AM5718-HIREL: Hysteresis of rtc_osc_xi_clkin32

Yuya

Part Number: AM5718-HIREL

Hi, everyone

I have a question about rtc_osc_xi_clkin32 of AM5718-HIREL.

In Table 4-2 of the datasheet, rtc_osc_xi_clkin32 has no hysteresis.
However, in Table 5-14 of the datasheet, the hysteresis of rtc_osc_xi_clkin32 is 150mV or more.

which one is correct?

Hi,

I will check in our internal design and specifications, and get back with you.

Thank you for your patience - still digging. I am reaching out to the analog design team - it appears the information we seek is locked away in the design database.

Confirmed the 32K osc input pins do not have hysteresis, and the spec listed in table 5-14 should not be there. The input hysteresis spec only applies to the high-frequency clock inputs. This will be removed in a future revision. Thank you for raising this!

Regards,
Mike
