Description

The MIC1700 is a complete reconstruction filter solution for high definition set-top boxes.

The MIC1700 has two independent component inputs (YP_R P_B or RGB) selectable via a 2-to-1 multiplexer, and a separate S- video input (Y/C). Component channel filters have a select- able cutoff frequency (8MHz or 36MHz) to support both standard (SD) and high definition (HD) applications. S-video filters of MIC1700 have fixed cutoff (8MHz) to support legacy composite applications. In addition, S-video channels are summed to provide a filtered CV output for an RF modulator or VCR. All inputs are DC-coupled with a 0V to 1V peak-to-peak range. All outputs of MIC1700 are designed to drive 2V peak-to-peak into AC-coupled 150 loads. This supports 1V peak-to-peak into a 75 load with a 75 series source terminator.

Filters MIC1700 have 6^th order near Butterworth characteristics with cutoffs of 8MHz (SD and CV) and 36MHz (HD). These characteristics are chosen to provide good passband flat- ness with sufficient stop band attenuation and minimal group delay distortion.

The MIC1700 operates from a 5VDC supply.
