MAS6287 超宽温度范围 VCTCXO IC

MAS6287 是一款 VCTCXO IC，针对从 –40 °C … +85 °C 到非常宽的 –60 °C … +125 °C 温度范围的高稳定性 VCTCXO 和 TCXO。该器件采用获得专利的全模拟温度补偿方法，可在 –60 °C … +125 °C 下实现 ±0.5 ppm 典型值、–40°C … +105 °C 和 ±0.1 ppm 典型值的 ±0.2 ppm 频率稳定性典型值为 –40 °C … +85 °C。小尺寸使其也适用于小模块。

它的典型功耗在 40MHz 时仅为 2.5 mA。1 kHz 时 -134 dBc/Hz 的低相位噪声允许 MAS6287 在要求苛刻的应用中使用。针对负载或电源电压变化的频率稳定性非常好。工作电源电压范围为 2.8V 至 3.6V。它具有可编程分频器功能，允许输出频率范围为 8 MHz 至 52 MHz。输出波形可选择正弦波或CMOS。MAS6287 可用作裸片或小型 QFN-10 3x3x0.75mm 封装。

MAS6287 is a VCTCXO IC targeted for high stability VCTCXOs and TCXOs from –40 °C … +85 °C up to very wide–60 °C … +125 °C temperature range. The device uses patented fully analog temperature compensation method making it possible to achieve frequency stabilities of ±0.5 ppm typ at –60 °C … +125 °C, ±0.2 ppm typ at –40°C … +105 °C and ±0.1 ppm typ at –40 °C … +85 °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 sine wave or CMOS. The MAS6287 is available as die or in a small QFN-10 3x3x0.75mm package.
