MC12429

The MC12429 is a general purpose synthesized clock source. MC12429's internal VCO will operate over a range of frequencies from 200 to 400MHz. The differential PECL output can be configured to be the VCO frequency divided by 1, 2, 4, or 8. With the output configured to divide the VCO frequency by 1, and with a 16.000MHz external quartz crystal used to provide the reference frequency, the output frequency can be specified in 1MHz steps. The PLL loop filter of MC12429 is fully integrated so that no external components are required. The output frequency is configured using a parallel or serial interface.
