Typical Application Example
Operational Notes
TLW12458 – 22
VCO is assumed AC coupled
RIN increases impedance so that VCO output power is provided to the load rather than the PLL Typical values are 10X to 200X depending on the VCO power
level fIN RF impedance ranges from 40X to 100X
50X 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 OSCIN may be AC or DC coupled AC coupling is recommended because the input circuit provides its own bias (See Figure below)
TLW12458 – 23
Application Hints
Proper use of grounds and bypass capacitors is essential to achieve a high level of performance
Crosstalk between pins can be reduced by careful board layout
This is an electrostatic sensitive device It should be handled only at static free work stations
