Hi Jabin Tankachan,

   Please refer to the LPCopen USB sample code to configure the PLL0 480Mhz, you can download the code from this link:

LPCOpen Software for LPC43XX|NXP 

  Please choose the MCB4357 sample code, and refer to the USB sample code, this lpcopen USB sample code also use 480Mhz clock.

Besides, there also a PLL calculation tool for your reference, you can get the data of the PLL register settings.

Have a great day,
Kerry
