EURO QUARTZ
DESCRIPTION
CXO oscillators consist of a miniature quartz crystal and a CMOS/TTL
compatible hybrid circuit in a low-profile, small footprint ceramic
package. In addition to the conventional solder or epoxy electrical
connection techniques, the CXO oscillator's bond pads on the topside
of the unit allow it to be connected electrically in a hybrid assembly
using wire bonds.
