Protoboards & High Frequencies
Jul 18, 2005
5 Replies
If I wanted to use a MCU or clocked PLD with a protoboard, what would be the maximum frequency I could work at without the protoboard's stray capacitance mucking things up?
If I were to use a chip (PIC) that had an internal timer rather than an external crystal or ceramic resonator, would I be able to work with higher frequencies (> 4MHz)?

20MHz works? That's great. I was under the impression that if you wanted to go higher than 4, you had to use a PWB. That'll save me some money.

higher
Regularly run 20Mhz PICs on protoboard with no problems. Faster logic and the protoboard has been good to 100MHz. Analogue stuff is usually OK to say 20-30MHz. It's the wire link connections that's the main killer of performance. regards john

I was talking about protoboards and not the vector boards in the second link.
