SP5668 2.7GHz 3-Wire Bus Controlled Synthesiser

The SP5668 contains all the elements necessary, with the exception of a frequency reference, loop filter and external high voltage transistor, to control a varicap tuned local oscillator, so forming a complete PLL frequency synthesised source. The device allows for operation with a high comparison f.

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 .
