NBC12439FNR2 - Brand New onsemi Clock Generators / Frequency Synthesizers / PLL
-
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 PLL loop filter is fully integrated and does not require any external components.
