SP5769

3GHz I²C Bus Synthesiser

Preliminary information

DS4878 Issue 4.0 October 1999

Features

Ordering Information

G Complete 3·0 GHz Single Chip System

G Optimised for Low Phase Noise, with Comparison

Frequencies up to 4 MHz

SP5769A/KG/MP1S (Tubes)

SP5769A/KG/MP1T (Tape and Reel)

SP5769A/KG/QP1S (Tubes)

G No RF Prescaler

SP5769A/KG/QP1T (Tape and Reel)

G Selectable Reference Division Ratio

G Selectable Reference/Comparison Frequency Output

G Selectable Charge Pump Current with 10:1 Ratio

G Four Selectable I²C Addresses

size equal to the loop comparison frequency and no

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

G I²C Fast Mode Compliant with 3·3V and 5V Logic Levels

G Four Switching Ports

G Functional Replacement for SP5659 (except ADC)

G Pin Compatible with SP5655

G Power Consumption 110mW with V_CC= 5·5V, all Ports off

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

Cat.1 (Normal ESD handling procedures should be

observed)

255°C to 1125°C

The SP5769 is a single chip frequency synthesiser

designed for tuning systems up to 3GHz. The RF

preamplifier interfaces direct with the RF programmable

divider, which is of MN1A construction so giving a step
