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

10.1.7 Output clocks (RMCK, RBCK, RLRCK, SBCK, SLRCK)
• The LC89058W-E features two clock systems (R and S systems) in order to supply the various needed clocks to
• The clock output settings for the R and S systems are done with PLLACC, PLLDV1, PLLVD2, PRSEL[1:0],
• Setting range for each clock output pin when the PLL is used as source
• Setting range for each clock output pins when the XIN is used as source
• The polarity of RMCK can be reversed with RMCKP.
• The polarity of RBCK, RLRCK, SBCK, and SLRCK can be reversed with RBCKP, RLRCKP, SBCKP, and SLRCKP.
Notes:
• RBCK and SBCK output clock must not quicken more than RMCK output clock frequency. Also, RBCK and SBCK
peripheral devices such as A/D converter and DSP.
XRSEL[1:0], XRBCK[1:0], XRLRCK[1:0], PSBCK[1:0], PSLRCK[1:0], XSBCK[1:0], and XSLRCK[1:0].
Output Pin Name
output clock are set to become 1/2 or less of RMCK output clock at XIN source. If it doesn’t follow these conditions,
RBCK and SBCK clocks are not output.
