MAX19711 datasheet




The MAX19711is an ultra-low-power, highly integrated mixed-signal analog front-end (AFE) ideal for CDMA communication applications operating in full-duplex (FD) mode. Optimized for high dynamic performance and ultra-low power, the device integrates a dual 10-bit, 11Msps receive (Rx) ADC; dual 10-bit, 11Msps transmit (Tx) DAC with CDMA baseband filters; three fast-settling 12-bit aux-DAC channels for ancillary RF front-end con
trol; and a 10-bit, 333ksps housekeeping aux-ADC. The typical operating power in FD mode is 37.5mW/42.7mW at a 4.915MHz/11MHz clock frequency. The Rx ADCs feature 54.8dB SNR and 74.2dBc SFDR at 1.875MHz input frequency with an 11MHz clock frequen
cy. The analog I/Q input amplifiers are fully differential and accept 1.024VP-Pfull-scale signals. Typical I/Q channel matching is ±0.01°phase and ±0.01dB gain.
