Mixed-Signal Front End ICs save space and reduce power in wireless communications equipment
The 12-bit AD9963 and 10-bit AD9961 MxFEs use 40 percent less power and 25 percent less printed-circuit board area than competing devices without sacrificing performance. These MxFEs are especially effective for cost-sensitive wireless equipment, such as femtocell and picocell base stations that require highly integrated dual transmit-and-receive functions.
The 12-bit AD9963 and 10-bit AD9961 are pin-compatible, low-power MxFEs that each integrate two ADC (analogue-to-digital converter) channels with sample rates to 100 MSPS (mega samples per second) and two DAC (digital-to-analogue converter) channels with sample rates to 170 MSPS. The new MxFEs enable up to 10 dB better ACLR (adjacent-channel leakage ratio) performance than competing devices, easing design and filtering requirements while consuming less power.
Also integrated onto the devices are digital interfaces with flexible clocking options. These MxFEs have five auxiliary analogue channels consisting of two 12-bit DACs, two 10-bit DACs and a 12-bit ADC. The ADC may be used to measure and monitor multiple points, both internal and external. The transmit path is configurable for 1x, 2x, 4x and 8x interpolation, and the receive path includes a by-passable 2x decimating low-pass filter. The AD9963 also integrates auxiliary LDO (low dropout) voltage regulators that allow the device to be powered from a single-supply and further reduce external component count.
