IRQN
Type
O/P
An open-drain active low output that may be
used as an Interrupt Request / Wake-up input to
the associated µC. An external pull-up resistor
should be connected between this output and
V
DD
.
A logic level output driven by the Ring or Line
Polarity Reversal Detector, the Tone Alert
Detector or the FSK Level detect circuits,
depending on the operating mode. See section
1.5.1.
An input which may be used to clock received
data bits out of the FSK Data Retiming block.
A logic level output carrying either the raw
output of the FSK Demodulator or re-timed 8-bit
characters depending on the state of the RXCK
input. See section 1.5.6
The positive supply rail. Levels and thresholds
within the device are proportional to this voltage.
Should be decoupled to VSS by a capacitor
mounted close to the device pins.
