19-0529; Rev 1; 9/06 KIT ATION EVALU E L B AVAILA 10-Bit, 45Msps, Full-Duplex Analog Front-End General Description Features - Dual 10-Bit, 45Msps Rx ADC and Dual 10-Bit, 45Msps Tx DAC - Ultra-Low Power 91.8m W at f CLK = 45MHz, FD Mode 79.2m W at f CLK = 45MHz, Slow Rx Mode 49.5m W at f CLK = 45MHz, Slow Tx Mode Low-Current Standby and Shutdown Modes - Programmable Tx DAC mon-Mode DC Level and I/Q Offset Trim - Excellent Dynamic Performance SNR = 54.1d B at f IN = 5.5MHz (Rx ADC) SFDR = 70.3d Bc at f OUT = 2.2MHz (Tx DAC) - Three 12-Bit, 1µs Aux-DACs - 10-Bit, 333ksps Aux-ADC with 4:1 Input Mux and Data Averaging - Excellent Gain/Phase Match ±0.03° Phase, ±0.02d B Gain (Rx ADC) at f IN = 5.5MHz - Multiplexed Parallel Digital I/O - Serial-Interface Control - Versatile Power-Control Circuits Shutdown, Standby, Idle, Tx/Rx Disable - Miniature 56-Pin Thin QFN Package (7mm x 7mm x 0.8mm) The MAX19713 is an ultra-low-power, highly integrated mixed-signal analog front-end (AFE) ideal for wideband munication applications operating in full-duplex (FD) mode. Optimized for high dynamic performance and ultra-low power, the device integrates a dual 10-bit, 45Msps receive (Rx) ADC; dual 10-bit, 45Msps transmit (Tx) DAC; three fast-settling 12-bit aux-DAC channels for ancillary RF front-end control; and a 10-bit, 333ksps housekeeping aux-ADC. The typical operating power in FD mode is 91.8m W at a 45MHz clock frequency. The Rx ADCs feature 54d B SINAD and 72.2d Bc SFDR at 5.5MHz input frequency with a 45MHz clock frequency. The analog I/Q input amplifiers are fully differential and accept 1.024VP-P full-scale signals. Typical I/Q channel matching is ±0.03 phase and ±0.02d B gain. The Tx DACs feature 70.3d Bc SFDR at f OUT = 2.2MHz and f CLK = 45MHz. The analog I/Q full-scale output voltage range is ±400m V differential. The output DC mon-mode voltage is selectable from 0.71V to 1.06V. The I/Q channel offset is adjustable to optimize radio lineup sideband/carrier suppression....
