3.3 V/5 V Programmable
PLL Synthesized Clock
Generator
50 MHz to 800 MHz
http://onsemi.com
The NBC12430 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. Output frequency steps of
250 KHz, 500 KHz, 1.0 MHz, 2.0 MHz can be achieved using a
16 MHz crystal, depending on the output dividers settings. The PLL
loop filter is fully integrated and does not require any external
components.
