DDS/PLL-based Programmable Frequency Synthesizer
Model DPL2.5G |
DPL-2.5G is wide band clock source utilizing DDS(Direct Digital Synthesis
and PLL(Phase Locked Loop) technique. It provides pure signal output from
700MHz - 2.5GHz in 10Hz steps.
The frequency can be controlled by serial data which can be connected to
PC communicationn port and can be memorized into EEPROM and in case of
setting the power off, and on again, the stored frequency can be output.
Frequency compensated internal 10MHz clock provide high stability in wide
range temparature.
In case the accurate 10MHz clock is available externally, the frequency
stability can be imprved.

OPTION Frequency setting board FIX-2.5G |
Frequency setting board FIX-2.5G can be set frequency easily with BCD switches.
A frequency and setting value can be memorized with a save switch on the board.
When the module is used for itself, it is used as a memory setting tool of the parameter.
Just insert the module to the sockets of the board. Also, the detaching is easy.
