QT2010 MCXO Q-TECH 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 microprocessor 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.
