Setting Functions

1.4.2Detailed Explanation of Function Setting Switches and Header Pins

SW001: Switch to select S/PDIF input connector (optical/coaxial). Selection of the S/PDIF signal that is routed to the DIR1703 DIN port.

SW002: Reset switch for the DIR1703 and DIT4096. Pushing this switch resets the DIR1703 and DIT4096 to the initial state. A reset circuit operates at the time of power-supply connection, resetting the DIR1703 and DIT4096 automatically. Therefore, it is not usually necessary to operate this switch.

SW003: Switch for setting the DIR1703 system clock and output data format

SCF1	SCF0	System Clock
L	L	128 fS
L	H	256 fS (initial stting)
H	L	384 fS
H	H	512 fS

FMT1	FMT0	Output Data Format
L	L	16-bit right-justified, MSB-first
L	H	24-bit right-justified, MSB-first
H	L	24-bit left-justified, MSB-first
H	H	24-bit, I2S (initial setting)

SW004: Switch for setting the DIR1703 output clock source

Position		Output Clock (SCK, BCK, LRCK)
X’tal		Crystal clock
PLL		PLL clock
Auto		PLL (PLL locked) / crystal (PLL unlocked)
Note:	When using the DIR1703 as a master clock for the ADC, this switch must be set to X’tal.
	When inputting S/PDIF data demodulated by the DIR1703 into the DAC, set this switch to Auto or PLL.

SW005: Switch for setting the DIT4096 system clock and input data format Note that the OFF state of this switch sets a HIGH level.

CLK1	CLK0	System Clock
L	L	Not used
L	H	256 fS (initial setting)
H	L	384 fS
H	H	512 fS
