Description
Connect to ground
Internal bandgap voltage (1.18V)
2V bias voltage for AC signals
Power fail alarm at VCC input. This pin is an open-drain output of negative
logic.
Power fail alarm at VDD input. This pin is an open-drain output of negative
logic.
Feedback (non-inverting) input for the shunt regulator
Divided voltage of VCC input. Feeding this voltage to SHSETIN pin results in
5V voltage at VCC.
Control pin of the shunt regulator. Its sink current (25mA max) is controlled
so that the voltage at SHSETIN is equal to V
The current absorbed by SHUNT pin (25mA max) is fed to this pin, which
must be connected to the ground level
Ground
Ground
Feedback (inverting) input for the series regulator. The series regulator
controls its output (SRAO) to make this input voltage is equal to VREF
(1.18V).
Divided voltage of VO output. Feeding this voltage into SRSETIN pin results
in 3V at VO pin.
Output pin of an operational amplifier for the series regulator
Gate of a PMOS transistor for the series regulator
Output pin of the series regulator (20mA max)
Supply voltage input for digital block
Analog supply voltage
Current integration to limit output slew rate
Ground
Output of an operational amplifier for slew rate control. This signal can be fed
to current driver.
Ground
Non-inverting input of an operational amplifier for transmission current driver
Inverting input of an operational amplifier for transmission current driver
Output of an operational amplifier for transmission current driver
For POL = VDD MDS_CTRL should = VSS
For POL = VSS MDS_CTRL can be tied to VDD or used as a not reset to
control when transmit communications will be enabled
Input pin of the band-pass filter. This pin is connected to VMID bias level with
270K resistor.
Feedback signal of high-pass filter. This pin is connected to the output of an
op-amp for high pass filter with 75K resistor.
Non-inverting input of an operational amplifier for the low-pass filter
Input pin of low-pass filter for feedback. This pin is connected to the output of
the high-pass filter through 20kΩ and the non-inverting input of the low-pass
filter through 54kΩ resisters.
Output of the operational amplifier for the low-pass filter.
internally connected to non-inverting input to form a voltage-follower.
Current integration (for carrier detect circuit)
