of Block Operations 1.

Crystal Oscillator Circuit and Timing Generator The clock required for internal operations is generated by connecting a crystal and condensers as shown in the diagram below.

The IC will also operate when a system clock is input from an external source through the XI pin (pin 1

TC9470FN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC9470FN Σ-∆ Modulation DA Converter with Built-in 8-Times Oversampling Digital Filter/Dynamic Digital Bass Boost/Analog Filter The TC9470FN is a second-order Σ-∆ modulation system 1-bit DA converter incorporating an 8-times oversampling digital filter, dynamic digital bass boost function for use with compressor operations and an analog filter developed for digital audio equipment.

Because the IC includes an analog filter, it c
