Hopping synthesizer controller interface board design for Skynet uplink trials / by Lloyd Mason. : Co24-3/7-98-005E-PDF
"In this report the design of an integrated circuit board for use in the payload of an extremely high frequency satellite communications experiment is described. This board, called the hopping synthesizer controller interface (HSCI) board, provides all necessary clock signals for the payload as well as the means to control the hopping synthesizer controller used in dehopping the received signal at the payload. Most of the integrated circuits on this board are standard off-the-shelf 7400 series transistor-transistor logic devices. The complexity of the printed circuit board (PCB) is greatly reduced by using two erasable programmable logic devices (EPLDs). One of these EPLDs derives all of the necessary clock signals from a single crystal oscillator. The other EPLD provides a board addressing capability as well as a strobe signal to control the hopping synthesizer controller. Two different versions of the HSCI board were built, one was a speed-wrap prototype version while the other was the finalized PCB version. Both boards were found to operate reliably and to meet expected performance"--Abstract, page iii.
