• Manufacturer Part Number: lc89058w
• Description: Cmos Digital Audio Interface Receiver
• Manufacturer: Sanyo Semiconductor Corporation

9.3 Master/Slave Settings (CKST)
• A master/slave function that allows multi-channel synchronized transfer using multiple LC89058W-Es is included.
• Set to the master mode normally, when single LC89058W-E IC is used. When multiple LC89058W-Es are used, set
• In the multi-channel synchronous transfer mode using multiple LC89058W-Es, connect RBCK and RLRCK (output)
• The master/slave function runs correctly with the multiple LC89058W-Es connected.
• Be sure to connect either a pull-down resistor or a pull-up resistor to CKST.
• Always supply the clock to RBCK and RLRCK when the slave function is set.
9.4 Pins 44 to 47 I/O settings ( INT )
• Pins 44 to 47 are provided with a bidirectional buffer.
• When setting I/O function of pins 44 to 47, connect a 10kΩ pull-down or pull-up resistor to INT .
• Be sure to connect either a pull-down resistor or a pull-up resistor to INT .
For this setting, connects either a 10kΩ pull-down or a pull-up resistor to CKST.
one of them to the master mode and the others to the slave mode.
on the master side to RBCK and RLRCK (input) on the slave side. Also connect XMCK on the master side to XIN on
the slave side. At this time, the polarity of RBCK and RLRCK, and the frequency of XIN and XMCK must be
identical.
