PTH04T240W: Output capacitors design

FRANK1

Part Number: PTH04T240W

Hi sir,

Is the required output capacitors needed by the PTH04T240WAD have to be near by?
Can I use the caps required by the FPGA to satisfy PTH04T240WAD need?
The PTH04T240WAD is about is 5 inches from the FPGA capacitors.

Thank u.

Hi Mark,

Yes, the required minimum output capacitance needs to be close to the PTH's output. Use the total capacitance on the output bus for calculating stability limits and the TT resistor.
