This product is installed into an RF Power Amplifier chassis to allow
the PA to communicate with the General Dynamics DMR (Digital Modular
Radio) system via the GDDS proprietary Ethernet interface. The PEP
(Programmable Ethernet Port) board is a proven low-risk approach for
new power amplifier vendors and has already been qualified as being
compliant with the GDDS specifications in terms of timing, frequency
hopping, and proprietary Ethernet message protocol. The PEP board works
with HF and VHF/UHF PA designs.
The PEP board contains a PowerPC processor, Flash, SDRAM, FPGA,
Ethernet, and DPRAM interfaces. The FPGA provides for filtering and
processing of Ethernet messages necessary to comply with the GDDS
timing requirements for frequency hopping power amplifiers. The PEP
board communicates with the PA controller via a DPRAM interface and can
be easily incorporated into most PA designs. The PEP board requires
external 3.3V and 5.0V power and HED can design it to fit nearly any
desired board outline.
