Piezoelectric MEMS oscillators focus on high-performance applications

May 09, 2012 // By Paul Buckley
Integrated Device Technology has unveiled what the company claims is the first CrystalFree piezoelectric MEMS (pMEMS) LVDS/LVPECL oscillators for high-performance communications, consumer, cloud, and industrial applications.

The oscillators operate with less than one picosecond of phase jitter in compact industry-standard packaging, making them an ideal replacement for traditional six-pin crystal oscillators (XOs).
 
The 4M series high-performance LVDS/LVPECL oscillators use the company’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.
 
The 4M oscillators operate with ±50 ppm frequency accuracy over the wide industrial temperature range of -40°C to 85°C. The devices support low-voltage differential signaling (LVDS) and low-voltage positive emitter-coupled logic (LVPECL) at frequencies of up to 625 MHz, meeting the stringent requirements of most communications, networking and high-performance computing applications. In addition to 7.0 x 5.0 mm (7050) sizes, the pMEMS oscillators are available in small 5.0 x 3.2 mm (5032) standard plastic packages to save cost and minimize the application footprint in densely populated enclosures. By design, they are pin-to-pin compatible with traditional XOs, making them an ideal upgrade replacement solution.

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