LVDS/LVPECL piezoelectric MEMS oscillator from IDT with <1 picosecond Jitter

Integrated Device Technology has announced the CrystalFree piezoelectric MEMS (pMEMS) LVDS / LVPECL oscillators for high performance communications, consumer, cloud, and industrial applications. IDT's oscillators operate with less than one picosecond of phase jitter in compact packaging.

The IDT 4M series high-performance LVDS / LVPECL oscillators leverage IDT's patented CrystalFree pMEMS resonator technology, enabling IDT to rapidly factory-program the desired output frequency without the need to fine-tune expensive crystals. In addition, because the nominal resonator frequency of pMEMS is much higher than quartz crystal, 4M oscillators are able to achieve higher frequencies at lower cost without sacrificing critical performance. The 4M series is the first of a broad portfolio of MEMS-based devices from IDT that will provide customers with convenient, accurate, low-jitter timing references.

"As the leader in timing, our customers have been waiting for IDT's pMEMS technology to expand into high-performance applications such as communications - a significant segment of the $4B frequency control market," said Fred Zust, vice president and general manager of the timing and synchronization division at IDT. "IDT's patented pMEMS resonator technology combines the strong electromechanical coupling of the piezoelectric material with the stability and low damping of single-crystal silicon, allowing us to create convenient and cost-effective XO replacements with unparalleled performance and reliability. These products complement our award-winning solid-state oscillators to offer a comprehensive frequency control portfolio to replace quartz-based devices in a growing number of market segments."

Features:
1. Frequency accuracy: ±50 ppm
2. Industrial temperature range: -40°C to 85°C
3. Support low voltage differential signaling (LVDS) and low voltage positive emitter coupled logic (LVPECL) at frequencies up to 625 MHz
4. Available in 7.0 x 5.0 mm (7050) and 5.0 x 3.2 mm (5032) sizes
5. Pin to pin compatible with traditional XOs

The IDT 4M oscillators are currently sampling to qualified customers and are available in many configurations based on frequency, voltage, output types and industry standard packages.

IDT claims these are the world's First Piezoelectric MEMS Oscillators
