MEMS oscillators with integrated frequency margining capability offer lowest jitter

The 4H MEMS oscillators with integrated frequency margining capability is claimed to have the lowest phase jitter of 100 fs typical at 1.875 to 20 MHz and sub-300 fs at 12 kHz to 20 MHz – further enabling reduced BER in 10 gigabit Ethernet (10GbE) switches, routers, and other related networking equipment. Integrated frequency margining capability enables customers to fine-tune the oscillator frequency during operation in the application by up to ±1,000 ppm, minimizing BER and facilitating margin testing.

Additional specifications include a 50- to 625-MHz frequency range and 2.5- to 3.3-V operation. The 4H MEMS oscillators use the company's patented piezoelectric MEMS (pMEMS) resonator technology – claimed to enable 40x better reliability than quartz with no activity dips, no zero-time failures, higher jitter resistance to EMI, and excellent shock and vibration resistance. Housed in standard 7.0 x 5.0 mm, 5.0 x 3.2 mm and 3.2 x 2.5 mm VFQFPN packages, the oscillators feature a differential LVDS/LVPECL output.
