Function
Ground for Digital Section.
Analog-to-Digital Converter Input. The internal 7-bit ADC can be accessed through this pin. Full scale is 0 to
1.9 V. Readback is made using the SREAD pin.
Regulator Voltage for Digital Block. A 100 nF capacitor should be placed between this pin and ground for
regulator stability and noise rejection.
Voltage Supply for Digital Block. A decoupling capacitor (X7R or Tantalum) of 0.01 μF should be placed as
close as possible to this pin.
Bidirectional Pin. In output mode (INTerrupt mode), the ADF7020 asserts the INT/ LOCK pin when it has found
a match for the preamble sequence.
In input mode (lock mode), the microcontroller can be used to lock the demodulator threshold when a valid
preamble has been detected. Once the threshold is locked, NRZ data can be reliably received. In this mode, a
demod lock can be asserted with minimum delay.
Transmit Data Input/Received Data Output. This is a digital pin and normal CMOS levels apply.
In receive mode, the pin outputs the synchronized data clock. The positive clock edge is matched to the
center of the received data.
In GFSK transmit mode, the pin outputs an accurate clock to latch the data from the microcontroller into the
transmit section at the exact required data rate. See the Gaussian Frequency Shift Keying (GFSK) section.
A Divided-Down Version of the Crystal Reference with Output Driver. The digital clock output can be used to
drive several other CMOS inputs such as a microcontroller clock. The output has a 50:50 mark-space ratio.
This pin provides the Lock_Detect signal, which is used to determine if the PLL is locked to the correct
frequency. Other signals include Regulator_Ready, which is an indicator of the status of the serial interface
regulator.
The reference crystal should be connected between this pin and OSC1. A TCXO reference can be used by
driving this pin with CMOS levels and disabling the crystal oscillator.
The reference crystal should be connected between this pin and OSC2.
Voltage Supply for the Charge Pump and PLL Dividers. This pin should be decoupled to ground with a
0.01 μF capacitor.
Regulator Voltage for Charge Pump and PLL Dividers. A 100 nF capacitor should be placed between this pin
and ground for regulator stability and noise rejection.
Charge Pump Output. This output generates current pulses that are integrated in the loop filter. The
integrated current changes the control voltage on the input to the VCO.
Voltage Supply for VCO Tank Circuit. This pin should be decoupled to ground with a 0.01 μF capacitor.
Grounds for VCO Block.
A 22 nF capacitor should be placed between this pin and VREG1 to reduce VCO noise.
