NOTES:
C1 and C2 should be based on manufacturer’s specification.
X1 and X2 parasitic capacitance IS 1-2pF AND 3-5pF, respectively.
GAIN:
PHASE: at 4MHz 272 to 276 ; at 8MHz 272 to 276
C1 and C2 should be chosen according to the
crystal manufacturer’s specification.
C1 and C2 values will include any parasitic
capacitance of the wiring.
