Notes
1. All VDD and VSS connections must be made externally to the same power supply.
2. Equivalent to discharging a 100 pF capacitor via a 1.5 k series resistor with a rise time of 15 ns.
3. Equivalent to discharging a 200 pF capacitor via a 2.5 H series inductor.


Description

The SAA7345 incorporates the CD signal processing functions of decoding and digital filtering. The device is equipped with on-board SRAM and includes additional features to reduce the processing required in the analog domain.

Supply of this Compact Disc IC does not convey an implied license under any patent right to use SAA7345 in any  Compact Disc application.
