General Description
The MAX5864 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 MAX5864 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 1VP-P full-scale signals. Typical I-Q channel
phase matching is
±0.1° and amplitude matching is
±0.03dB. The ADCs feature 48.5dB SINAD and 69dBc
spurious-free dynamic range (SFDR) at fIN = 5.5MHz and
fCLK = 22Msps. The DACs’ analog I-Q outputs are fully
differential with
±400mV full-scale output, and 1.4V com-
mon-mode level. Typical I-Q channel phase match is
±0.15° and amplitude match is ±0.05dB. The DACs also
feature dual 10-bit resolution with 71.7dBc SFDR, and
57dB SNR at fOUT = 2.2MHz and fCLK = 22MHz.
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 42mW at fCLK =
22Msps with the ADCs and DACs operating simultane-
ously in transceiver mode. The MAX5864 features an
internal 1.024V voltage reference that is stable over the
entire operating power-supply range and temperature
range. The MAX5864 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
5.6mA in idle mode and 1A in shutdown mode. The
MAX5864 is specified for the extended (-40°C to +85°C)
temperature range and is available in a 48-pin thin QFN
package.
