AM3358: Absolute maximum ratings for XTAILIN (OSC0) input

Felipe Gonzalez Escaray

Part Number: AM3358

Could you help me with a parameter? I need to know which is the maximum High-level input voltage for XTAILIN (OSC0). I'm using as a source an oscillator.

Thanks

Hi,

OSC0 input is powered from the VDDS_OSC power rail, which is 1.8V. Absolute maximum input voltage for this input is VDDS_OSC +0.3V. Absolute minimum is -0.5V. It's important to note that no external voltage should be applied to OSC0 pin before the VDDS_OSC supply has fully ramped-up and stabilized. This means that you should either use an external oscillator powered from VDDS_OSC, or place an external 1.8V buffer powered from VDDS_OSC.
