Please page two, Figure inset. inset Figure from single supply must install resistor connect jumper switches between pins each jumper switch headers. This your evaluation board comes from factory. Connections available board from separate supply sources desired. must from separate sources must change jumper switch positions also have remove component RSP. minimize noise highly recommended that shielded cable used, such type connect power evaluation board. Figure below shows functional block diagram HFA3524 Dual Synthesizer.
Introduction
HFA3524 highly integrated Dual Frequency Synthesizer ideally suited communications applications. Synthesizer features include dual modulus prescaler simultaneous local oscillator generation using very stable digital phase locked loop technique. HFA3524 packaged TSSOP (Figure which will facilitate PCMCIA type applications. additional information individual datasheet spec number 4062.
