NJRC NJW1107FC3 Dolby pro logic surround decoder with discrete 5.1ch input Datasheet

NJW1107
PRELIMINARY
Dolby Pro Logic Surround Decoder with Discrete 5.1ch Input
■ GENERAL DESCRIPTION
The NJW1107 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 NJW1107 is most suitable for AV
amplifier with discrete 5.1ch inputs for Dolby Digital.
In addition to Dolby Pro Logic Surround function, the NJW1107
performs easily other surround function such as Hall, Live, Disco and
others, and echo and microphone mixing functions for Karaoke.

■ NOTICE
The NJW1107 includes Auto-Reset circuit. The NJW1107 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.
