NBC12429 Datasheet, PDF (1/20 Pages) ON Semiconductor – 3.3V/5V Programmable PLL Synthesized Clock Generator

NBC12429
3.3V/5V Programmable PLL
Synthesized Clock
Generator
25 MHz to 400 MHz
The NBC12429 is a general purpose, PLL based synthesized clock
source. The VCO will operate over a frequency range of 200 MHz to
400 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. Output frequency steps of
1.0 MHz can be achieved using a 16 MHz crystal, depending on the
output dividers. The PLL loop filter is fully integrated and does not
require any external components.
