Overview

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 can be independently negated under user control for subtraction of products.
The sum of the products can also be internally rounded to 16 bits during the accumulation process.
A separate 16-bit input port connected to the accumulator is included to allow cascading of multiple LF2249s.
