Description

The NBC12439 is a general purpose, PLL based synthesized clock ource. The VCO will operate over a frequency range of 400 MHz to 00 MHz. The VCO frequency is sent to the N-output divider, where NBC12439 can be configured to provide division ratios of 1, 2, 4 or 8. The VCO nd output frequency can be programmed using the parallel or serial nterfaces to the configuration logic. The PLL loop filter is fully ntegrated and does not require any external components.
