TMC2242B - Digital Half-Band Interpolating/Decimating Filter

Download the TMC2242B datasheet PDF. This datasheet also covers the TMC2242A variant, as both devices belong to the same digital half-band interpolating/decimating filter family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • TMC2242A and TMC2242B are pin-compatible with TMC2242.
  • User selectable interpolate gain, -6 dB or 0 dB (2242B).
  • 30, 40 and 60 MHz speed grades.
  • User selectable 2:1 decimation, 1:2 interpolation, and equal-rate filter modes.
  • Passband ripple < ±0.01 dB.
  • Stopband rejection 59.4 dB from 0.28 to 0.50 x fs.
  • Cascading two TMC2242A or TMC2242B meets CCIR 601 low-pass filter requirement.
  • Dedicated 12-bit 2's complement input data port.
