Description
Tuning Circuits With Prescaler
Manufacturer
Freescale Semiconductor, Inc
Datasheet
PLL Tuning Circuits
with I 2 C Bus
They contain on one chip all the functions required for PLL control of a VCO.
The integrated circuits also contain a high frequency prescaler and thus can
handle frequencies up to 1.3 GHz.
