Description
Serial Data Daisy Chain.
Enables multiple devices to use a single CS for serial port con-
trol. Connect SDITHRU pin from master device to SDI pin of
slave device. An internal pullup resistor holds this pin high dur-
ing idle periods.
Chip Select.
Active low. When inactive, SCLK and SDI are ignored, and
SDO is high impedance. When active, serial port is operational.
Senses ring-trip condition when using centralized ring genera-
tor. Connect to high side of ring sense resistor. Shared by
channels a and b.
Exposed Die Paddle Ground.
Connect to a low-impedance ground plane via top side PCB
pad directly under the part. See Package Outlines: 64-Pin
TQFP for PCB pad dimensions.
Ring Generator Sensing Input.
