Overview
NBC12439, NBC12439A 3.
3V/5V Programmable PLL Synthesized Clock Generator 50 MHz to 800 MHz Description The NBC12439 and NBC12439A 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 16 MHz, 8 MHz, 4 MHz, or 2 MHz can be achieved using a 16 MHz crystal, depending on the output divider settings.
The PLL loop filter is fully integrated and does not require any external components.
Features • Best--in--Class Output Jitter Performance, ±20 ps Peak--to--Peak • 50 MHz to 800 MHz Programmable Differential PECL Outputs • Fully Integrated Phase--Lock--Loop with Internal Loop Filter www.
