OPS1-0: Output Through Data Select (Table 12)
Default: “00”, RX1
IPS1-0: Input Recovery Data Select (Table 11)
Default: “00”, RX1
LOOP1-0: Loopback mode enable
00: Normal (No loop back)
01: LIN → LOUT1, LOUT2, LOUT3, LOUT4
RIN → ROUT1, ROUT2, ROUT3, ROUT4
The ADC digital output (RX data in the PLL mode) is connected to the digital DAC input. In this
mode, the input DAC data to SDTI1-3 is ignored.
10: SDTI1(L) → SDTI2(L), SDTI3(L)
SDTI1(R) → SDTI2(R), SDTI3(R)
In this mode the input DAC data to SDTI2-3 is ignored.
11: N/A
LOOP1-0 should be set to “00” at TDM bit “1”.
