change crystal to tcxo

Hi

I used OMAPL137EVM. there is 24MHZ crystal in this board. the CLKMODE in the gel file is zero (CLKMODE = 0). i attached the "pic1" that show pll settings in gel file.

i want to changed the 24MHZ crystal to 19.2MHZ TCXO :

1 ) i want that all of devices (nand flash,sdram,...) on the board worked correctly in this situation. for this situation i changed CLKMODE from zero to one in gel file ( CLKMODE = 1 ). i attached the "pic2" that show new pll settings in this situation. 

This changes are correct and enough ?

2 ) I want to used pspdrivers example in this situation. i added  below line to the tcf file:

bios.GBL.CLKIN = 19200;
bios.GBL.CLKOUT = 297.6000;
bios.CLK.INPUTCLK = 19.2000;

This changes are correct and enough ?

Thank you
