Multi-Output SAW Oscillator Maintains Low-Jitter

Multiple-output SAW oscillator integrates a complete timing chain, a SAW oscillator, frequency dividers and fan-out buffers, while still achieving low jitter performance.

Boasting the world's first multiple-output SAW oscillator, the MG-7050 family, Epson Electronics is seeking to allow networking, storage and computing equipment manufacturers to reduce size, power and cost without compromising performance or reliability. Using proven high-reliability SAW technology, the oscillator family achieves low jitter (120 fs rms @ 156.25 MHz and 50 fs @ 700 MHz integrated phase jitter 12 kHz - 20 MHz) suitable for the most demanding applications. Integrating a complete timing chain, a SAW oscillator, frequency dividers and fan-out buffers, the family still achieves the same jitter performance as the company’s XG-2121 and XG-2102 series of SAW oscillators. Also included is a programmable frequency divider so a single device can provide two frequencies. The oscillators are most suitable for network equipment such as GbE, fiber channel, SAS, PCI express server, storage, router, switch and optical transport networks. To accommodate a variety of systems, the MOSOs are offered in 2- and 4-output configurations, and LV-PECL, LVDS (100 to 700 MHz) and HCSL (100 to 200 MHz) output types. Samples of the MG-7050 family MOSOs (5 x 7 x 1.6 mm packages) are available now.
