Description
The MAX19708 is an ultra-low-power, mixed-signal analog front-end (AFE) designed for TD-SCDMA handsets and data cards. Optimized for high dynamic performance at ultra-low power, the device integrates a dual 10-bit, 11Msps receive (Rx) ADC; dual 10-bit, 11Msps transmit (Tx) DAC with TD-SCDMA baseband filters; three fast-settling 12-bit aux-DAC channels for ancillary RF front-end control; and a 10-bit, 333ksps housekeeping aux-ADC.
Key Features
- Dual 10-Bit, 11Msps Rx ADC and Dual 10-Bit, 11Msps Tx DAC
- Ultra-Low Power 36.9mW at fCLK = 5.12MHz, Fast Mode 19.8mW at fCLK = 5.12MHz, Slow Mode Low-Current Standby and Shutdown Modes
- Integrated TD-SCDMA Filters with > 55dB Stopband Rejection
- Programmable Tx DAC Common-Mode DC Level and I/Q Offset Trim
- Excellent Dynamic Performance SNR = 55dB at fIN = 1.87MHz (Rx ADC) SFDR = 73dBc at fOUT = 620kHz (Tx DAC)
