Frequency Management International manufactures a wide variety of crystal clock oscillators (XOs). Our
oscillator products are in standard and custom thru-hole oscillator packages and SMD (surface mount)
clock oscillator packages. The FMI crystal clock oscillator product line includes low voltage
differential signaling (lvds), positive-referenced emitter-coupled logic (pecl),
sinewave & clipped sinewave, hcmos & ttl clock, low-voltage, voltage controlled
and temperature compensated oscillators. Applications for crystal closk oscillators
include computer peripherals, industrial instrumentation, LAN/WAN,
optical networks, process controls, telecommunications and wireless products.
