Complete SDARS Receiver  
General Description  
Features  
The MAX2140 complete receiver is designed for satellite  
digital audio radio services (SDARS). The device  
includes a fully monolithic VCO and only needs a SAW at  
the IF and a crystal to generate the reference frequency.  
♦ Integrated Receiver, Requires Only One SAW  
Filter  
♦ Self-Contained RF AGC Loop  
♦ Differential I/Q Interface  
To form a complete SDARS radio, the MAX2140  
requires only a low-noise amplifier (LNA), which can be  
controlled by a baseband controller. The small number  
of external components needed makes the MAX2140-  
based platform the lowest cost and the smallest solu-  
tion for SDARS.  
♦ Complete Integrated Frequency Generation  
♦ Bias Supply for External LNAs  
♦ Overcurrent Protection  
♦ Low-Power Standby Mode  
♦ Very Small 44-Pin Thin QFN Package  
The receiver includes a self-contained RF AGC loop  
and baseband-controlled IF AGC loop, effectively pro-  
viding a total dynamic range of over 92dB.  
Channel selectivity is ensured by the SAW filter and by  
on-chip monolithic lowpass filters.  
Ordering Information  
The fractional-N PLL allows a very small frequency  
step, making possible the implementation of an AFC  
loop. Additionally, the reference is provided by an  
external XTAL and on-chip oscillator. A reference buffer  
output is also provided.  
A 2-wire interface (I2C-bus compatible) programs the  
circuit for a wide variety of conditions, providing fea-  
tures such as:

The MAX2140 minimizes the requirement on the base-  
band controller. No compensation or calibration proce-  
dures are required. The device is available in a 7mm ✕  
7mm 44-pin thin QFN package.
