TMC2249A
Overview
The TMC2249A is a high-speed digital arithmetic circuit consisting of two 12-bit multipliers, an adder and a cascadeable accumulator. All four multiplier inputs are simultaneously accessible to the user, and each includes a userprogrammable pipeline delay of up to 16 clocks in length.
- 60 MHz input and computation rate Two 12-bit multipliers Separate data and coefficient inputs Independent, user-selectable pipeline delays of 1 to 16 clocks on all input ports Separate 16-bit input port allows cascading or addition of a constant User-selectable rounded output Internal 1/2 LSB rounding of products Fully registered, pipelined architecture Available in 120-Pin CPGA, PPGA, MPGA or MQFP
