NBC12430 Datasheet, PDF (1/18 Pages) ON Semiconductor – 3.3V/5VProgrammable PLL Synthesized Clock Generator

NBC12430, NBC12430A
3.3V/5V Programmable PLL
Synthesized Clock
Generator
50 MHz to 800 MHz
The NBC12430 and NBC12430A are general purpose, PLL based
synthesized clock sources. 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.
