7.1.4 DC/DC module
The DC/DC module is a continue power voltage converter from an external
power source to the internal power level of ECOS-D devices. The converter,
other than the power voltage conversion, is able to galvanically insulate
(1500Vrms) the internal 12Vdc power distribution from the external power
source and a 28Vdc power distribution to the 110W PA module.
7.1.5 Synchronization module - SYNC
The "Synchronization” (SYNC) module is the module that is able to manage network
synchronisation for ECOS-D equipment. This module is equipped with devices for numerical
computation (DSP, FPGA) and control (microprocessor) combined with the electrical
interfaces to the GPS antenna.
The extreme versatility of this module allows you to synchronize the ECOS-D RBS using
different reference sources.
The module is able to receive the input reference source from multiple clock signals:
• Internal GPS receiver
• AF tone (eg, tone at 3400 Hz via from an external source through LIF or DIF
module)
