10.2.3 S/PDIF input circuits (RX0 to RX6)
• _{RX0, RX2, RX3, RX4, RX5, and RX6 can be received the data of 32kHz to 192kHz.}
• _{RX1 can be received up to 96kHz data.}
• _{If RX1 with a built-in amplifier is used as a coaxial input pin, malfunction may occur due to the influence from the}
adjacent RX0 and RX2 input pins. To avoid the influences from those pins, fix RX0 and RX2 to "L". In addition, the
pull-down resistor is inserted after the coupling capacitor for the noise measures, when the signal is not connected
with RX1 is selected.
• _{When RX1 is selected and the input signal to RX1 is always fixed to either "H" or "L" (Toslink etc), RX0 and RX2}
processes are not required.
• _{RX0, RX2, RX3, RX4, RX5, and RX6 are TTL input level compatible S/PDIF input pins with 5V-tolerance voltage.}
