+
(Pin 1):
Voltage Supply (2.7V
≤
V
+
≤
5.5V). This supply
must be kept free from noise and ripple. It should be
bypassed directly to the GND (Pin 2) with a 0.1
μ
F capacitor
or higher.
GND (Pin 2):
Ground. Should be tied to a ground plane for
best performance.
SET (Pin 3):
Frequency-Setting Resistor Input. The value
of the resistor connected between this pin and V
+
deter-
mines the oscillator frequency. The voltage on this pin is
held by the LTC6905 to approximately 1V below the V
+
voltage. For best performance, use a precision metal film
resistor with a value between 10k and 25k and limit the
capacitance on this pin to less than 10pF.
DIV (Pin 4):
Divider-Setting Input. This three-state input
selects among three divider settings, determining the value
of N in the frequency equation. Pin 4 should be tied to V
+
for the
÷
1 setting, the highest frequency range. Floating Pin
4 divides the master oscillator by 2. Pin 4 should be tied to
GND for the
÷
4 setting, the lowest frequency range. To detect
a floating DIV pin, the LTC6905 attempts to pull the pin
toward midsupply. This is realized with two internal current
sources, one tied to V
+
and Pin 4 and the other one tied to
ground and Pin 4. Therefore, driving the DIV pin high re-
quires sourcing approximately 15
μ
A. Likewise, driving DIV
low requires sinking 15
μ
A. When Pin 4 is floated, it should
be bypassed by a 1nF capacitor to ground or it should be
surrounded by a ground shield to prevent excessive cou-
pling from other PCB traces.
OUT (Pin 5):
Oscillator Output. This pin can drive 5k
and/or 5pF loads. For larger loads, refer to the Applications
Information section.
