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
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).

–
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.
