摘要

This paper presents the design, operation and test results of a multichannel programmable distribution amplifier. The distributor is based on a reprogrammable device Spartan-6 FPGA (Xilinx) and is intended to distribute a 10 MHz or 5 MHz frequency reference signal as well as 1 PPS pulses. It is built in a 2U, 19" rack-mount enclosure and is equipped with a single optical and seven electrical inputs, as well as two optical and fourteen electrical outputs The transition time and additive jitter of the distribution amplifier were tested and they did not exceed 14 ns and 4.5 ps RMS (for electrical inputs/outputs), respectively. In the case of optical input/outputs, the results depend on the parameters of converters involved. The values of delays and jitter introduced by the distributor are slightly larger than for dedicated integrated circuits, but the advantage of this solution is the possibility to build signal distributors with a larger number of inputs/outputs and the ease to modify and meet requirements of various applications.
