Note 1:
Frequency division by two is selected by PROM bit DIV: 0=no division, 1=div by 2
Thus IC output frequency range is 6.5 MHz – 40 MHz.
Note 2:
Depending on crystal pulling
Note 3:
VDD±5%
Note 4:
R=10 k ±10%, C=10 pF±10%
Note 5:
0.8 V / 1.0 V output is selected by PROM bit AMPL: 0=0.8 Vpp, 1=1.0Vpp
Note 6:
Typically C10 = 3.1 pF at CDACF=0, CDACC=0
Note 7:
Not measured in production testing; guaranteed by design
Note 8:
Max power consumption is 8 mW when V
