SPECIFICATIONS
fVCXO = 122.88 MHz single-ended, REFA and REFB on differential at 30.72 MHz, fVCO = 3932.16 MHz, doubler is off, channel control
low power mode off, divider phase =1, unless otherwise noted. Typical is given for VDD = 3.3 V ± 5%, and TA = 25°C, unless otherwise
noted. Minimum and maximum values are given over the full VDD and TA (40°C to +85°C) variation, as listed in Table 1.
