System Modes and Initialization
Start-up and Initialization
After supply voltage is applied to the MICRF507, a power
on reset period elapses during which it should be
considered to be in an unknown state. The microcontroller
should wait until power on reset is completed. See
“Power-On Reset” subsection within the “Control (3-wire)
Interface” section. After power-on is completed, all 22
writeable registers must be correctly initialized before
operation of the MICRF507. Write only non-zero values to
the M0, N0, M1, and N1 fields.
MICRF507
When using VCO modulation; after MICRF507 has been
put in transmit mode, the microcontroller will tri-state the
driver connected to DATAIXO pin to leave that pin floating
until the microcontroller begins sending data. This is
because in transmit mode, the modulator is disabled while
the DATAIXO pin is floating (a weak voltage divider sets its
level at Vdd/2) in order to prevent a performance-
degrading transient when message transmission begins.
Below, “write to registers” means writing a complete
control word, or writing just to registers that need to
change.

mode, the MICRF507 needs to go through the standby
mode first. This is to ensure that the crystal oscillator starts
up correctly. Once the crystal oscillator settles, the
MICRF507 can go to receive or transmit mode.
When the mode has been changed to Transmit or
Receive, or when the power amplifier has been enabled,
the synthesizer must be allowed to stabilize. See “Lock
Detect” section.
