Byte 02 (Default = 3D)
Bits R2, R1, and R0 are the reference divider bits.
The overall reference divide ratio R = 2 x 2 (4 x R2 + 2 x R1 + R0) ,
with the default value of R = 4 (R2 = 0, R1 = 0, R0 = 1).
Bits CP1, CP0 control the charge pump current, with
the default value of ±400μA (Table 4).
Bits OSC2, OSC1, and OSC0 control which of the eight
on-chip VCOs is activated. Default is VCO 5 (101)
(Table 5).
Byte 03 (Default = 7F)
Bit X(0) is unused; default = 0.
Bits F(6)–F(0) set the value of FDAC for the baseband
lowpass filter -3dB cutoff frequency. (see the Baseband
LPFs section).
FDAC = 2 6 ? F(6) + ... +2 0 F(0). (Default FDAC = 127.)
Byte 04 (Default = 02)
Bit ADL is the VCO ADC latch-enable bit. ADL = 1
latches ADC value (ADL = 0, default).
Bit ADE enables VCO tune voltage DAC read. ADE = 1
enables ADC read (ADE = 0, default).
Bit DL sets the differential output drive level for the
MAX2118 (default, DL = 0) (Table 6). This bit is unused
for the MAX2116.
Bits M(4)–M(0) set the value of M counter of lowpass fil-
ter BW control.
M = 2 4 ? M(4) + 2 3 ? M(3) + ... +2 0 M(0). ( Default M = 2.)
