The IFM register sets the main frequency divide ratio
for the IF PLL. The IFR register sets the reference fre-
quency divide ratio. The IF VCO frequency can be
determined by the following:
IF VCO frequency = f
REF

(IFM / IFR)
where f
REF
is the external reference frequency.
The operational control register (OPCTRL) controls the
state of the MAX2369. See Table 3 for the function of
each bit.
The configuration register (CONFIG) sets the configura-
tion for the IF PLL and the baseband I/Q input levels
See Table 4 for a description of each bit.
The test register is not needed for normal use.
Power Management
Bias control is distributed among several functional
sections and can be controlled to accommodate many
different power-down modes as shown in Table 5.
The shutdown control bit is of particular interest since it
differs from the SHDN pin. When the shutdown control
bit is active (SHDN_BIT = 0), the serial interface is left
active so that the part can be turned on with the serial
bus while all other functions remain shut off. In contrast,
