IDT, a leading provider of essential mixed-signal semiconductor solutions, has introduced the industry’s most accurate all-silicon CMOS oscillators. The IDT3C02 oscillator delivers an industry-leading total frequency error of 100ppm across temperature and voltage variations, offering a reliable alternative to traditional quartz-based oscillators.
Unlike conventional crystal oscillators, the IDT3C02 uses patented CMOS technology in a single-chip design, eliminating the need for mechanical resonators or phase-locked loops (PLLs). This innovative approach allows for a very thin profile while maintaining high precision and stability. The oscillator is ideal for next-generation applications such as Gigabit Ethernet, SAS, SuperSpeed USB (USB 3.0), and PCI Express, providing a low-power and low-jitter solution that supports a wide range of system designs.
Fred Zust, Vice President and General Manager of IDT Communications, highlighted the significance of this development: “The IDT3C02 represents a major leap forward in timing technology. As a true alternative to crystal oscillators, it expands our leadership in the field and offers customers a more flexible and efficient option.â€
The IDT3C02 leverages a standard CMOS process with a programmable architecture, allowing for various configuration options to meet different application needs. One of its key features is the factory-programmable operating frequency, which reduces lead times and simplifies the use of special or rare frequencies compared to traditional quartz solutions.
In terms of power efficiency, the device consumes less than 2.5mA under no-load conditions and achieves a state-of-the-art phase noise of -140dBc/Hz at a 1MHz carrier offset. It is available in a compact 5 x 3.2mm package compatible with standard quartz crystal sizes, using a cost-effective MSL1 plastic IC package instead of a ceramic hermetic one.
Additionally, the IDT3C02 includes a low-power standby mode of 200nA (typical) and a fast start-up time of 100μs (typical), making it highly suitable for power-sensitive applications. Its all-silicon design eliminates moving parts, offering superior resistance to shock and vibration. This makes it a robust choice for environments where reliability and durability are critical.
