Data hold time : tHD:DAT Please hold the Data Hold Time (tHD:DAT) to 300ns or more to avoid status of unstable at SCL falling edge. The SDA block in the NJW1192 does not hold data. Add external data-delay-circuit of the SDA terminal, in case of not providing a hold time of at least 300nsec for the SDA in the master device. The time-consists of the data-delay-circuit of the SDA terminal are as follows. TLH ≈ RP*CD THL ≈ RD*CD (a) Low level Æ High level : (b) High level Æ Low level : In addition, Schottky barrier diode (SBD) influences a Low level at the Acknowledge. Therefore choose the low forward voltage (Vf) as much as possible.

Take care that the reduced C1 makes sensitive to ripple of power supply. The input impedance is designed about 48k ohms. The ground line should be inserted between each input lines to avoid cross talk. The wiring patern between these terminals and capacitors should be shortened to prevend the generating of wiring resistance. C5, C21 affect pop-noise when “VOL1” or “Tone Bass” are immediately controlled after powered. Though reducing the capacity of C5, C21may reduce pop-noise, it affects bass frequency characteristic on volume1 attenuation (See Page.22 Voltage Gain vs. Frequency characteristics). Use Pre Charge function for reducing pop-noise.(See Page.14) 6,27 Volume DC cut capacitor terminals 7,8,25,26 Loudness filter Taps Loudness frequency can be adjusted with external parts (See Page.7). Especialy, 8 and 25 pins should be kept from large signal lines such as digital signal lines or the other sound signal lines to avoid the digitaly noise or cross talk in Loudness mode. 9,10,11,22 Tone filter ,23,24 terminals 12,21 Tone outputs Balance Fader 13,20 volume inputs 14,15,18, Balance Fader 19 volume outputs Tone Bass and Treble cut off frequencycan be adjusted with external parts (See Page.7). These pins should be kept from large signal lines such as digital signal lines or the other sound signal lines to avoid the digitaly noise or cross talk in Loudness mode. Output impedance is designed about 50 ohms. Input impedance is designed about 24k ohms. Output impedance is designed about 50 ohms. These terminals should be inserted resistance about 100 ohms between terminal and signal sources to reduce the digitaly noise. 16,17 I2C control signal These lines should be kept from analog signal lines and or near by the chip to avoid digitaly noises. Inserted ground line between ports analog line and digital line should be recommended. –7– NJW1192 APPLICATION NOTES < Loudness fc adjustment > Loudness High and Low Boost cut off frequencies are able to adjust with the external parts as shown in fig.A.
