ORDERING INFORMATION
SP5748/KG/MP1S (Tubes)
SP5748/KG/MP1T (Tape and Reel)
The SP5748 is a single chip frequency synthesiser
designed for tuning systems up to 2.4 GHz and is
optimized for low phase noise with comparison
frequencies up to 4 MHz. It is designed to be downwards
software compatible with the 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.
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 SP5748.
The device also contains 2 switching ports.
