MAS6282 Datasheet PDF

Micro Analog systems MAS6282

The MAS6282 is an integrated circuit well suited to build VCTCXO for mobile communication. The trimming is done through a serial bus and the calibration information is stored in an internal PROM. This means no rework for trimming is needed.

DESCRIPTION

Temperature calibration is achieved in three calibration temperatures only. This means no rework for trimming is needed. To build a VCTCXO only a crystal is required in addition to MAS6282. The compensation method is fully analog, working continuously without generating any steps or other interference. Output is true sine wave resulting in lower harmonics than with clipped sine wave output.
