9.0 System Power-Up Sequence
In order to correctly power-up the LMX9820 the following
sequence must be performed:
Apply IOVCC and VCC to the LMX9820.
The Reset_b# and Reset_5100# of the LMX9820 should
be driven high minimum of 2ms after the LMX9820 voltage
rails are high. The LMX9820 is properly reset.
Reference Table 24 on page 20.
