The B chip specifications are given as typical values.
This is the maximum operating frequency of the CMOS counters. The prescaler value should be chosen to ensure that the RF input is divided down to a frequency that
is less than this value.

The synthesizer phase noise floor is estimated by measuring the in-band phase noise at the output of the VCO, PN
TOT
, and subtracting 20logN (where N is the N divider
value) and 10logF

The phase noise is measured with the EV-ADF411XSD1Z evaluation board and the HP8562E spectrum analyzer. The spectrum analyzer provides the REFIN for the
synthesizer (f

= 10 MHz @ 0 dBm). SYNC = 0; DLY = 0 (Table 7).
