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 by 1, 2, 4 or 8. 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.

APPLICATIONS

■ Workstations

■ Advanced communications

■ High end consumer

■ High-performance computing

■ RISC CPU clock

■ Graphics pixel clock

■ Test equipment

■ Other high-performance processor-based

applications
