ESR for HFXO conflict on
On the EFM32GG395 DATASHEET page 23 Table 3.10 HFXO it indicates a ESR Max <=50 for 48Mhz yet according to AN0016 (Oscillator Design Considerations) page 12...list 3 chips that have >50 ohms for ESR - see table 5.1. Which is correct? I designed and built a board with one of these higher ESR crystals (ABM11-48.000-D2X-T3), and in a peer review they caught this as an issue because of the datasheet. Should I change crystal? Thanks.
