Crystal-free oscillators promise low power too
IDT’s new 3LG family of CrystalFree CMOS oscillators guarantees ±50 ppm lifetime frequency accuracy. They are pin-to-pin compatible with existing quartz-based solutions, making the transition to a CMOS-based oscillator and the resulting power savings a seamless proposition.
The devices support low-voltage-differential-signaling (LVDS), low-voltage positive emitter-coupled logic (LVPECL), and host-clock signal level (HCSL) standards for compatibility in a variety of applications. IDT’s 3LG devices are designed using a standard silicon manufacturing process and are offered in industry-standard plastic packaging, resulting in lead time, reliability, and cost of ownership advantages over crystal oscillators.
The 3LG family leverages the fundamental technology of the successful 3CN family of ±100 ppm products that are in volume production today. The new devices generate stable frequencies up to 125 MHz and offer high-performance phase jitter of less than 1 picosecond over the wide frequency offset of 12 kHz to 20 MHz. In addition, semiconductor-grade shock and vibration resistance provides extreme reliability over the lifetime of the device, while the ultra-small, low-profile packages conserve valuable board area in compact designs.
The IDT 3LG CrystalFree ±50 ppm oscillators are currently sampling to qualified customers. The IDT 3CN CrystalFree ±100 ppm oscillators are in full production today, available in industry-standard packages. For high volume applications, IDT’s CrystalFree oscillators can support fast, high-volume production with short lead times, typically fewer than 4 weeks, to support any frequency requirement.
