General Description
The MAX2753 is a self-contained voltage-controlled oscil-
lator (VCO) intended for use in 2.4GHz radios that utilize a
low-IF or zero-IF architecture. It combines a fully integrat-
ed oscillator and output buffer in a miniature 8-pin μMAX
package.
The inductor and varactor elements of the tank are inte-
grated on-chip, greatly simplifying application of the part.
The only required external components are a couple of
supply bypass capacitors. The MAX2753 provides direct
connection to the VCO tuning voltage input and the VCO
buffer output. The tuning voltage input range is +0.4V to
+2.4V, and the oscillator frequency tuning range is factory
adjusted to provide guaranteed limits. The output signal is
buffered by an amplifier stage (internally matched to 50
)
to provide higher output power and isolate the device from
load impedance variations. In addition, the MAX2753 pro-
vides differential outputs.
The MAX2753 operates over a +2.7V to +5.5V supply volt-
age range. Internal regulation of the oscillator supply volt-
age eliminates the need for an external LDO regulator for
the VCO. The MAX2753 also provides a digitally controlled
shutdown mode to permit implementation of sophisticated
power-supply management. In shutdown, the supply cur-
rent is reduced to less than 1μA.
