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 can be independently negated under user control for subtraction of products.
