APPLICATIONS INFORMATION
JITTER AND DIVIDE RATIO
At a given output frequency, a higher master oscillator
frequency and a higher divide ratio will result in lower
jitter and higher power supply dissipation. Indeterminate
jitter percentage will decrease by a factor of slightly less
than the square root of the divider ratio, while determinate
jitter will not be similarly attenuated. Please consult the
specication tables and Jitter vs Frequency graph showing
jitter at various divider ratios.
JITTER AND STRAY CAPACITANCE ON THE SET PIN
(PIN 3)
The stray capacitance on the SET pin (Pin 3) should be
limited to 10pF or less to avoid increased jitter or unstable
oscillation.
LTC6905 SUGGESTED CRITICAL COMPONENT LAYOUT
In order to provide the specied performance, it is re-
quired that the frequency setting resistor RSET and the
supply bypass capacitor be placed as close as possible
to the LTC6905. The following additional rules should be
followed for best performance:
1) The bypass capacitor must be placed as close as possible
to the LTC6905, and no vias should be placed between
the capacitor and the LTC6905. The bypass capacitor
must be on the same side of the circuit board as the
LTC6905.
2) The resistor RSET should be placed as close as possible
to the LTC6905, and the connection of RSET to VCC
should be closely shared with the bypass capacitor.
The resistor RSET may be placed on the opposite side
of the board from the LTC6905, directly underneath the
bypass capacitor.
3) If a ground plane is used, the connection of the LTC6905
to the ground plane should be as close as possible
to the LTC6905 GND pin and should be composed of
multiple, high current capacity vias.
