(Q1) Required queries about IMX6 ultra lite processor and its Errata. Need help for clarification

Crystal/Oscillator (24Mhz) queries:

  • The below schematics captured from NXP reference design, it’s followed two difference clock circuits.
    a)24 crystal (Y501)
    b)24 MHz clock(Y503)

 

1.Do we really required crystal as well as oscillator to make processor work?
2.Why we need two different clock circuit and logical connection in design?
3.Is PMIC_STBY_REQ signal will used to make Processor Standby while pulling the MOSFET line to ground?

 

 

We are looking cost effective solution for our design, so we prefer 24MHz crystal along with 16PF load caps only. Is this work for new silicon version 1.1 processor chip? Please refer our design snapshot below,

Figure1:

We would like use simple crystal without affecting functionality. 

Could you please validate this design?

We have seen in NXP community, they posted that there was some errata issue (ERR009455).
