Switching port P0.
‘0’ = disabled (high impedance).
‘1’ = enabled.
Output which indicates that phase
comparator phase and frequency lock
has been obtained and that the varactor
voltage is within ‘tune unlock’ window.
This powers up in logic ‘0’ state.
+5 V voltage supply for RF
RF Bypass differential outputs.
AC couple outputs. Matching circuitry as
per applications diagram (Figure 2).
In applications where RF Bypass is not
required, pins should not be connected.
+5 V voltage supply for RF
Not connected. Ground externally.
RF differential inputs.
AC couple input.
Matching circuitry as per applications
diagram.
Not connected. Ground externally.
RF analogue gain control input
