All values given are initial design targets and subject to change.
All internal registers retain data at 0 Hz.
“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 that the PLL operates at when the reference frequency falls
below f
LOR
with default MFD/RFD settings.
This parameter is guaranteed by characterization 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).
Assuming a reference is available at power up, lock time is measured from the time V
DD
and V
DDSYN
are
valid to RSTOUT negating. If the crystal oscillator is being used as the reference for the PLL, then the
crystal start up time must be added to the PLL lock time to determine the total start-up time.

PLL is operating in 1:1 PLL mode.
11
Jitter is the average deviation from the programmed frequency measured over the specified interval at
maximum f
sys/2
. 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
DDSYN
and V
SSSYN
and variation in
crystal oscillator frequency increase the Cjitter percentage for a given interval.
12
Values are with frequency modulation disabled. If frequency modulation is enabled, jitter is the sum of
Cjitter+Cmod.
13
Modulation percentage applies over an interval of 10
μ
s, or equivalently the modulation rate is 100KHz.
14
Modulation rate selected must not result in f
sys/2
value greater than the f
sys/2
maximum specified value.
