NJW1167/A AUDIO PROCESSOR with Subwoofer Output ■ GENERAL DESCRIPTION The NJW1167/A is a sound processor with subwoofer output includes all of functions processing audio signal for TV, such as tone control, balance, volume, mute, and AGC functions. Also the NJW1167/A includes the LPF for subwoofer output and bass boost function. The original surround system reproduces natural surround sound and clear vocal orientation. 2 All of internal status and variables are controlled by I C BUS interface. ■ PACKAGE OUTLINE NJW1167V NJW1167AL ■ FEATURES ● Operating Voltage 7.5 to 13V NJW1167FJ2 ● 3ch Output(Lch, Rch, Subwoofer ch) / 2ch Output(Lch, Rch) ● LPF Filter (Adjustable cut off frequency by external parts) ● AGC Circuit (It reduces volume difference among input sources.) 2 Adjustable AGC boost level by external parts and AGC compression level by I C BUS ● eala(NJRC Original Surround System) ● Simulated Stereo 2 ● I C BUS Interface ● Bi-CMOS Technology ● Package Outline NJW1167: SSOP32, QFP32-J2 NJW1167A: SDIP32 ■ BLOCK DIAGRAM AGC1 SS-FIL VOL1 IN a TONE VOL1 OUTa SCL SDA ADR VOL2 I2 CBUS Interface eal a & Simulated Stereo AGC IN b TONE TONE -Ha -La LF1 LF2 LF3 LPF TONE VOL2 Trimmer PORT1 PORT0 AUX1 AUX0 VOL2 Bias AGC2 SR-FIL TONE TONE -Hb -Lb OUTb OUTw CVA CVB CVW CTH CTL CSR GND V+ Vref -1- NJW1167/A ■PIN CONFIGURATION SSOP32, SDIP32 No. Symbol 1 INa INb 32 2 SR-FIL LF2 31 3 SS-FIL LF3 30 4 TONE-Ha LF1 29 5 TONE-La TONE-Hb 28 6 OUTW TONE-Lb 27 7 OUTa OUTb 26 8 AGC1 AGC2 25 9 AUX0 CVA 24 10 AUX1 CVB 23 11 PORT0 CVW 22 12 PORT1 CTH 21 13 ADR CTL 20 14 SDA CSR 19 15 SCL Vref 18 16 GND V+ 17 Function No. Function 1 INa Ach input terminal 17 V+ Supply voltage terminal 2 SR-FIL Surround filter terminal 18 Vref Reference voltage terminal 3 SS-FIL Simulated stereo filter terminal 19 CSR DAC output terminal for surround control 4 TONE-Ha Ach tone control (treble) filter terminal 20 CTL DAC output terminal for tone control (bass) 5 TONE-La Ach tone control (bass) filter terminal 21 CTH DAC output terminal for tone control (treble) 6 OUTw Subwoofer output terminal 22 CVW Bch DAC output terminal for LPF trimmer 7 OUTa Ach output terminal 23 CVB Bch DAC output terminal for volume and balance 8 AGC1 24 CVA Ach DAC output terminal for volume and balance 25 AGC2 AGC boost level setting terminal 26 OUTb Bch output terminal 27 TONE-Lb Bch tone control (bass) filter terminal Bch tone control (treble) filter terminal 10 AUX1 11 PORT0 AGC attack and recovery time setting terminal Auxiliary 3 values voltage output terminal (0.0V, 2.5V, 5V) Auxiliary 2 values voltage output terminal (0.0V, V+) Logic input terminal 12 PORT1 Logic input terminal 28 TONE-Hb 13 ADR Slave address setting terminal 29 LF1 LPF filter3 terminal 14 SDA I2C data terminal 30 LF3 LPF filter2 terminal 15 SCL I2C cock terminal 31 LF2 LPF filter1 terminal 16 GND Ground terminal 32 INb Bch input terminal 9 (✳) AUX0 (✳) -2- Symbol The AUX0 terminal should be connected via the protection resistance to 5V device.
