Miniature VCTCXO IC exhibits frequency stability.

Press Release Summary:



Delivered as die or in QFN-10, 3 x 3 package, MAS6279 is primarily intended for stable TCXO and VCTCXO modules. Use of fully analog compensation method makes it possible to achieve ±0.14 ppm or better frequency stability. Power consumption is 1.3 mA typ, minimum operating temperature is -40°C, and phase noise is -136 dBc/Hz at 1 kHz. Programmable divider function allows output frequency range of 5–64 MHz, and output wave form can be selected from sine wave or CMOS.



Original Press Release:



Micro Analog Systems Releases New VCTCXO IC.



Targeted for ultra stable VCTCXO and TCXO modules.



Helsinki, Finland – Micro Analog Systems Oy today announced MAS6279, a miniature VCTCXO IC 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.



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, Ex works Micro Analog Systems Oy, Finland.
