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
