Overview
LF2242 DEVICES INCORPORATED DEVICES INCORPORATED 12/16-bit Half-Band Interpolating/ Decimating Digital Filter DESCRIPTION The LF2242 is a linear-phase, halfband (low pass) interpolating/ decimating digital filter that, unlike intricate analog filters, requires no tuning.
The LF2242 can also significantly reduce the complexity of traditional analog anti-aliasing prefilters without compromising the signal bandwidth or attenuation.
This can be achieved by using the LF2242 as a decimating post-filter with an A/D converter and by sampling the signal at twice the rate needed.
Likewise, by using the LF2242 as an interpolating pre-filter with a D/A converter, the corresponding analog reconstruction post-filter circuitry can be simplified.
The coefficients of the LF2242 are fixed, and the only user programming required is the selection of the mode (interpolate, decimate, or passthrough) and rounding.
The asynchronous three-state output enable control simplifies interfacing to a bus.
