SY89429A - Micrel Semiconductor

SY89429A PROGRAMMABLE FREQUENCY SYNTHESIZER

The SY89429A is a general purpose, synthesized clock source targeting applications that require both serial and parallel interfaces. Its internal VCO will operate over a range of frequencies from 400MHz to 800MHz. The differential PECL output can be configured to be the VCO frequency divided by 2, 4, 8 or 16. With the output configured to divide the VCO freq.
