TMC2246A Applications in Digital

Filtering

Unrestricted access to all input ports of the TMC2246A

allows the user considerable flexibility in realizing numerous

digital filter architectures. Figure 6 illustrates how the device

may be utilized as a flexible high-speed FIR filter with the

ability to modify all of the filter coefficients dynamically or

to store a fixed set if desired.

Longer filters, with more taps, are realized by including an

external adder (such as the common 74381 type) to cascade

multiple TMC2246As. Alternatively, two additional taps and

a cascading adder are available in the Fairchild TMC2249A

Digital Mixer.
