Interpolation Filters
Each video output on the TMC2192 is digitally filtered with
sharp-cutoff low-pass interpolation filters. These filters
ensure that the frequency band above base-band video and
below the pixel frequency (f
S
/4 to 3f
S
/4, where f
S
is the
PXCK frequency) are sufficiently suppressed.
Since these are fixed-coefficient digital filters, their filter
characteristics depend upon clock rate.

Control Registers for this section
The TMC2192 contains a selectable X/sin(X) filter prior to
each DAC. The X/sin(X) filter boosts the high frequency
data to negate the sin(X)/X roll-off associated with D/A con-
verters.
