Hi, all:- There does not seem to be any typical or otherwise figures on clock frequency vs. DC bias resistor on this part. The datasheet (DS40300B-page 98) refers to the "Electrical Specification" section, which doesn't seem to have anything in it, only min/max frequency numbers with no indication of what resistances would be required to produce those frequencies. Anyone have even one data point for this? Eg. with a 100K resistor, I get XX MHz clock. (There are also a couple of mistakes/omissions on the Pinout description overview (page 11), none of which have made their way to the errata yet.) Best regards, Spehro Pefhany --"it's the network..."
