TMS570LS3137: tms570ls3137 VCCPLL2 pin mistake?

Part Number: TMS570LS3137

Hello,

I am trying to develope a pcb for the tms570ls3137 with the BGA footprint. I am based my design routing in the Hercules TMS570LS31X/21X development kit. 

In the pcb schematic, in the MCU power and gnd it is routed a PIN named VCCPLL2. However, I am not able to find the same pin in the datasheet. Does VCCPLL2 really exist, or it is a mistake of the schematic?

    Hello Ander,

    Thanks for pointing this out. I can confirm that this schematic seems to be incorrect according to the available documentation. Pin J14 should be connected to VCC and there is no such pin as VCCPLL2 listed in the documentation of the device. I will communicate this issue to our HDK designer for further consideration for any future updates. Given both supply voltages are the same, I don't believe this mistake will impact the operation of the device on the HDK.
