System Clock
The TMC2250A operates from a single system clock
input. All timing specifications are referenced to the
rising edge of clock.

Mode Control
The TMC2250A will switch to the configuration
selected by the user (as shown in Table 3) on the
next clock. This registered control is usually static;
however, should the user wish to switch between
modes, the internal pipeline latencies of the device
must be taken into account. Valid data will not be
available at the outputs in the new configuration until
enough clocks in the new mode have passed to flush
the internal registers.
Data presented to the coefficient input ports (KA, KB,
and KC) will update three of the internal coefficient
storage registers, as indicated by the simultaneous
Coefficient Write Enable select, on the next clock.
See Table 4 and the Functional Block Diagram.

Data Input A
Data presented to the 12-bit registered data input
ports A, B, and C are latched into the multiplier input
registers for the currently selected configuration
(Table 3). In all modes except Mode 00, new data are
internally right-shifted to the next filter tap on each
rising edge of CLK.
