Description
Output of the on-chip Xtal oscillator inverter.
Input to the on-chip Xtal oscillator inverter.
A logic level input for setting the mode of the device. See
section 4.2
A logic level input for setting the mode of the device. See
section 4.2
Input to the Rx input amplifier.
Output of the Rx input amplifier
Output of the FSK generator.
Negative supply (ground).
Internally generated bias voltage, held at VDD/2 when the
device is not in 'Zero-Power' mode. Should be bypassed to
VSS by a capacitor mounted close to the device pins.
A logic level input for enabling/disabling the equalizer in the
receive filter. See section 4.4
A logic level input for either the raw input to the FSK
Modulator or data to be re-timed depending on the state of
the M0, M1 and CLK inputs. See section 4.9
A logic level input which may be used to clock data bits in or
out of the FSK Data Retiming block.
A logic level output carrying either the raw output of the FSK
Demodulator or re-timed characters depending on the state of
the M0, M1 and CLK inputs. See section 4.8
A logic level output of the on-chip Energy Detect circuit.
"Ready for data transfer" output of the on-chip data retiming
circuit. This open-drain active low output 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 VDD.
Positive supply. Levels and thresholds within the device are
proportional to this voltage. Should be bypassed to VSS by a
capacitor mounted close to the device pins.
No internal connection
