Connect to CP with a 1.0μF capacitor that should have the low ESR
( Equivalent Series Resistance ) over all temperature range. When this
capacitor has the polarity, the positive polarity pin should be connected to the
CP pin. Non polarity capacitors can also be used.
Connect to CN with a 1.0μF capacitor that should have the low ESR
( Equivalent Series Resistance ) over all temperature range. When this
capacitor has the polarity, the positive polarity pin should be connected to the
CP pin. Non polarity capacitors can also be used.
Connect to VSS2 with a 1.0μF capacitor that should have the low ESR
( Equivalent Series Resistance ) over all temperature range. When this
capacitor has the polarity, the positive polarity pin should be connected to the
VSS2 pin. Non polarity capacitors can also be used.
“H”: Enable, “L”: Disable
An external TTL clock should be input on this pin.
“L”: Left Justified, “H”: I2S
When power down, outputs VSS(0V, typ).
When power down, outputs VSS(0V, typ).
