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.
FEATURES

ELECTRICAL CHARACTERISTICS (continued)
TAMB = 120°C to +80°C, VCC = +4.5 to +5.5V. Reference frequency = 4MHz. These characteristics are guaranteed by either
production test or design. They apply within the specified ambient temperature and supply voltage ranges unless otherwise
stated.
