SP5054
2.6GHz 3-Wire BUS Controlled Synthesiser
DS3048 - 3.4 May 1996
The SP5054 is a single-chip frequency synthesiser designed
for satellite TV tuning systems. It is a programming variant of
the SP5055, allowing the design of one tuner with either I2C bus
or 3-wire bus format, depending on which device is inserted.
The SP5054, when used with a satellite varactor tuner, forms
a complete phase locked loop tuning system.
The circuit consists of a divide-by-16 prescaler with its own
preamplifier and a 14/15-bit programmable divider controlled
by a serially-loaded data register. Four independently
programmable open-collector outputs are included. The device
has four modes of operation, selected by the Mode Select
input; these modes are summarised in Table1.
The comparison frequencies are obtained by the division of
the output of a 4MHz crystal controlled on-chip oscillator. The
phase comparator has a charge pump output with an output
amplifier stage around which feedback may be applied. Only
one external transistor is required for varactor line driving.
