SCT100 series key features ? ocxo performance without the negatve warm-up and input power characteristcs of an ocxo ? compensated for trim effect ? temperature stability as low as 0.02 ppm common applicatons ? test instrumentaton ? low-power communicaton systems ? gps applicatons ? ocxo replacement sofware-compensated clipped-sine-output tcxo doc. #: SCT100-3p-ss rev: - functonal descripton the sct-series tcxo combines esterline research and designs new patent-pending m-sac compensaton technology with state-of-the-art oscillator designs to produce tcxos that outperform many ocxo designs for stability, warm-up tme, and input power. the new sct-series tcxo ofers temperature performance unmatched by any other tcxo on the market today and is ofered in a small-footprint, one-square-inch hermetc package. this product is compensated for trim efect to ensure the temperature stability performance is maintained as the frequency is adjusted by the user to correct for aging (drif over tme). stability degradaton result - ing from frequency adjustment is virtually ignored by most manufacturers, and the m-sac compensaton ensures the low-ppb temperature stability achieved by sct-series tcxos is maintained at frequency adjust - ment extremes.
