LC89075W-H SANYO [Sanyo Semicon Device], LC89075W-H Datasheet - Page 25

• Manufacturer Part Number: LC89075W-H
• Description: Digital Audio Interface Receiver with Stereo ADC and Audio Selector
• Manufacturer: SANYO [Sanyo Semicon Device]

• The PLL clock output frequencies are shown below.
• When “RXCKAT=1” and “RXMCK[1:0]=01” are set (512fs), 128kHz, 176.4kHz and 192kHz S/PDIF reception
*: Direct output to the MCKOUT pin is not guaranteed.
10.1.2 XIN Source Master Clock (XIN, XOUT, XMCK)
• The DIR uses clock supply to XIN for the following applications.
• A clock must always be supplied to XIN.
• Normally, the oscillation amplifier always operates regardless of the PLL status, but operation that automatically stops
• When “SW1SEL[2:0]=001”, “SW2SEL[2:0]=001” or slave mode “MPSEL[1:0] =10 or 11”, the oscillation amplifier
results in a PLL output frequency that exceeds 50MHz, so direct output to MCKOUT is not guaranteed.
the oscillation amplifier while the PLL is locked can also be set. This is set by the AMPOPR[1:0] register.
The AMPOPR[1:0] register must be set before S/PDIF input, or the setting must be completed while the PLL is
unlocked. In addition, when the oscillation amplifier is automatically stopped, the XMCK clock is not output.
is set to continuous operation mode. This has higher priority than the AMPOPR[1:0] register setting.
1) Clock source when the PLL is unlocked
2) PLL lock-in support
3) Calculation of the input data sampling frequency
