The MAX5863 ultra-low-power, highly integrated analog front end is ideal for portable communication equipment such as handsets, PDAs, WLAN, and 3G wireless terminals. The MAX5863 integrates dual 8-bit receive ADCs and dual 10-bit transmit DACs while providing the highest dynamic performance at ultra-low power. The ADCs' analog I-Q input amplifiers are fully differential and accept 1VP-P full-scale signals. Typical I-Q channel phase matching is ±0.03° and amplitude matching is ±0.03dB. The ADCs feature 48.5dB SINAD and 69dBc spurious-free dynamic range (SFDR) at fIN = 1.875MHz and fCLK = 7.5Msps. The DACs' analog I-Q outputs are fully differential with ±400mV full-scale output, and 1.4V common-mode level. Typical I-Q channel phase match is ±0.15° and gain match is ±0.05dB. The DACs also feature dual 10-bit resolution with 73dBc SFDR, and 61dB SNR at fOUT = 620kHz and fCLK = 7.5MHz.
The ADCs and DACs operate simultaneously or independently for frequency-division duplex (FDD) and time-division duplex (TDD) modes. A 3-wire serial interface controls power-down and transceiver modes of operation. The typical operating power is 22.8mW at fCLK = 7.5Msps with the ADCs and DACs operating simultaneously in transceiver mode. The MAX5863 features an internal 1.024V voltage reference that is stable over the entire operating power-supply range and temperature range. The MAX5863 operates on a +2.7V to +3.3V analog power supply and a +1.8V to +3.3V digital I/O power supply for logic compatibility. The quiescent current is 3.5mA in Idle Mode™ and 1µA in shutdown mode. The MAX5863 is specified for the extended (-40°C to +85°C) temperature range and is available in a 48-pin thin QFN package.
