1.0 Functional Description
(Continued)
1.6 Typical Application Example
DS100127-11
OPERATIONAL NOTES:
*
VCO is assumed AC coupled.
**
R1 increases impedance so that VCO output power is provided to the load rather than the PLL. Typical values are 10
to 200
depending on the VCO
power level. f
IN
RF impedance ranges from 40
to 100
.
**
50
termination is often used on test boards to allow use of external reference oscillator. For most typical products a CMOS clock is used and no terminating
resistor is required. OSC
IN
may be AC or DC coupled. AC coupling is recommended because the input circuit provides its own bias. (See Figure below.)
