SP5668

2.7GHz 3-Wire Bus Controlled Synthesiser

Preliminary Information

DS4538 - 1.6 January 1997

The SP5668 is a single chip frequency synthesiser

designed for tuning systems up to 2.7GHz.

The RF preamplifer contains a divide by two prescaler

whichcanbedisabledforapplicationsupto2GHzsoenabling

controlled on–chip oscillator or from an external source.

The device contains three switching ports, P0 – P2,

together with an ’in–lock’ flag output. Various test modes

including varactor disable and charge pump disable are also

included.
