Subject: [TN] impedance value very high
I have a puzzling question for you impedance experts:
A customer is asking for a PCB characteristic impedance for a single
trace to be 332 Ohms +/- 5%.
I've never seen a requirement for an impedance to be this high. Has
anyone here seen this before? HyperLynx is choking on this.
Thank you in advance for your input, it is greatly appreciated.
