Terrestrial Television Applications

• Selectable Reference Division Ratio, Compatible with

DTT Requirements

• Optimised for Low Phase Noise, with Comparison

Frequencies up to 4 MHz

• No RF Prescaler

• Selectable Reference/Comparison Frequency Output

prescaler phase noise degradation over the full RF

operating range. The comparison frequency is obtained

either from an on-chip crystal controlled oscillator, or from

an external source. The oscillator frequency, f_REF, or phase

comparator frequency, f_COMP, can be switched to the REF/

COMP output providing a reference for a second

frequency synthesiser. The synthesiser is controlled via

an 1²C bus and is fast mode compliant. It can be hard

wired to respond to one of four addresses to enable two

or more synthesisers to be used on a common bus. The

device contains four switching ports P0 - P3.

• Four Selectable I²C Addresses

• I²C Fast Mode Compliant with 3·3V and 5V Logic

Levels

• Four Switching Ports

• Functional Replacement for SP5659 (except ADC)

• Pin Compatible with SP5655

• Power Consumption 120mW with V_CC= 5·5V, all Ports off

• ESD Protection 2kV min., MIL-STD-883B Method 3015

Cat.1 (Normal ESD handling procedures should be

observed)

Description

The SP5730 is a single chip frequency synthesiser

designed for tuning systems up to 1·3GHz and is

optimised for digital terrestrial applications. The RF

preamplifier interfaces direct with the RF programmable

divider, which is of MN1A construction so giving a step

size equal to the loop comparison frequency and no
