The i.MX 8M Plus EVK (8MPLUSLPD4-CPU)uses ABS07-32768KHZ-T for the 32.768KHz crystal oscillator which as a typical drive level of 0.1µW and a maximum of 0.5µW.
However, Table 9 in the Hardware Developer's Guide (IMX8MPHDG Rev 1) states that the crystal requires a drive level of at least 1µW. Is this requirement a typo, and is it meant to say 0.1µW ?
Thanks Rita,
Isn't that the old Hardware Developers Guide revision?
You attached
IMX8MPHDG Rev 0, 03/2021, which says the drive strength must be at least 0.5µW.
I have
IMX8MPHDG Rev 1, 03/2024, which says drive strength must be at least 1µW.
