CRYSTAL TYPE = EURO QUARTZ
Note (1):
The phase non linearity is defined as: DPh = | -2 ff2 + ff1 + ff3 |
where ffx is the input-output phase difference at the frequency fx (x = 1,2,3)
Table 4.
Note (2): The 3th harmonic (57KHz) at the output (pin12) must be less than -40dB in respect to the input signal plus gain.
