• Parallel Control Mode (SPB pin = “L”).
•Synchronous Mode (INAS pin = “L”).
• OMCLK/XTI Input =
• Input PORT: Slave mode, IBICK1 lock mode (64FSI), 24 bit MSB justified
• Output PORT: Slave mode, 24 bit MSB justified
• Dither = OFF, DEM=OFF, PM2/1 pin= “H/L” (6ch original mode)
C1= 0.1μF
C2=10μF
C3=1μF± 30%
Notes:
- All digital input pins should be not left floating.
- VSS1 -5 must be connected to the same ground plane.
- Connect a 1μF (± 30%; including temperature characteristics) capacitor between the VD18 pin and DVSS. When
- Refer to
DSP1
this capacitor is polarized, the positive polarity pin should be connected to the VD18 pin.
