MAX19700 7.5Msps, Ultra-Low-Power Analog Front-End

The MAX19700 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 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. 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 differential and accept 1.024VP-P full-scale signals. Typical I/Q channel matching is 0.22 phase and 0.02dB gain. The Tx DACs with TD-SCDMA lowpass Filters feature -3dB cutoff frequency of 1.27MHz and >55dB stopband rejection at fIMAGE = 4.32MHz. The Analog I/Q full-scale output voltage range is selectable at 410mV or 500mV. The output common-mode voltage is selectable 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 0.16 phase. 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. 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 (-40C to +85C) temperature range and is available in a 48-pin, thin QFN package. See a parametric table of the complete family of pin-compatible AFEs.
