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 which can be disabled for applications up to 2GHz so enabling a step size equal to the comparison frequency up to 2GHz and twice the comparison frequency up to 2.7GHz. Comparison frequencies are obtained either from a crystal 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.
