SP5748

2.4GHz Very Low Phase Noise PLL

Advance Information

DS4875 - 1.3 November 1998

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

frequenciesupto4MHz.Itisdesignedtobedownwards

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.
