SP5768  
3.0 GHz Low Phase Noise Frequency Synthesiser  
November 2004  
Features  
Ordering Information  
SP5768/KG/MP1S (Tubes)  
SP5768/KG/MP1T (Tape and Reel)  
Complete 3.0GHz single chip system  
Optimised for low phase noise, with comparison  
frequencies up to 4 MHz  
No RF prescaler  
Selectable reference division ratio  
Reference frequency output  
Description  
Selectable charge pump current  
Integrated loop amplifier  
The SP5768 is a single chip frequency synthesiser  
designed for tuning systems up to 3.0GHz and is  
optimized for low phase noise with comparison  
frequencies up to 4 MHz.  
Four switching ports  
Low power replacement for SP5658 and 5668  
Downwards software compatible with SP5658  
The RF programmable divider contains a front end dual  
modulus 16/17 functioning over the full operating range  
and allows for coarse tuning in the upconverter  
application and fine tuning in the downconverter.  
ESD protection, (Normal ESD handling  
procedures should be observed)  
Comparison frequencies are obtained either from a  
crystal controlled on-chip oscillator or from an external  
source. A buffered reference frequency output is also  
available to drive a second SP5768.  
Applications  
TV, VCR and Cable tuning systems  
Communications systems  
The device also contains 4 switching ports.
