1 LV3319PM Application Note Electronic Volume IC with tone Control Overview The LV3319PM is an electronic volume and tone control IC implements a rich set of audio control functions with a minimal number of external components. Functions include input selection switching function, an input gain, volume, loudness, balance, fader, general-purpose ports and bass/mid/treble control. Functions Input switching: Single-end inputs(3 input systems) Single-end inputs(2 input systems) or differential inputs(1 input system) Differential inputs.(1 input system) Input gain control: The input single can be amplified by 0 to +18dB (1dB steps.) Loudness control: Taps are output starting at the 32dB position of the ladder resistor and a loudness function implemented with external capacitor and resistor components. Volume control: A total of 91 positions from +10 to 79dB in 1dB steps and db. 3 band equalizer control Bass control: The bass control gain can be maximum boost +20dB position and maximum cut 20dB position.(+20db to 20dB in 1dB steps.) The bass control center frequency 60Hz/70Hz/100Hz/120Hz can be selected. The bass control quality factor 1.0/2.0 can be selected. Middle control: The middle control gain can be maximum boost +20dB position and maximum cut 20dB position.(+20db to 20dB in 1dB steps.) The middle control center frequency 700Hz/1KHz/1.2KHz can be selected. The middle control quality factor 1.0/2.0 can be selected. Treble control: The treble control gain can be maximum boost +20dB position and maximum cut 20dB position.(+20db to 20dB in 1dB steps.) The treble control center frequency 7KHz/10KHz/11KHz/12KHz can be selected. The treble control quality factor 1.0/2.0 can be selected. Fader control: A total of 81 positions from 0 to 79dB in 1dB steps and db. Fader-front output (Fader-output block/general purpose output block selection.) General purpose ports control: Mono/stereo selection. A total of 81 positions from 0 to 79dB in 1dB steps and db. Input switching control block /general purpose input block selection.

25 Usage Cautions (1)Data Transmission at power on The status of internal analog switches is unstable at power on.therefore,perform muting or some other countermeasure until the data has been set. At power on,initial setting data must be sent once in order to stabilize the bias of each block in a short time. (2) Description of zero cross switching circuit operation The LV3319PM have a function to switch zero cross comparator signal detection locations,enabling the selection of the optimum detection location for blocks whose data is to be updated.basically,the switching noise can be minimized by inputting the signal immediately following the block whose data is to be updated to the zero cross comparator,so it is necessary to switch the detection location every time. Input gain Volume Fader Switch Zero cross comparator LV3319PM zero cross detection circuit (3) Zero Cross Switching Control method The zero cross switching control method consists of setting the zero cross control bits to the zero cross detection mode, and specifying the detection blocks before transmitting the data.these control bits are latched immediately following data transfer,so when updating data of volumes,etc.,it is possible to perform mode setting and zero cross switching with one data transfer. (4) Zero cross timer setting If the input signal becomes lower than the zero cross comparator detection sensitivity,or if only low-frequency signals are input,zero cross detection continues to be impossible,and data is not latched during this time.the zero cross timer can set a time for forcible latch during such a status when zero cross detection is not possible. 25/33

26 (5)Soft step operation The LV3319PM have a soft step function at volume block for low switching noise. The Soft step time can be selected by send to I2C control.(l0ms,20ms,40ms,80ms) Data latch timing soft step start soft step time (6)Soft mute operation The LV3319PM have a soft mute function for low switching noise, when this mute function set operation. (mute/unmute function select) The Soft mute time can be selected by send to I2C control.(0.6ms,5ms,40ms,80ms) A soft mute function can be implemented by set to soft mute on.(set to mute on/off) Soft mute time Soft mute time 26/33
