The MAX5863 ultra-low-power, highly integrated analog

front end is ideal for portable communication equipment

such as handsets, PDAs, WLAN, and 3G wireless termi-

nals. The MAX5863 integrates dual 8-bit receive ADCs

and dual 10-bit transmit DACs while providing the high-

est dynamic performance at ultra-low power. The ADCs’

analog I-Q input amplifiers are fully differential and

accept 1V

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 f

and f

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 fea-

ture dual 10-bit resolution with 73dBc SFDR, and 61dB

SNR at f

The ADCs and DACs operate simultaneously or indepen-

dently for frequency-division duplex (FDD) and time-divi-

sion duplex (TDD) modes. A 3-wire serial interface

controls power-down and transceiver modes of opera-

tion. The typical operating power is 22.8mW at f

7.5Msps with the ADCs and DACs operating simultane-

ously 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 ana-

log 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.
