), feedback resistor (R

S
) are incorporated internally when RANGE = HGO =
0.
5. This parameter is characterized and not tested on each device.
6. Proper PC board layout procedures must be followed to achieve specifications.
7. This specification applies to any time the FLL reference source or reference divider is changed, trim value changed,
DMX32 bit is changed, DRS bit is changed, or changing from FLL disabled (FBELP, FBILP) to FLL enabled (FEI, FEE,
FBE, FBI). If a crystal/resonator is being used as the reference, this specification assumes it is already running.
8. Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
Bus
.
Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise
injected into the FLL circuitry via V
DD
 and V
SS
 and variation in crystal oscillator frequency increase the C
Jitter
 percentage
for a given interval.
