LV3319PM
Bi-CMOS LSI
Electronic Volume IC
for Car Audio Systems
http://onsemi.com
Overview
The LV3319PM 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 used 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.

 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.
Independent control each four channels output
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.

Usage Cautions
(1) Request to send the initial data at power ON
 Though the circuit initializing the IC inside at power ON is incorporated, 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.

(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.

(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.
The I2C 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 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 LV3319PM 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 I2C control. (l0ms, 20ms, 40ms, 80ms)

(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)

(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 muting ), and complete input switching (recommendation by
Our).
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.
