hi all .I am using ECS 2100AX 20 Mhz oscilltor with pic16f874a.But the oscillator is not working properly. when i have measured its oscillation frequency ,it is showing few of khz. Any idea how to geyt rid of this problem.
bdw . I have connected output pin of oscillator with osc1 of pic microcontroller and left the osc2 pin. I have used config -hs mode in my program. as it is a 4 pin oscillator i havnt used any capacitors across it.
