LV3328PM overview the LV3328PM is an electronic volume and tone 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. features ? it is possible to eliminate from the external components of equalizer control block by scf technology. ? zero-cross switching circuits (volume control block , fader control block and general purpose volume block), soft step (3 band equalizer control) and soft mute circuits us ed for low noise even when input signals are present. ? low power consumption due to the use of bicmos process. functions ? input switching : single-end inputs (3 input systems). single-end inputs (2 input systems) or differential input (1 input system). differential input (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 : +10db to -79db/- (1db steps) l/r independent 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. continued on next page. bi-cmos lsi for car audio systems electronic volume ic orderin g numbe r : ena1657

LV3328PM no.a1657-23/26 usage cautions (1) request to send the initial data at power on ? though the circuit initializing the ic inside at power on is in corporated, be sure to send data to all sub-address as the initial data at power on. ? at power on, muting or other measures must be taken externally till the data is set. reference data parameter symbol conditions min typ max unit vdd power rise time trise 0v (2) description of zero cros s switching circuit operation the LV3328PM 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 sw itch the detection location every time. LV3328PM zero cross detection circuit (3) zero cross switching control method the zero cross switching control method c onsists of setting the zero cross control bits to the zero cross detection mode, and specifying the detection blocks before transmitting the data. the i 2 c data is held at rise of the ack clock. for zero-cross operation, this operation begins at rise of ack clock of the first data. on detecting zero cross, all of holding data are switched. (without zero cross, data is switched at rise of ack clock.) (4) zero cross timer setting if the input signal becomes lower than the zero cross co mparator detection sensitivity, or if only low-frequency signals are input, zero cross detection continues to be impo ssible, 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 LV3328PM have a soft step function at 3 band equalizer control block for low switching noise. the soft step time can be selected by send to i 2 c control. (l0ms, 20ms, 40ms, 80ms) input gain zero cross comparator switch volume fader soft step time data latch timing soft step start
LV3328PM no.a1657-24/26 (6) soft mute operation the LV3328PM 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 i 2 c control. (0.6ms, 5ms, 40ms, 80ms) a soft mute function can be implemented by set to soft mute on. (set to mute on/off) (7) cautions for input switching (method to reduce the switching noise at a time of channel setting) when switching the input channel, carry out soft muting beforehand. after completion of muting, carry out channel switching. then, cancel muting (canceling through soft mutin g ), and complete input switching (recommendation by sanyo). note also that, regardless of whether each input channel is set to on or off, the external input voltage is less than the maximum input voltage (vcl) in all input channels. soft mute time soft mute time
