I got a question.
I wanna configure an external clock circuit in AVR.
but, To select the crystal,11.0592MHz
I found load capacitance of crystal.
the load capacitance -> C_Load, capacitance on PCB line(1pF~2pF), and
internal capacitance in IC -> C_in
i found out that i need to match X-tal's C_Load to C_IC + C_stray.
and I put 30pF capacitor for external
I can count C_load = (30+Cin)/2+C_strary .
I couldn't find the internal capacitance of atmega128
and what crystal is recommended.
I'm gonna use 11.0592MHz crystal, ATS
WHat crystal of capacity should i use ??
