QT2001 MCXO
MICROCOMPUTER COMPENSATED CRYSTAL OSCILLATOR
5.0Vdc - 10MHz

CORPORATION
QT2001 MCXO (Revision -, October 2008)
Description
Q-Tech’s microcomputer compensated crystal oscillator,
MCXO, uses a high stability overtone SC-cut crystal with mi-
croprocessor controlled compensation. The self-temperature
sensing resonator, using a dual-mode oscillator, virtually
eliminates thermometry related errors. As a result, all basic
TCXO and OCXO limitations are overcome or significantly
reduced in the MCXO.
