MAX5866 Ultra-Low-Power, High-Dynamic-Performance, 60Msps Analog Front End

The MAX5866 ultra-low-power, highly integrated Analog front end is ideal for portable Communication equipment such as handsets, PDAs, WLAN, and 3G Wireless terminals. The MAX5866 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 0.2 and amplitude matching is 0.05dB. The ADCs feature 48dB SINAD and 70.1dBc spurious-free dynamic range (SFDR) at fIN = 25MHz and fCLK = 60MHz. 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 matching is 0.4 and gain matching is 0.1dB. The DACs also feature dual, 10-bit resolution with 64.2dBc SFDR, at fOUT = 6MHz and fCLK = 60MHz.
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 96mW at fCLK = 60MHz with the ADCs and DACs operating simultaneously in transceiver mode. The MAX5866 features an internal 1.024V Voltage Reference that is stable over the entire operating power-supply range and temperature range. The MAX5866 operates on a +2.7V to +3.3V Analog power supply and a +2.7V to +3.3V digital I/O power supply for Logic compatibility. The quiescent current is 12mA in idle mode and 1A in shutdown mode. The MAX5866 is specified for the extended (-40C to +85C) temperature range and is available in a 48-pin thin QFN package. See a parametric table of the complete family of pin-compatible AFEs.
