Hi everyone,
I know that I'm asking about two different types of component, but I have two questions and did not want to start two consecutive threads.
First, let's start with thyristors.
I've bought a couple of thyristors to use them as signal triggers, but I can't get them to work!
First, I know that thyristors do have an anode, a cathode and a base. But when looking into the documentation of the one I have (BRX49), I find that:
Pin 1: anode
Pin 2: anode
Pin 3: cathode
So how do I connect it???
Also, I've tried to do the following circuit, assuming pin 2 to be the gate, which does not work (even though I've measured the voltage at the gate, and it goes from <200 mV to ~2V when it detects a signal). However, the led stays off...
About PLL's, how do they work internally? I know they are used as frequency multipliers and to sync the clock on "large" chip, but what else are they used for?
Could also anyone please explain how do you use a PLL as a frequency multiplier? (A real world example with a part number would be greatly appreciated!).
Thanks a lot!

Gonzalo
