TCXO / VCXO

Bomar Crystal produces TCXOs and VCXOs with a wide range of options. They are available in HCMOS or clipped sinewave. Frequency stability is available to 1 ppm within an operating temperature range of -40° to +85° C. Extremely low jitter is standard. Packages include Thru-hole (full and half size), metal SMD gull wing, or 11.4 x 9.6 MM ceramic SMD packages.

Call: 1-(800)526-3935, or Contact Us to order.



All TCXOs are available RoHS approved and excellent for Test Equipment, Networking Equipment.
