MAS6287 – Ultra-wide temperature range VCTCXO IC

Micro Analog Systems Oy introduces ultra-wide temperature range VCTCXOIC primarily intended for very wide temperature range VCTCXO and TCXO modules.

MAS6287 is a VCTCXO IC targeted for very wide temperature range VCTCXOs and TCXOs. The device uses patented fully analog temperature compensation method making it possible to achieve ±1 ppm or better frequency stability over ultra-wide temperature range -60 °C … +125 °C. Small size makes it suited also for small modules.

It has typical power consumption only 2.5 mA at 40MHz. Low phase noise of -134 dBc/Hz at 1 kHz allows the use of the MAS6287 in demanding applications. The frequency stability against load or supply voltage changes is excellent. Operating supply voltage range is from 2.8V to 3.6V. It has programmable divider function allowing the output frequency range of 8 MHz to 52 MHz. Output waveform can be selected from clipped sine wave or CMOS.

Samples are available as die or in a small DFN-12 3x3x0.75 mm package. For further information and samples, please contact Micro Analog Systems Oy at
