LV3329PE

Orderin Ordering number : ENA1856 Bi-CMOS LSI LV3329PE Overview For Car Audio Systems Electronic Volume IC The LV3329PE is an electronic volume and tone IC that implements a rich set of audio control functions with a minimal number of external components. Functions include input selection switching, an input gain, volume, loudness, balance, fader, bass/mid/treble control, and fixed equalizer. Features • It is possible to eliminate from the external components of equalizer control block by SCF technology. • Zero-cross switching circuits, soft steps (bass block and mid 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 controls performed using serial data input (CCB). Functions • Input selector : Four of the input systems are single-end inputs, one uses differential inputs. • Input gain control : The input gain can be amplified by 0 to +19dB (0 to 5dB/1.25dB steps, 5 to 11dB/1.5dB steps, 11 to 19dB/2dB 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 : 0dB to -79dB/-∞ (1dB steps) L/R independent control.

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 LV3329PE 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 LV3329PE zero cross detection circuit • Zero cross switching operates at the timing (rising edge and falling edge) when the signal crosses the reference voltage. (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. (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. The method of obtaining the timer time is shown below. Vs R1 TIM Vcrt Vcrt Tr Rt T Ct No.A1856-26/30 LV3329PE T = -Ct × (R1 + Rt) × 1n Vs - Vcrt • • • [1] Rt Vs × ( 1 - R1 + Rt ) Calculation example) • VDD = 8V, Vs = 4V • Vctr = 1.75V • R1 = 930kΩ (TIM pin internal resistance) • Ct = 0.022μF (External Ct) • Rt = 150kΩ (External Rt) The timer time “T” is obtained by formula [1] above. In this example, T = 10.1ms. (5) Bass/mid-range block soft step operation The LV3329PE has a soft step function at bass and mid-range blocks to minimize switching noise. The soft step time for the bass and mid-range blocks is 10ms or 20ms and can be selected using serial data. When set to soft step on, a soft step function for the bass or mid-range block can be implemented at the minimum resolution step intervals. CE "H" → "L" soft step start soft step time (6) Soft mute operation The LV3329PE 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 No.A1856-27/30 LV3329PE (7) Step mode operation In step mode, when the main volume is switched between 0dB and -32dB in 2-dB steps, the volume is first set to the midpoint level of before and after the setting, and then to the final value. The volume is set at the zero cross operation timing. (Condition: Set to zero cross mode.) This operation further reduces the switching noise, in addition to the effects of countermeasures against switching noise due to zero cross operation. (8) Notes during data control 1) Notes when transmitting data continuously (1) Transmit the initial data once at power ON. (REG0, D0 to D11 = ALL “0”) Set each register thereafter, but be sure to set REG7 (zero cross setting “ON”) last. (2) Do not transmit data during soft mute operation. Wait until soft step operation is finished before transmitting the data. (It is recommended to set the data transmission interval of approximately twice the soft mute setting time.) (3) Do not transmit data during soft step operation. Wait until soft step operation is finished before transmitting the data. (It is recommended to set the data transmission interval of approximately twice the soft step setting time.) (4) Do not transmit soft mute or soft step operation data during zero cross operation (when data is set while zero cross is set to “ON”). Wait until zero cross operation is finished before transmitting soft mute or soft step data. Set the data transmission interval to be equal or longer that the zero cross timer setting time. (Recommended interval: Zero cross timer setting time +10ms) (5) When performing BASS control or MID control in soft step mode, transmit data with the step level interval set to the minimum resolution possible. 2) Notes when setting the mode (1) When performing soft step control, always set REG12 (soft step setting time) and REG13 (soft step operation “ON”) before transmitting the BASS control and MID control step data. (The soft step setting time and soft step operation setting data are transmitted one time in the initial stage, and the soft step mode is maintained thereafter until the power is turned off or the soft step setting time or soft step operation setting is changed. Therefore, there is no need to repeatedly transmit the soft step setting time or soft step operation setting data.) (2) When performing zero cross control, always set REG7 (zero cross detection “ON,” zero cross detection block selection) before transmitting the input selection switching control, input gain control, main volume control, treble control and fader control step data. (The zero cross detection and zero cross detection block selection setting data are transmitted one time in the initial stage, and the zero cross detection mode is maintained thereafter until the power is turned off or the zero cross detection or zero cross detection block selection setting is changed. Therefore, there is no need to repeatedly transmit the zero cross detection or zero cross detection block selection setting data.)
