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
• When RX1 is selected and the input signal to RX1 is always fixed to either "H" or "L" (Toslink etc), RX0 and RX2
• RX0, RX2, RX3, RX4, RX5, and RX6 are TTL input level compatible S/PDIF input pins with 5V-tolerance voltage.
