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 MN1A construction so giving a step
size equal to the loop comparison frequency and no

prescaler phase noise degradation over the full RF
operating range. The comparison frequency is obtained
either from an on-chip crystal controlled oscillator, or from
an external source. The oscillator frequency, f
REF
, or phase
comparator frequency, f
COMP
, can be switched to the REF/
COMP output providing a reference for a second
frequency synthesiser. The synthesiser is controlled via
an 1

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.
