| Ordering number : ENA0720A Bi-CMOS LSI LV3311PNM Overview For Car Audio Systems Electronic Volume IC The LV3311PNM is an electronic volume 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, bass/mid/treble and subwoofer control. Features * It is possible to eliminate from the external components of equalizer control block by SCF technology. * Zero-cross switching circuits (Volume control block and Fader control block), soft step (3 band equalizer control and Suboofer control) and soft mute circuits used for low noise even when input signals are present. * Low power consumption due to the use of BiCMOS process. * All functions are controlled using serial data (CCB). Features * Input selector : Four of the input systems are single-end inputs, one uses differential inputs. * 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 : +10dB to -79dB/- (1dB steps) L/R independent control.

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 LV3311PNM 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 LV3311PNM 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, that is to say beforehand in sync with the falling edge of CE, 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. (5) Soft step operation The LV3311PNM have a soft step function at 3 band equalizer block and subwoofer block for low switching noise. The Soft step time can be selected by send to CCB control. (l0ms, 20ms, 40ms, 80ms) A soft step function can be implemented by set to soft step on. (Set to minimum step) CE "H" "L" soft step start soft step time No.A0720-18/20 LV3311PNM (6) Soft mute operation The LV3311PNM 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 CCB 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 (7) The next set data must not be sent when zero cross operation is enabled or soft step/soft mute operation is performed.
