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.
