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 frequency by 2, and with a 16MHz
external quartz crystal used to provide the reference
frequency, the output frequency can be specified in 1MHz
steps.
