An IC modulation processor (28) may be configured to operate in a single chip mode to accommodate baud rates up to a maximum clock rate for the processor (28) and in a dual chip mode to accommodate baud rates in excess of the maximum clock rate. The IC modulation processor (28) performs digital processing on a communication signal which conveys an input data stream (22). A pulse shaping filter (54-57) is provided following a phase mapper (50). The pulse shaping filter (54-57) is implemented as a pair of half-filters. Pulse shaping is distributed between two IC modulation processors (28) in the dual chip mode. An interpolator (86) and linearizer (106) follow the pulse shaping filters (54-57).
