Preliminary
General Description
Features
The GD90590 Evaluation Board is de-
signed for testing the performance of the
high-speed integrated device GD16590,
a high-speed clock synthesizer with PLL.
The GD16590 generates six differential
high-speed clocks from a common on-
chip VCO or an external VCXO. The
on-chip integrated PLL locks the outputs
to one of three selectable input reference
clocks.
All outputs are DC terminated on the
evaluation board.
During the board design special attention
has been paid to optimise the overall per-
formance, with consideration of the
GD16590’s linear characteristics.
De-coupling capacitors are located as
close as possible to the device, and the
signal carrying traces in the PCB are
kept free from via holes, sharp corners
etc. to make the transmission line design
as smooth as practically possible.
l Easy evaluation of high-speed perfor-
mance in carefully designed PCB.
l High-speed data in/outputs available
via standard SMA connectors.
l Integrated 50 W transmission lines in
the PCB ensure matching intercon-
nection of input and output signals.
l Input and output signals are AC
coupled, i.e. the device can be used
with circuits with positive as well as
negative supply.
l Single unregulated power supply:
+6 V, 400 mA.
l Board dimensions: 101 × 133 mm
incl. connectors.
l Gerber files for PCB layout available
on request.
