PRODUCT SPECIFICATION
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.
