V+ (Pin 1): Voltage Supply (2.7V V+ 5.5V). This supply  
must be kept free from noise and ripple. It should be  
bypasseddirectlytotheGND(Pin2)witha0.1µFcapacitor

of N in the frequency equation. Pin 4 should be tied to V+  
forthe÷1setting,thehighestfrequencyrange.FloatingPin  
4 divides the master oscillator by 2. Pin 4 should be tied to  
GNDforthe÷4setting,thelowestfrequencyrange.Todetect  
a floating DIV pin, the LTC6905 attempts to pull the pin  
towardmidsupply.Thisisrealizedwithtwointernalcurrent  
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-  
quiressourcingapproximately15µA.Likewise,drivingDIV  
low requires sinking 15µA. 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.  
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.  
OUT (Pin 5): Oscillator Output. This pin can drive 5kΩ
