Dolby Pro Logic Surround Decoder with Discrete 5.1ch Input
s GENERAL DESCRIPTION The NJW1107A is a Dolby Pro Logic Surround Decoder with discrete 5.1ch input. It includes Dolby Pro Logic Surround decoder, 4 master volumes, 4 level trimmers and 6 switches. The 6 switches choose internal Dolby Pro Logic Surround Decoder or discrete 5.1ch inputs. The NJW1107A is most suitable for AV amplifier with discrete 5.1ch inputs for Dolby Digital. In addition to Dolby Pro Logic Surround function, the NJW1107A performs easily other surround function such as Hall, Live, Disco and others, and echo and microphone mixing functions for Karaoke. s PACKAGE OUTLINE

s NOTICE The NJW1107A includes Auto-Reset circuit. The NJW1107A requires both analog power supply (AVCC) and digital power supply (DVDD). Internal digital circuits are initialized by AVCC. The internal reset signal is released after treset period (0.7sec. < treset < 1.3sec.). * Power-on Sequence 1. Turn the AVCC on first. 2. Provide the DVDD within 0.7 seconds after the AVCC turns on. 3. Keep the voltage of DVDD below the voltage of AVCC always. 4. Wait for 1.3 seconds and over after the AVCC turns on. 5. Transmit the control data from MCU.
