LM3880: Schematic review

Part Number: LM3880

Could you review the attached schematic?

Please note U29 is a placeholder for now.

  • I understand VCC and EN cannot be tied together

As for U53, VCC is expected to come up before EN as VCC_1V8_FPGA will go thru additional regulator.

What would be the best way to implement U29?

Use a cap to EN?

Thanks,

Andrew
