Boxing Two Synthesizer modules
1U Rack mountable Ethernet Controlled Synthesizer
The first module is a 1U rack mountable device which is actually used as the main dual clock distributor in
the BEST-2 rack in the northern cross control room at Medicina. The 10 MHz input reference is generated
by the Medicina Maser Atomic Clock while the dual outputs serves directly a ROACH board equipped with
two 8 bit 1Gbps ADCs. These output can be replicated by connecting them to the local clock distributor
which amplifies and splits the sine waves to serve more devices depending on the project.
Looking at the pictures you can see the basic elements within the box and the simple links where the red
wires are 5 Volts distribution, the yellow twisted with the black ground is the 12 Volts, the group of yellow
wires are the serial data over the RS-232 protocol and blue/brown the 220 Volts line. The 12 Volts are
generated by a switching power supply fully encapsulated, the Traco Power TMLM 10112 (AC/DC Power
Modules, Input 100-240VAC, 50-60Hz, Output 12VDC / 833mA), then the regulator 7805 generates the +5V
(a fan module working at 12V has been placed above its heat sink).
