Can i use 3.3V Oscillator in XTALI instead of a 24MHZ crystal

hi experts 

in my custom board with imx7d  , i need a clock in FPGA  to use access peripherals 

is there a clock-out in imx7d processor ,  ( i can't find )   if not  could i  use 24MHZ OSC to imx7d XTALI and use the same clock  to supply a clock to FPGA 

in datasheet  , it say "XTALI/XTALO A 24.0 MHz crystal should be connected between XTALI and XTALO." at page 17 

but at page 25,  table 11 "External oscillator or a fundamental frequency crystal appropriately coupled to the internal oscillator amplifier." 

so i don't know  whether i could use OSC or not 

thank you in advance

"External oscillator or a fundamental frequency crystal appropriately coupled to the internal oscillator amplifier."  this is for osc32k
