LV3313PM
Bi-CMOS LSI
Electronic Volume IC
for Car Audio Systems
http://onsemi.com
Overview
The LV3313PM is an electronic volume IC that implements a rich set of audio control functions including input
selection switching function, an input gain, volume, loudness, balance, fader, and bass/treble control.
Features
 Zero-cross switching circuits (Input gain control block and Volume control block) can switch signal detection
location automatically.
 Zero-cross switching circuits (Input gain control block and Volume control block) and soft mute circuits used for low
noise even when input signals are present.
 Low power consumption due to the use of BiMOS process.
 All functions are controlled using serial data (CCB).
Functions
 Input selector :
Four input signals can be selected (three single-ended inputs and one differential input).
 Input gain control :
The input signal can be amplified by 0dB 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 : +12dB to -12dB in 2dB steps
 Treble control : +12dB to -12dB in 2dB steps
 Fader control :
The fader volume can be attenuations by one of 16 levels. Independent control each four channels. (A total of 16
settings with attenuations of 0dB to -2dB in 1dB steps, -2dB to -20dB in 2dB steps, and -30dB, -45dB, - 60dB and
-dB settings.)

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 LV3313PM 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. 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) Soft mute operation
The LV3313PM 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)
