7.5Msps, Ultra-Low-Power  
Analog Front-End  
General Description  
Features  
♦ Dual 10-Bit Rx ADC and Dual 10-Bit Tx DAC  
The MAX19700 is an ultra-low-power, mixed-signal ana-  
log front-end (AFE) designed for TD-SCDMA handsets  
and data cards. Optimized for high dynamic perfor-  
mance at ultra-low power, the MAX19700 integrates a  
dual 10-bit, 7.5Msps receive (Rx) ADC, dual 10-bit,  
7.5Msps transmit (Tx) DAC with TD-SCDMA baseband  
filters, and three fast-settling 12-bit aux-DAC channels  
for ancillary RF front-end control. The typical operating  
power in Tx-Rx FAST mode is 36.3mW at a 5.12Msps  
clock frequency.  
♦ Ultra-Low Power  
36.3mW at fCLK = 5.12Msps, Fast Mode  
19.8mW at fCLK = 5.12Msps, Slow Mode  
Low Standby and Shutdown Current  
♦ Integrated TD-SCDMA Filters with >55dB  
Stopband Rejection  
♦ Excellent Dynamic Performance  
SINAD = 54.9dB at fIN = 1.87MHz (Rx ADC)  
SFDR = 76.5dBc at fOUT = 620kHz (Tx DAC)  
The Rx ADCs feature 54.9dB SINAD and 78dBc SFDR  
at a 1.87MHz input frequency with a 7.5Msps sample  
frequency. The analog I/Q input amplifiers are fully dif-  
♦ Excellent Gain/Phase Match  
ferential and accept 1.024V  
full-scale signals.  
P-P  
0.22ꢀ Phase, 0.02dB Gain (Rx ADC) at  
Typical I/Q channel matching is 0.22ꢀ phase and  
0.02dB gain.  
fIN = 1.87MHz at -0.5dBFS  
♦ Three 12-Bit, 1µs Aux-DACs  
♦ Single-Supply Operation  
♦ Multiplexed Parallel Digital I/O  
♦ Serial-Interface Control  
The Tx DACs with TD-SCDMA lowpass filters feature  
-3dB cutoff frequency of 1.27MHz and >55dB stop-  
band rejection at f  
= 4.32MHz. The analog I/Q  
IMAGE  
full-scale output voltage range is selectable at 410mV  
or 500mV. The output common-mode voltage is selec-  
table from 0.9V to 1.4V and the I/Q channel offset is  
adjustable. The typical I/Q channel matching is  
0.05dB gain and 0.16ꢀ phase.  
♦ Versatile Power-Control Circuits  
Shutdown, Standby, Idle, Tx-Rx Disable  
♦ Miniature 48-Pin Thin QFN Package  
The Rx ADC and Tx DAC share a single, 10-bit parallel,  
high-speed digital bus allowing half-duplex operation  
for time-division duplex (TDD) applications. A 3-wire  
serial interface controls power-management modes  
and the aux-DAC channels.  
(7mm x 7mm x 0.8mm)  
Pin Configuration  
The MAX19700 operates on a single +2.7V to +3.3V  
analog supply and +1.8V to +3.3V digital I/O supply.  
The MAX19700 is specified for the extended (-40ꢀC to  
+85ꢀC) temperature range and is available in a 48-pin,  
thin QFN package.
