SC9256 PLL FOR DIGITAL TUNING SYSTEM


Posted on Feb 6, 2014

The SC9270C/ SC9270D is a complete DTMF receiver integrating both the bandsplit Filter and digital decoder functions. The Filter section uses switched capacitor techniques for high- and low-group Filters and dial-tone rejection. Digital counting techniques are employed in the decoder to detect and decode all 16 DTMF tone-pairs into a 4-bit code. E
