SP5054

2.6GHz 3-Wire BUS Controlled Synthesiser

DS3048 - 3.4 May 1996

TheSP5054isasingle-chipfrequencysynthesiserdesigned

for satellite TV tuning systems. It is a programming variant of

theSP5055,allowingthedesignofonetunerwitheitherI²Cbus

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

programmableopen-collectoroutputsareincluded.Thedevice

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.
