hello everyone,
i have a crystal oscillator circuit
iam verymuch confused about the term EQUIVALENT SERIES RESISTANCE.
for an AT CUT crystal operating in fundamental parallel resonant mode is it enough if we just match the load capacitance of the crystal with the circuit?
OR , we too want to consider in matching EQUIVALENT SERIES RESISTANCE of the crystal?
iam going to change the frequency of the oscillator circuit above to
13.25 MHZ by changing the crystal unit , give me some suggestions.
i have a crystal piece with 13.2520 MHZ of fundamental frequency, but i don't know where to find its .i dont know to which manufacture it belong to .
the wordings stamped on the crystal are,
at front side of crystal,
DY-8
13.252083
and at back side of the crystal,
WXL
B/0 05
the crystal is about 1.3 CM in length, and 1 CM in width and the thickness is about 2 CM.with two leads at its base.
how can i get its data?
and how to match with above circuit?
