IDT 4H MEMS Oscillators Feature 100fs Phase Jitter Performance

Integrated Device Technology (IDT) 4H MEMS oscillators

Integrated Device Technology introduced their 4H MEMS oscillators. They are the industry’s first differential MEMS oscillators with 100 femtosecond (fs) typical phase jitter performance and integrated frequency margining capability. 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.

The IDT 4H performance MEMS oscillators feature a differential LVDS / LVPECL output and the lowest phase jitter in their product class (100 fs @ 1.875 – 20 MHz and sub-300 fs @ 12kHz – 20 MHz). Integrated frequency margining capability enables designers to fine-tune the oscillator frequency during operation in the application by up to ±1000 ppm, minimizing BER and facilitating margin testing. IDT’s 4H MEMS oscillators are available in multiple package sizes including the smaller 3225 (3.2 x 2.5 mm) to save board space and cost in densely populated applications.

The extremely low phase jitter and adaptable output frequency of IDT’s high-performance oscillators significantly reduce bit error rate (BER) in 10 gigabit Ethernet (10GbE) switches, routers, and other related networking equipment.

The 4H MEMS oscillators leverage IDT’s patented piezoelectric MEMS (pMEMS) resonator technology to provide a high-frequency source of unparalleled performance and reliability. IDT 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.
