for general purpose quartz crystal oscillators.
"The IDT3C02 is a major breakthrough in the timing industry," said Fred Zust, general manager of IDT's communications division. "An ideal choice over crystal alternatives, it expands on the all silicon cmos oscillators in wafer forms announced earlier this year."
The IDT3C02 generates frequencies on chip without relying on a piezoelectric or mechanical resonator. Built on a standard cmos process, the device uses a programmable architecture and supports configuration to suit a range of applications.
In addition, the oscillator has an analogue core which consumes less than 2.5mA. With a typical standby power consumption of 200nA and a typical start up time of 100µs, the device is suitable for use in power sensitive designs, allowing frequent power cycling for further power savings.
