Master Clock Input.
High speed master clock input. Generally supplied by the system crystal clock or
modem/DSP.
Frame Sync Output.
Data framing signal that indicates the start and stop of a communication/data frame.
Serial Port Bit Clock Output.
Controls the serial data on SDO and latches the data on SDI.
Digital Supply Voltage.
Provides the 3.3 V digital supply voltage to the Si3056.
Serial Port Data Out.
Serial communication data that is provided by the Si3056 to the modem/DSP.
Serial Port Data In.
Serial communication and control data that is generated by the modem/DSP and pre-
sented as an input to the Si3056.
Secondary Transfer Request Input/Ring Detect.
An optional signal to instruct the Si3056 that control data is being requested in a sec-
ondary frame. When daisy chain is enabled, this pin becomes the ring detect output.
Produces an active low rectified version of the ring signal.
Reset Input.
An active low input that resets all control registers to a defined, initialized state. Also
used to bring the Si3056 out of sleep mode.
Isolation Capacitor 2A.
Connects to one side of the isolation capacitor C2. Used to communicate with the line-
side device.
Isolation Capacitor 1A.
Connects to one side of the isolation capacitor C1. Used to communicate with the line-
side device.
