... PROGRAMMABLE FREQUENCY SYNTHESIZER (50MHz to 950MHz) DESCRIPTION The SY89430V 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 950MHz. The differential PECL output can be configured to be the VCO frequency divided ...

... M register with the final eight bits of the data stream on the S_ the most significant bit is loaded first (T2, N1 and M8). When T[2:0] is set to 100 the SY89430V is placed in PLL bypass mode. In this mode the S_ into the M and N dividers. The N divider drives the FOUT differential pair and the M counter drives the TEST output pin ...
