Miniature VCTCXO IC with +/-0.14 ppm frequency stability
Micro Analog Systems have today announced the introduction of a miniature VCTCXO IC, the MAS6279, which is primarily intended for the most stable TCXO and VCTCXO modules. The device uses fully analog compensation method making it possible to achieve +/-0.14 ppm or better frequency stability. Because of its small size the reduction of module size is possible.
MAS6279 has typical power consumption only 1.3 mA. Low phase noise of -136 dBc/Hz at 1 kHz allows the use of the MAS6279 in demanding applications. The frequency stability against load or supply voltage changes is excellent. It has programmable divider function allowing the output frequency range of 5 MHz to 64 MHz. Output wave form can be selected from sine wave or CMOS.
Key features:
- Very small size,
- Minimal current consumption,
- Wide operating temperature range,
- Very low phase noise,
- Minimum operating temperature –40 °C,
- Oscillator frequency output selectable by EEPROM direct or fc/2,
- Output waveform selectable by EEPROM: clipped sine wave or CMOS.
MAS6279 is delivered as die or in small QFN-10 3 x 3 package. Volume production has already started and samples are available. Price for 1000 pcs is USD 2.73 each.
