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
