Features
* Built-in buffer amplifiers reduce the number of external components required. * Fabricated in a silicon gate CMOS process for minimal switching noise from built-in switches and minimal switching noise even when there is no input signal. * Built-in zero cross circuits minimize switching noise when input signals are present. * Built-in VDD/2 reference voltage generator circuit. * All functions are controlled from serial data. Supports the CCB bus.
* CCB is a trademark of SANYO ELECTRIC CO., LTD. * CCB is SANYO's original bus format and all the bus addresses are controlled by SANYO.

LC75348, 75348M Usage Notes * The internal transistor states are undefined when power is first applied. Applications must mute the output until control data has been written to the IC. * Operational description of the zero cross switching circuit The LC75348 and LC75348M provide a function that can switch the zero cross comparator signal detection point, allowing applications to select an optimal detection point for the block whose data is being updated. Basically, switching noise can be minimized if the signal immediately following the block whose data is updated is input to the zero cross comparator. This means that the detection point must be switched each time data is updated.

* Zero cross switching control procedure The zero cross switching control procedure consists of three steps. First, set the zero cross control bit to zero cross detection mode (D25 = 0), then specify the block for detection (with bits D28 and D29), and finally transfer the data. Since these control bits are latched first, immediately after the data is transferred, i.e. on the CE falling edge, the mode can be set in a single data transfer operation when updating the volume control or other control block data. The figure below presents an example of the control used when updating the volume control block data.

LC75348, 75348M * Zero cross timer setting If the input signal is lower than the zero cross comparator detection sensitivity, or if a low-frequency signal is input, the state in which the circuit cannot detect a zero cross may continue and the input data will not be latched during that period. The zero cross timer sets a time for the data to be latched forcibly in states such as this where a zero cross cannot be detected. For example, to set a 25 ms time: T = 0.69 CR Assume C = 0.068 F. The R will be: 25 x 10-3 R = ------------------ 530 k 0.69 x 0.068 x 10-6 Normally, a time in the range 10 to 50 ms is used. * Notes on serial data transfer (1) Cover the CL, DI, and CE signal lines with the ground pattern or use shielded lines to prevent the high-frequency digital signals carried by these lines from entering the analog signal system. (2) The LC75348 and LC75348M data format consists of 8 bits of address and 32 bits of data. When transmitting data as an even multiple of 8 bits (when transferring 36 bits of data), use the data format shown below. LC75348 and LC75348M Data Reception in Multiples of 8 Bits
