GENERAL DESCRIPTION

The AD9961/AD9963 are pin-compatible, 10-/12-bit, low power MxFE® converters that provide two ADC channels with sample rates of 100 MSPS and two DAC channels with sample rates to 170 MSPS. These converters are optimized for transmit and receive signal paths of communication systems requiring low power and low cost. The digital interfaces provide flexible clocking options. The transmit is configurable for 1×, 2×, 4×, and 8× interpolation. The receive path has a bypassable 2× decimating low-pass filter.
