The MSP432P401 data sheet specifies an HF crystal ESR range of 15-30 ohms. I have not been able to find the Geyer crystal specified in the data sheet at any U.S. distributor. I would like to find an alternative component available from Mouser if possible, but I can't find a 48MHz crystal from any manufacturer specifying ESR less than 50 ohms at 48MHz. The Geyer data sheet does not specify ESR, only a series resonance value, which is 50 ohms at 48MHz.
Mouser stocks 185 different SMD 48MHz crystals meeting my operating temperature range, and none of them meet the TI spec for ESR. I can't believe TI would make a microcontroller that will only work with a Geyer crystal, but I'm not finding any other options. I need the oscillator to start up reliably from -40 to +70 C. Any advice?
