Dear SI-List Can anybody comment on the effect of AC-coupling capacitors used on a pair of matched length (200 MHZ HSTL) clocks? I have duplicated the capacitor placement (near the driver), ie the trace lengths are all matched, but the capacitors themselves are not matched parts. Any guesses as to how much skew could be induced? The capacitors are 470 pF 10% X7R 0603 type. The value was chosen for minimal impedance around 200 and 400 MHz. -Paul -------------------------------------------- N.
