MAS6279B
IC FOR 5.00 – 64.00 MHz VCTCXO
• Fifth Order Compensation
• Frequency Stability ± 0.14 ppm
• Wide Frequency Range
• Very Low Phase Noise
• Minimum Operating
Temperature –40 °C
• EEPROM Selectable Output
• Tri State Output
DESCRIPTION
The MAS6279B is an integrated circuit well suited
to build high end VCTCXO for telecommunication.
The trimming is done through a serial bus and the
calibration information is stored in an internal
EEPROM.
To build a VCTCXO only a crystal is required in
addition to MAS6279B. The compensation method
is fully analog, working continuously without
generating any steps or other interference.
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 f_c/2.
• Output waveform selectable by EEPROM:
clipped sine wave or CMOS.
• Possibility to use just a compensation part
APPLICATIONS
• (VC)TCXO for high end
telecommunications systems
• (VC)TCXO for GPS
• (VC)TCXO for Stratum
• (VC)TCXO for Picocell
• (VC)TCXO for Femtocell
