Frequency to Voltage Converter Analog Front-End Prototype
The device compares multiple filter circuits side-by-side.
The frequency to voltage converter
analog front end evaluation prototype
(F2V AFE) is an evaluation board
designed for comparison of different
methods of accurately extracting the frequency
of a sinusoidal input signal. A
configurable input stage is routed to one

Dust-Tolerant Intelligent Electrical Connection System
This technology has application in aerospace, military, homeland security, mining, and oil and
gas exploration operations that are conducted in uncontrolled environments.
Faults in wiring systems are a serious
concern for the aerospace and aeronautic
(commercial, military, and civilian)
industries. Circuit failures and vehicle
accidents have occurred and ...

Gigabit Ethernet Asynchronous Clock Compensation FIFO
Clock compensation for Gigabit
Ethernet is necessary because the clock
recovered from the 1.25 Gb/s serial data
stream has the potential to be 200 ppm
slower or faster than the system clock.
The serial data is converted to 10-bit parallel
data at a 125 MHz rate on a clock
recovered from the ...

High-Speed, Multi-Channel Serial ADC LVDS Interface for Xilinx Virtex-5 FPGA
Analog-to-digital converters (ADCs) are used in scientific
and communications instruments on all spacecraft. As data
rates get higher, and as the transition is made from parallel
ADC designs to high-speed, serial, low-voltage differential signaling
(LVDS) designs, the need will arise to interface these in
field-programmable gate arrays (FPGAs). As Xilinx ...
