MxFEs reduce power, pc-board space in wireless comm apps

Suited for wireless communications applications, the 12-bit AD9963 and 10-bit AD9961 mixed-signal front-ends (MxFEs) are claimed to use 40% less power (consuming 425 mW at maximum samples rates) and 25% less printed-circuit board area than competing devices without sacrificing performance. Both are pin-compatible devices that integrate two ADC channels with sampling rates to 100 Msamples/s and two DAC channels with sampling rates to 170 Msamples/s.

The MxFEs are also claimed to enable up to 10 dB better ACLR performance than competing devices. Integrated onto the devices are digital interfaces with flexible clocking options. The transmit path is configurable for 1x, 2x, 4x, and 8x interpolation, and the receive path includes a bypassable 2x decimating low-pass filter.

At 1.8 V, transmit path power consumption is less than 100 mW at 170 Msamples and receive path power consumption is less than 350 mW at 100 Msamples/s. Additional features include an SNR of 66.5 dB and sleep and power-down modes.

The AD9963 also integrates auxiliary LDO voltage regulators that allow the device to be powered from a single-supply and further reduce external component count. Both are housed in 72-lead LFCSP packages and support full- and half-duplex data interfaces. See video on product description: http://tiny.cc/MxFEs
