* Compatible with MSB justified 24 bits / LSB justified 24,20 and 16 bits
(Internal pull-down )
* Compatible with MSB justified 24 bits / LSB justified 24,20 and 16 bits
* It can change its function as a conditional jump pin JX0 by control register
setting (JX0_E).
Slave mode (SMODE=”L”) : Input the fs clock.
Master mode (SMODE=”H”): Connect to DVSS.
Slave mode: Input 64 fs or 48 fs clocks.
When it uses only for master mode then connect to DVSS. (SMODE=”H”)
SMODE=”L”: Slave mode.
SMODE=”H”: Master mode.
Master mode (SMODE=”H”) : Outputs 64fs clock.
Slave mode (SMODE=”L” ) : Outputs BITCLK_I clock.
Master mode (SMODE=”H”) : Outputs the fs clock.
Slave mode (SMODE=”L”) : Outputs LRCLK_I clock.
Output frequency can be selectable by control register.
When crystal oscillator is used, it should be connected to this pin and XTI.
When the external clock is used, keep this pin open.
Connect a crystal oscillator between this pin and the XTO pin,
Or input the external CMOS clock signal to XTI pin.
