Test Conditions
This value is important for crystal
oscillator start-up
Time between ENABLE of the IC with
FSK = H and activation of the CLK
output. The CLK is activated
synchronously to the output frequency
if the current through the XTAL has
reached 35% to 80% of its maximum
amplitude. Crystal parameters:
