DESCRIPTION
T1220 series Microprocessor-Compensated Crystal Oscillators
(MCXOs) provide OCXO performance in a TCXO. The part is
packaged in either a standard through-hole 14 pin DIL equivalent
package or a SMD version. Ability to operate in severe environments
makes this an ideal high-performance TCXO.
