The SP5659 is a single chip frequency synthesiser designed
for tuning systems up to 2·7GHz.
The RF preamplifier drives a divide-by two prescaler which
can be disabled for applications up to 2GHz, allowing direct
interfacing with the programmable divider, resulting in a step
size equal to the comparison frequency. For applications up
to 2·7GHz the divide-by two is enabled to give a step size of
twice the comparison frequency.
The comparison frequency is obtained either from an on-
chip crystal controlled oscillator or from an external source.
The oscillator frequency F
REF
or the comparison frequency
F
may be switched to the REF/COMP output; this feature
is ideally suited to providing the reference frequency for a
second synthesiser such as in a double conversion tuner (see
Fig. 5).
The synthesiser is controlled via an I
2
C bus and responds
to one of four programmable addresses which are selected by
applying a specific voltage to the Address input. This feature
enables two or more synthesisers to be used in a system.
The SP5659 contains four switching ports, P0-P3 and a
5-level ADC, the output of which can be read via the I
2
C bus.
The SP5659 also contains a varactor line disable and
charge pump disable facility.
