Description:

2.4ghz very low phase noise pll.

SP5748, 2.4GHz Very Low Phase Noise PLL

The SP5748 contains all the elements necessary, with the exception of a frequency reference, loop filter and external high voltage transistor, to control a varicap tuned local oscillator, so forming a complete PLL frequency synthesised source.

The device allows for operation with a high comparison f

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 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 f
