NAME
LSB of 2-Wire Serial-Interface Address Field
–
20
Chip Select of 3-Wire Serial Interface. Logic low on CS enables serial data to be clocked
in to device. Programming commands are executed on CS’s rising edge.
20
–
Low Side of Bias Network for Crosspoint A and B. Use to give the A and B outputs a DC
bias when inputs are AC-coupled (refer to the
Using the Internal Bias Resistors section).
22
High Side of Bias Network for Crosspoint A and B. Use to give the A and B outputs a DC
bias when inputs are AC-coupled (refer to the
Using the Internal Bias Resistors section).
23
Audio Bypass for SA and SB Inputs
24
2-Wire Serial-Interface Clock Input
–
18
3-Wire Serial-Interface Clock Input
18
–
LSB+1 of 2-Wire Serial-Interface Address Field
–
19
Data Output of 3-Wire Serial-Interface. Input data is clocked on SCLK’s falling edge
delayed by 24 clock cycles. DOUT remains active when CS is high.
19
–
3-Wire Serial-Interface Data Input. Data is clocked in on SCLK’s rising edge.
17
–
2-Wire Serial-Interface Data Input. Data is clocked in on SCL’s rising edge.
