Preliminary Information

SP5848

2.2/1.3GHz 3-Wire Bus Dual Low Phase Noise PLL

Preliminary Information

Features

G Dual independent PLL frequency synthesisers in a

single package, optimised for double conversion

cable tuners, offering improved application

G 2.2GHz up-synthesiser optimised for low phase

noise up to comparison frequencies of 4MHz

Ordering Information

SP5848/KG/QP1S

SP5848/KG/QP1T

Applications

G TV, VCR, and cable tuning systems

The SP5848 is a dual PLL frequency synthesizer

controlled by a 3-wire bus optimised for application in

double conversion tuners.

Each synthesiser loop within the SP5848 is

independently addressable and contains an RF

programmable divider, phase/frequency detector and

charge pump/loop amplifier section; a common

reference frequency oscillator and divider chain is

provided, whose ratios for each loop are independently

programmable.

Both synthesisers are optimised for low phase noise

performance and in addition synthesiser 2 is capable of

operation with a low comparison frequency.

G 1.3GHz down-synthesiser optimised for low phase

noise AND small step size

G Common reference oscillator and divider with

independently selectable ratios for each

synthesiser

G 10:1 programmable charge pump current ratio in up

synthesiser

G 3-Wire bus programmable, each synthesiser

indepently addressable

G Low power consumption, typ 100mW at 5V

G ESD protection, (Normal ESD handling procedures

should be observed)
