3.3V/5VProgrammable 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. Output

frequency steps of 250 KHz, 500 KHz, 1.0 MHz, 2.0 MHz can be

achieved using a 16 MHz crystal, depending on the output dividers

settings. The PLL loop filter is fully integrated and does not require

any external components.

• Best−in−Class Output Jitter Performance, ±20 ps Peak−to−Peak
