• Peak-to-peak (clock edge to clock edge)
• Long term (averaged over 2 ms interval)
In external clock mode, it is possible to run the chip directly from an external clock source without enabling the PLL.
This value has been updated.
All internal registers retain data at 0 Hz.
Depending on packaging; see the orderable part number summary.
Loss of Reference Frequency is the reference frequency detected internally, which transitions the PLL into self clocked mode.
Self clocked mode frequency is the frequency at which the PLL operates when the reference frequency falls below f
default MFD/RFD settings.
This parameter is characterized before qualification rather than 100% tested.
Proper PC board layout procedures must be followed to achieve specifications.
This specification applies to the period required for the PLL to relock after changing the MFD frequency control bits in the
synthesizer control register (SYNCR).
Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise
injected into the PLL circuitry via V
for a given interval.
