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.
