NJ88C50

Fig.8 shows a typical application, using the NJ88C50 to

generate both VHF and UHF signals. External components

are kept to a minimum, requiring only bias, loop filter and

decoupling components. In many applications the UHF VCO

is a pre-assembled and tested module to suit the end equip-

ment use, whereas the VHF design is likely to be discrete. The

circuit shown is suitable for operation up to 1.1GHz and uses

a low power prescaler, the SP8715, feeding the NJ88C50 in

single ended mode. This requires a biasing network around

the differential input of the NJ88C50 to be used (pins 2 and 3).

Power supply and ground rails must have adequate

decoupling otherwise overall performance may be impaired.
