IDT announces fourth-generation FemtoClock NG for XO and VCXO replacement

SAN JOSE, USA: Integrated Device Technology Inc. (IDT) has announced a new family of quad-frequency programmable clock oscillators leveraging IDT’s fourth-generation FemtoClock NG technology. The new devices offer industry-leading performance as a highly flexible silicon-based solution for crystal oscillator (XO) and voltage-controlled crystal oscillator (VCSO) replacements.

The IDT 8N3Q001, 8N4Q001, 8N3QV001 and 8N4QV001 are quad-frequency programmable clock oscillators leveraging IDT’s silicon-based FemtoClock NG technology. They offer excellent high-frequency and low-phase noise performance for demanding telecommunication, computing, networking and storage applications. These devices enable system designers to reduce complexity and cost by replacing up to four XOs with a single IDT quad-frequency clock oscillator.

The devices feature programmable output frequencies from 15.476 MHz up to 1,300 MHz, giving engineers the flexibility to reprogram and generate new frequencies without the long delays typically associated with crystal oscillators. IDT’s custom FemtoClock NG products can be received within 6 to 8 weeks on average, instead of the 14 to 16 weeks of typical custom XOs.

“We’ve built upon our timing leadership to offer a high-performance and highly integrated device to replace outdated fixed-frequency XOs in the $4B frequency control market,” said Fred Zust, VP and GM, Timing and Synchronization Division, IDT. “Our new clock oscillators integrate multiple programmable frequencies into a single package, enabling our customers to simplify their board designs and eliminate the lead-time risks posed by fixed-frequency products in fast-paced design cycles.”

IDT’s new clock oscillators feature four factory-programmed frequencies that can be customized for different applications and reconfigured by a standard I2C interface. This makes it easy for engineers to reprogram the devices in the lab or on-the-fly in the application. The fourth-generation FemtoClock NG technology operates at phase noise levels below 500 femtoseconds with power supply rejection ratio (PSRR) better than -80 dBc, making it well-suited for high-speed finely tuned systems.
