1.3GHz Low Phase Noise Frequency Synthesiser
Preliminary Information
Description
The SP5730 is a single chip frequency synthesiser
designed for tuning systems up to 1.3GHz and is
optimised for digital terrestrial applications.
The RF preamplifier interfaces direct with the RF
programmable divider, which is of MN+A construction
so giving a step size equal to the loop comparison
frequency and no prescaler phase noise degradation
over the RF operating range.
The comparison frequency is obtained either from an
on-chip crystal controlled oscillator, or from an external
source. The oscillator frequency, Fref, or phase
comparator frequency, Fcomp, can be switched to the
REF/COMP output providing a reference frequency for
a second frequency synthesiser.
The synthesiser is controlled via an I
2
C bus and is fast
mode compliant. It can be hard wired to respond to one
of four addresses to enable two or more synthesisers to
be used on a common bus.
The device contains four switching ports P0-P3.
