XTALI — Crystal Oscillator Pin.
These pins provide support for parallel resonant, AT cut crystals. XTALI also acts as
an input in the event that an external clock source is used in place of a crystal.
XTALO — Crystal Oscillator Pin.
Serves as the output of the crystal amplifier. A 4.9152 MHz crystal is required or a
4.9152 MHz clock on XTALI.
Clock Output.
This signal is typically used to clock an output system microcontroller. The frequency
is 78.6432 MHz/(N+1), where N is programmable from 0 to 31. N defaults to 7 on
power up. Setting N = 0 stops the clock.
Digital Supply Voltage.
Provides the digital supply voltage to the Si2400. Nominally either 5 V or 3.3 V.
Receive Data.
Serial communication data from the Si2400.
Transmit Data.
Serial communication data to the Si2400.
Clear to Send.
Clear to send output used by the Si2400 to signal that the device 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. Also used to bring the Si2400 out of sleep mode.
Analog Speaker Output.
Provides an analog output signal for monitoring call progress tones or to output voice
data to a speaker.
