NBC12439 Datasheet, PDF (1/20 Pages) ON Semiconductor – 3.3 V/5 V Programmable PLL Synthesized Clock Generator

NBC12439
3.3 V/5 V Programmable
PLL Synthesized Clock
Generator
50 MHz to 800 MHz
The NBC12439 is a general purpose, PLL based synthesized clock
source. The VCO will operate over a frequency range of 400 MHz to
800 MHz. The VCO frequency is sent to the N-output divider, where
it can be configured to provide division ratios of 1, 2, 4 or 8. The VCO
and output frequency can be programmed using the parallel or serial
interfaces to the configuration logic. The PLL loop filter is fully
integrated and does not require any external components.
