MEMS oscillators boast 100 fs typical phase jitter
The very low phase jitter and adaptable output frequency of these oscillators significantly reduce bit error rate (BER) in 10 gigabit Ethernet (10GbE) switches, routers, and other related networking equipment.
The IDT 4H MEMS oscillators feature a differential LVDS / LVPECL output and the lowest phase jitter in their product class (100 fs at 1.875 to 20MHz and sub-300 fs at 12 kHz to 20 MHz), satisfying the low-jitter chipset requirements of high-performance networking applications.
Integrated frequency margining capability enables customers to fine-tune the oscillator frequency during operation in the application by up to ±1000 ppm, minimizing BER and facilitating margin testing. Unlike competitive MEMS devices that only offer fixed frequencies, IDT’s device allows hundreds of offset frequencies that can be generated after the selection of any base frequency up to 625 MHz – even on final production systems. The 4H MEMS oscillators are currently sampling to qualified customers and are available in standard 7.0 x 5.0, 5.0 x 3.2 and 3.2 x 2.5 mm VFQFPN packages.
