Low jitter MEMS oscillator from IDT with integrated frequency margining feature

Integrated Device Technology has unveiled differential MEMS oscillators with 100 femtosecond (fs) typical phase jitter performance and integrated frequency margining capability. IDT claims this is the first MEMS oscillator to have such a low phase jitter. The low phase jitter and adaptable output frequency of this mems oscillator help in reducing bit error rate (BER) in 10 gigabit Ethernet (10GbE) switches, routers, and other related networking equipment.

The IDT 4H performance MEMS oscillators feature a differential LVDS / LVPECL output and are available in multiple package sizes including the smaller 3225 (3.2 x 2.5 mm).

“IDT’s latest series of MEMS oscillators build upon the standard 4M and enhanced 4E oscillator series’ to address the demanding performance requirements of 10GbE and networking applications,” said Christian Kermarrec, vice president and general manager of the Timing and Synchronization Division at IDT. “As the leader in timing solutions, we equip our customers with the highest performance parts and innovative features to facilitate the development of their next-generation products. We are pleased to see many OEMs choosing IDT over MEMS start-up suppliers for the experience and technical innovation that IDT provides.”

“Cloud computing and storage infrastructure is growing rapidly with almost 50% of servers and storage clusters shipping with 10GbE. High performance MEMS oscillators enable a lower bit error rate in enterprise computing and storage infrastructure and offer much better reliability at the same time,” said Jérémie Bouchaud, director and principal analyst for MEMS and sensors at IHS.

IDT says its integrated frequency margining capability enables customers to employ a technique known in the industry as ‘plus-PPM clocking’. This technique clocks systems at a slightly higher frequency, allowing OEMs to reduce BER and resulting packet losses in networking applications. IDT claims its MEMS oscillators offer 40 times better reliability than quartz with no activity dips, no zero-time failures, higher jitter resistance to EMI, and excellent shock and vibration resistance, making them an ideal upgrade solution for traditional quartz-based oscillators.

Pricing and Availability: The IDT 4H MEMS oscillators are currently sampling to qualified customers and are available in standard 7.0 x 5.0 mm, 5.0 x 3.2 mm and 3.2 x 2.5 mm VFQFPN packages. Most standard frequencies are readily available. Custom frequencies can be configured by request. For more information, visit www.idt.com/go/MEMS.
