MMPF0100: Discrepancy between Dual-lite Sabre and AN4536

[Sebster]

Hello Community,

Per AN4536 and datasheet, the F0 variant column identifies a selected voltage of 3.3V on SW2 whereas the SABRE ref design identifies the voltage as 3.0V.   Can you confirm is this MMPF0100 variant default is 3.0V, or has the PMIC used in SABRE Dual-Lite been altered from the F0 pre-programming?

Same oberversation for SABRE Dual-Lite the SW4 output at 1.8V, whereas the datasheet table indicates a voltage of 3.15V for F0. Again this must have been altered right?

Thanks

Seb

Hi Sebastien

yes, SW voltages can be changed at run time.

MMPF0100 F0 (preprogrammed)  has SW2 3.3V, SW4 3.15
