Tel : Fax : email : ACT1525CT/AT 0044 (0)118 979 1238 0044 (0)118 979 1283 [email protected] TCXO The ACT1525CT family is a range of HCMOS Digitally Temperature Compensated Crystal Oscillators whereas the ACT1525AT family is a range of AHCMOS DTCXOs. Whilst operating, the oscillator frequency is adjusted to cancel out the change due to temperature. A microcontroller performs the elaborate control algorithm which is individually calibrated to each crystal. Trimmer adjustment is provided to compensate for aging.
