... The 24-bit adder/subtractor is followed by an accumulator and 16-bit input port which allows the user to cascade multi- ple TMC2249As. A new 16-bit accumulated output is avail- able every clock the maximum rate of 60 MHz. All inputs and outputs are registered except the three-state out- put enable, and all are TTL compatible ...

... TMC2249A Functional Description The TMC2249A performs the summation of products described by the formula: S(N+5) =A(N-ADEL) B(N-BDEL) (-1 NEG2(N) C(N-CDEL) D(N-DDEL) (-1 CAS(N+3 FT) where ADEL through DDEL range from pipe delays. All inputs and controls utilize pipeline delay registers to maintain synchronicity with the data input during that clock, ...

... The effective filter speed is calculated by dividing the clock rate by one-half the number of taps implemented. Alternatively, non-symmetric FIR filters can be implemented using the TMC2249A in a similar fashion. Here, a shift reg- ister is used to delay the incoming data fed to the A input by an amount equal to one-half the length of the filter (the length of the A delay register). Table 4. FIR Filtering – ...

... X cade input. Quadrature Modulation Y The TMC2249A can also be used to advantage as a digital- domain complex frequency synthesizer, as demonstrated in Figure 7. Here, orthogonal sinusoidal waveforms are generated digi- tally in the TMC2330A Coordinate Transformer. These quadrature phase coefficients are then multiplied with two input signals, such as digitized analog data ...
