CORPORATION
MICROCOMPUTER COMPENSATED CRYSTAL OSCILLATOR
3.3Vdc - 5 to 100MHz, 32.768kHz and 1PPS
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.
