YAC526
EVR3
Electric Variable Resistance 3
Outline
YAC526 (EVR3) is a 2ch high grade digital volume LSI for high-end audio systems.
Owing to its built-in high-quality sound operational amplifier, output with wide dynamic range and low distortion
www.DataSfhaecteotr4cUa.ncobme obtained.
YAC526 is able to control each channel through a serial data interface in 255 steps at 0.5dB per step, and
daisy chain connection can constitute a multichannel system.
Owing to its zero-cross detection function, the device is able to suppress audible noise that may occur at a quick
volume change.

Digital functions
Serial data interface
Writing of volume control data into YAC526 is performed through a serial interface. SDATAI is a serial data input
pin, SCLK is a clock input pin, and CSN is a chip select pin for writing the value of volume. 16-bit serial data that
is inputted from SDATAI (MSB first) is taken into YAC526 at the rising edge of SCLK when CSN terminal is at
"L" level. The serial data is latched at the rising edge of CSN, and volume value of each channel is set into the
register. The present volume value is outputted from SDATAO pin as serial data. With this data, the control by
using daisy chain connection and verification of the present volume value can be performed easily.
Note that the register value after turning the power supply on is ALL"0" (muted state) and the interface is
enabled after a predetermined period (tPUP) has elapsed. (Serial access is prohibited in tPUP period.)

Assignment of volume control data
D[15: 8] : Channel1 Volume data D1[15:0] is volume data value to change.
D[ 7: 0] : Channel2 Volume data D0[15:0] is present volume data value.
Daisy chain
YAC526 is extensible to a multichannel system with daisy chain connection.
For example, by connecting the device with YAC523 (7ch digital volume) through daisy chain, 8.1ch system can
be attained. By connecting SDATAO pin of YAC526 (or YAC523) to SDATAI pin of YAC523 (or YAC526),
YAC526 and YAC523 can be controlled simultaneously without need of a complex addressing.
(It is also possible to connect multiple YAC526.)
The volume data is taken into S/P (serial / parallel) registers of each LSI by setting CSN pin to "L" for 8 clock
period on all channels that are connected with daisy chain. And, by setting CSN pin to "H" after the elapse of 8
clock period on all channels, the data is written from S/P registers of all YAC526 (or YAC523) that are connected
with daisy chain into the control registers simultaneously to change the volume value.
Example: Assignment of volume control data when a combination of YAC526 and YAC523 as described below
is used.
