Serial Port Data Output.
Serial port control data output.
Serial Port Data Input.
Serial port control data input.
Chip Select Input.
An active low input control signal that enables the SPI Serial port. When
inactive, SCLK and SDI are ignored and SDO is high impedance.
Frame Sync Input.
Data framing signal that is used to indicate the start and stop of a
communication/data frame.
Master Clock Input.
Master clock input.
Transmit PCM or GCI Highway Data Output.
Outputs data from either the PCM or GCI highway bus.
Receive PCM or GCI Highway Data Input.
Receives data from either the PCM or GCI highway bus.
Ring Detect Output.
Produces an active low rectified version of the ring signal.
Analog Speaker Output/Interrupt Output.
Provides an analog output signal for driving a call progress speaker in AOUT
mode. Alternatively, this pin can be set to provide a hardware interrupt signal.
Ring Ground Output.
Control signal for ring ground relay. Used to support ground start applications.
No connect.
No connect.
TIP Ground Detect Input.
Used to detect current flowing in TIP for supporting ground start applications.
TIP Ground Detect Enable Output.
Control signal for the ground detect relay. Used to support ground start appli-
cations.
Reset Input.
An active low input that is used to reset all control registers to a defined,
initialized state. Also used to bring the Si3050 out of sleep mode.
