NBC12429 Programmable PLL Synthesized Clock Generator

NBC12429 Programmable PLL Synthesized Clock Generator

The NBC12429 and NBC12429A are general purpose, Phase−Lock−Loop (PLL) based synthesized clock sources. The VCO will operate over a frequency range of 200 MHz to 400 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.
