Ge n e ra l De s c rip t io n  
Fe a t u re s  
The MAX2140 complete receiver is designed for satellite  
d ig ita l a ud io ra d io s e rvic e s (SDARS). The d e vic e  
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 c omp le te SDARS ra d io, 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.

The fractional-N PLL allows a very small frequency  
step, making possible the implementation of an AFC  
loop . Ad d itiona lly, the re fe re nc e is p rovid e d b y a n  
external XTAL and on-chip oscillator. A reference buffer  
output is also provided.
