LF2249 DEVICES INCORPORATED 12 x 12-bit Digital Mixer LF2249 DEVICES INCORPORATED 12 x 12-bit Digital Mixer DESCRIPTION The LF2249 is a high-speed digital mixer comprised of two 12-bit multipliers and a 24-bit accumulator.
All multiplier inputs are user accessible, and each can be updated on every clock cycle.
The LF2249 utilizes a pipelined architecture with fully registered inputs and outputs and an asynchronous three-state output enable control for optimum flexibility.
Independent input register clock enables allow the user to hold the data inputs over multiple clock cycles.
Each multiplier input also includes a user-selectable 1-16 clock pipeline delay.
The output of each multiplier ...
