TCXO/VCTCXO

TCXO/VCTCXO

Frequency range:1kHz to 800MHz
Temp ranges:-40o to +85oC.

TCXO and VCTCXO

Bomar Crystal produces TCXOs and VCTCXOs with a wide range of options. They are available in LVDS, LVPECL, HCMOS, TTL/CMOS square wave, or clipped sinewave outputs. TCXO and VCTCXO frequency stability is available to 0.5 ppm within an operating temperature range of -40° to +85° C. Extremely low jitter is standard. Packages include Thru-hole (full and half size) or ceramic SMD packages.


All TCXOs are RoHS compliant and excellent for all tight tolerance applications.
