SAW OSCILLATOR COMPETES FOR CLOCK DUTIES AGAINST ENTRENCHED CRYSTAL OSCILLATORS

摘要

Crystal oscillators dominate the clock circuit space because of their superior precision, stability, and low cost. But Epson Toyocom offers some attractive alternatives. Its EG-4101/4121A surface-acoustic wave (SAW) oscillator has the stability and performance to challenge crystal oscillators in wireless basestations and local-area network (LAN) and storage-area network (SAN) applications.rnThe unique, patented EG-4101/4121A features temperature frequency stability and phase noise performance that fit a variety of communications applications. It operates at a fundamental frequency in the 100- to 700-MHz range.
