ECS-VXO-73/VXO-75
SERIES
SMD VCXO'S
The ECS-VXO-73 (3.3V) and ECS-VXO-75
(5.0V) are miniature VCXO'S voltage
controlled crystal oscillators with tri-state in
a ceramic SMD package. The low profile
package is ideal for todays advanced portable
PC and instrumentation applications.
FEATURES
• 3.3V & 5.0V versions
• 1.6 mm profile
• Low power consumption
• Tri-State
• Seam welded package
• Tape & Reel (1,000 pcs STD)
• PbFree/RoHS Compliant
