Input 1 to Crosspoint C
High Side of Bias Network for Crosspoint C. Use to give the C outputs a DC bias when
inputs are AC-coupled (refer to the Using the Internal Bias Resistors section).
Input 2 to Crosspoint C
Shunt Input to Crosspoint C. Use for shunt capacitor of AC ground connection to improve
off-isolation, or as an additional input to switch matrix C.
Input 3 to Crosspoint C
Positive Supply Voltage. Supply range is 2.7V to 5.5V.
Input 1 to Crosspoint A
Input 1 to Crosspoint B
Shunt Input to Crosspoint A. Use for shunt capacitor of AC ground connection to improve
off-isolation, or as an additional input to switch matrix A.
Input 2 to Crosspoint A
Input 2 to Crosspoint B
Shunt Input to Crosspoint B. Use for shunt capacitor of AC ground connection to improve
off-isolation, or as an additional input to switch matrix B.
Input 3 to Crosspoint A
Input 3 to Crosspoint B
Ground
2-Wire Serial-Interface Data Input. Data is clocked in on SCL’s rising edge.
3-Wire Serial-Interface Data Input. Data is clocked in on SCLK’s rising edge.
2-Wire Serial-Interface Clock Input
3-Wire Serial-Interface Clock Input
LSB+1 of 2-Wire Serial-Interface Address Field
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.
LSB of 2-Wire Serial-Interface Address Field
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.
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).
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).
Audio Bypass for SA and SB Inputs
Output 2 of Crosspoint B
Crosspoint Switches
