The comparison frequency is obtained either from an
on–chip crystal controlled oscillator, or from an external
source. The oscillator frequency Fref or the comparison
frequency F may be switched to the REF/COMP
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. 8).
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.
Description
The SP5669 is a single chip frequency synthesiser
designed for tuning systems up to 2.7GHz and offers
step size compatible with DTT offset requirements.
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 so enabling a step size equal to the comparison
frequency. For applications up to 2.7GHz the divide by
two is enabled, giving a step size of twice the
comparison frequency.
The device contains four switching ports P0–P3 and a
5–level ADC. The output of the ADC can be read via the
I2 C
bus.
The device also contains a varactor line disable and
chargepump disable facility.
