... Line Input The Si4710/11 provides left and right channel line inputs (LIN and RIN). The inputs are high-impedance and low- capacitance, suited to receiving line level signals from external audio baseband processors. Both line inputs are low-noise inputs with programmable attenuation. Passive and active anti-aliasing filters are incorporated to prevent high frequencies from aliasing into the audio band and degrading performance ...

... SCLK. For read operations, the control word is followed by a delay of one-half SCLK cycle for bus turnaround. Next, the Si4710/11 drives the 16-bit read data word serially on SDIO, changing the state of SDIO on each rising edge of SCLK. A transaction ends when the user sets SEN high, then pulses SCLK high and low one final time ...
