LV3313PM
No.A1257-17/18
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.
LV3313PM 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) 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)
