2 AUDIO PROCCESOR with SRS&BBE& GENERAL DESCRIPTION NJW1177 is a sound processor includes all of the functions required to process the audio signal for TV, such as volume, balance, mute, tone control, AGCfunctions. And also It performs NJRC original dynamic bass boost technology provides graceful bass sound with low distortion. All of internal states and variables are controlled by I 2 C BUS interface. In addition to SRS and BBE, since NJW1177 builds in, it reproduces clearly, natural and rich bass sound PACKAGE OUTLINE NJW1177V FEATURES Operating Voltage +7. to +13V I 2 C BUS interface BBE Sound Enhancement (Low Boost and High Boost: 1dB max.)

The SDA block in the NJW1177 does not hold data. Add external data-delay-circuit of the SDA terminal, in case of not providing a hold time of at least 3nsec for the SDA in the master device. The time-consists of the data-delay-circuit of the SDA terminal are as follows. (a) Low level! High level : (b) High level!
