Provides support for parallel resonant AT cut crystals. A 4.9152 MHz crystal or a 4.9152 or 27 MHz
clock on XTALI is required.
XTALO—Crystal Oscillator Pin.
Serves as the output of the crystal amplifier.
Ring Indicator.
The RI on (active low) indicates the presence of an ON segment of a ring signal on the tele-
phone line.
Supply Voltage.
Provides the 3.3 V supply voltage to the Si2457/34/15/04.
Receive Data.
Data output to DTE RXD pin.
Transmit Data.
Data input from DTE TXD pin.
Clear to Send.
Signals that the Si2457/34/15/04 is ready to receive more digital data on the TXD pin.
Reset Input.
An active low input that is used to reset all control registers to a defined, initialized
state.
Isolation Capacitor 2A.
Connects to one side of the isolation capacitor C2.
Isolation Capacitor 1A.
Connects to one side of the isolation capacitor C1.
Interrupt Output.
Active low interrupt output.
Ground.
Connects to the system digital ground.
Regulator Voltage Reference.
Connects to an external capacitor and serves as the reference for the internal
voltage regulator.
Escape.
A positive edge on this pin causes the modem to go from online (connected) mode to
the offline (command) mode.
Carrier Detect.
Active low carrier detect.
Request to Send.
Active low request to send input used for flow control.
