2.4GHz Monolithic Voltage-Controlled  
Oscillator with Differential Outputs  
General Description  
Features  
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.  
Guaranteed Frequency Tuning Range: 2400MHz  
to 2500MHz  
Compatible with Low-IF or Zero-IF Radio  
Architectures  
Differential Outputs  
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.
