NJW1186 NJW1186 5.1ch Surround Processor s GENERAL DESCRIPTION The NJW1186 NJW1186 is an Surround Processor for 5.1ch speaker system regenarating Center, Surround and Subwoofer channel signal from normal stereo signal input. The NJW1186 NJW1186 contains Passive Matrix circuit, BPF for center channel, LPF for subwoofer, simulated stereo function for surround channel and trimmers for each channel. 2 All of internal status and variables are controlled by I C BUS. It is suitable for TV set, Home Theater and the others. s PACKAGE OUTLINE NJW1186M NJW1186M s FEATURES q Operating Voltage 7.5 to 13V 2 q I C BUS Interface q Passive Matrix Surround Circuit q Trimmer & BPF for Center Channel q Trimmer & LPF for Subwoofer Channel q Trimmer & Simulated Stereo Function for Surround Channel q Bi-CMOS Technology q Package Outline DMP20 DMP20 s BLOCK DIAGRAM Lout Rout Lin Rin LSout Simulated Stereo RSout BPF Cout LPF Passive Matrix SWout + + V+ Vref GND Bias Control SDA SCL CSU CCE CSW -1- NJW1186 NJW1186 s PIN CONFIGURATION 1 Filter 20 2 SWfilin CSW 19 3 SW'out CCE 18 4 RSout 5 Rin V+ 16 6 Lin GND 15 7 LSout SCL 14 8 C'out SDA 13 9 CFilin CSU 12 10 No. SWout Cout Vrefin 17 SYMBOL PS 11 FUNCTION 1 SWout Subwoofer Channel Output 2 SWFilin LPF for Subwoofer Channel 3 SW'out Subwoofer Channel Trimmer Output 4 RSout Right Surround Channel Output 5 Rin Right Channel Input 6 Lin Left Channel Input 7 LSout Left Surround Channel Output 8 Center Channel Trimmer Output CFilin BPF for Center Channel 10 Cout Center Channel Output 11 PS 12 CSU Pop Noise Reduction for Left Surround & Right Surround Channel Trimmer 13 SDA I C Bus Data Input 14 SCL I C Bus Clock Input 15 GND Ground 16 V 17 Vrefin Reference Voltage Stabilizing Capacitor 18 CCE Pop Noise Reduction for Center Channel Trimmer 19 CSW Pop Noise Reduction for Subwoofer Channel Trimmer 20 -2- C'out 9 Filter Filter for Surround Channel + Filter for Simulated Stereo 2 2 Power Supply NJW1186 NJW1186 s ABSOLUTE MAXIMUM RATING (Ta=25°C) PARAMETER SYMBOL RATING UNIT 15 + V Supply Voltage V Power Dissipation PD 350 mW Maximum Input Voltage VIM 0 to V+ V Operating Temperature Range Topr -40 to +85 °C Storage Temperature Range Tstg -40 to +125 °C TEST CONDITION MIN.
