RF OUTPUT TRISTATE CONTROL
Parameter
Test Condition
Output enabled
Active high or open circuit ≥0.6 Vcc (100 kΩ internal pull up)
Output tristate mode
Tri-state control
In tri-state mode, the RF output stage is disabled but the
oscillator, compensation circuit and digital section are still active.
An RF enable signal to stable frequency operation is therefore
very rapid

LF TIMING PULSE: PULSE WIDTH
Parameter
Test Condition
LF pulse width
Ripple counter setting. User programmable register.
Divider ratio at power up: 64
LF pulse width
LF timing pulse width = oscillator period * ripple
