NJW1160 P R E L I M I N ALY AUDIO PROCESSOR with SOUND ENHANCEMENT and SRS 3D STEREO ■ GENERAL DESCRIPTION The NJW1160 is an audio processor that includes Sound enhancement (BBE) and SRS 3D Stereo. It includes all of the audio signal processing functions for TV such as tone control, balance, volume, mute, and AGC . The SRS 3D stereo technology reproduces 3D stereo surround sound effect using only two speakers. The sound enhancement regenerates high definitive and nearly real sound. 2 All of internal status and variables are controlled by I C BUS interface. ■ PACKAGE OUTLINE NJW1160L NJW1160M ■ FEATURES Operating Voltage 7.5 to 13V 2 I C BUS Interface BBE Sound Enhancement (Low Boost and High Boost: 15dB max.)

AGC (Auto Gain Control) Circuit AGC circuit adjusts the input signal level with Boost/Attenuate circuit. AGC boost the low input signal level and attenuate high input signal level automatically. 2 The AGC flat levels (150mV, 300mV, 400mV and 540mV) are selectable via I C bus. (Refer to the following figure.) AGC Control V+=9V, Vin(Ach+Bch), f=1kHz, Vo(Ach)OUTPUT Rg=600Ω, Ta=25oC 540mV Output Voltage [Vrms] 1 400mV 0.1 AGC ON 300mV 150mV 0.01 0.001 0.001 AGC OFF 0.01 0.1 1 Input Voltage [Vrms] Attack-Recovery Rb=8kΩ Ra=4kΩ 9pin Ir=0.5µA 11pin 12pin Cb Ca Smoothing circuit of Attenuate Smoothing circuit of Boost Attack and recovery time in the attenuation processing depends on external part Ca, and it in the boost processing depends on external part Cb. They become longer as the capacity bigger and become shorter as it gets smaller. (Recommendation value: Ca=1µF, Cb=4.7µF) Reducing the capacity of Ca may cause the distortion. As for Cb, since it serves as the click noise prevention, reducing the capacity may cause the click noise upon volume changing. - 10 - NJW1160 2. Tone Control a) Bass: Setting the Cut-off frequency Bass Filter 12k fC = 12k 8pin 23pin M 2π × C ×12k M changes by gain setting of Tone. M ≈ 2.65 M ≈ 3.45 M ≈ 8.10 C (±15dB) (±10dB) (±5dB) b) Treble: Setting the Cut-off frequency Treble Filter fC = N 2π × C ×10k N changes by gain setting of Tone. 10k C 3. 7pin 24pin N ≈ 0.76 N ≈ 0.58 N ≈ 0.25 (±15dB) (±10dB) (±5dB) BBE, Surround mode and "OUT" switch settings The click noise may be generated by changing the BBE, Surround mode setting and “OUT” switch. Provide the external circuit for avoiding the click noise on above condition. 4. External parts for BBE circuits The constant of capacitors connected to the terminals No.2, 3, 28 and 29 are designated by BBE Sound Inc. Do not change the constant of these capacitors without the approval of BBE Sound Inc. 5. AUX1, AUX0 Terminal AUX1/0 are enable to control external logic circuit is Source current : 1mA typ. (Ta=25˚C) Sink current : 0.5mA typ. (Ta=25˚C) 6. Capacitor for Reference Voltage (21pin) 22µF should be recommended for ripple filter connected to Vref terminal (21pin). Reducing this capacity may cause to reduce the maximum attenuation level and to increase the output noise. - 11 - NJW1160 2 ■ DEFINITION OF I C REGISTER 2 ♦I C BUS FORMAT MSB S LSB Slave Address 1bit 8bit MSB LSB A Select Address 1bit 8bit MSB A 1bit LSB Data A P 8bit 1bit 1bit S: Starting Term A: Acknowledge Bit P: Ending Term ♦ SLAVE ADDRESS MSB LSB 1 0 0 0 0 0 1 R/W R/W=0: Receive Only R/W=1: No Output Data ♦ CONTROL REGISTER TABLE The select address sets each function (Volume, Balance, AGC, Surround, Tone Control, BBE, AUX).
