SP5848 3-Wire Bus Dual Low Phase Noise PLL

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 secti.

SP5848 Features

* Dual independent PLL frequency synthesisers in a single package, optimised for double conversion cable tuners, offering improved application 2.2GHz up-synthesiser optimised for low phase noise up to comparison frequencies of 4MHz 1.3GHz down-synthesiser optimised for low phase noise AND sm
