The MFDR-101A is a master bus module for use in the MEDAU-2000 and MCDAU-2000 product families. The module provides two (2) adaptable pre-modulation filter outputs, each with independently programmable amplitude and offset. The MFDR-101A takes in the PCM data and clock from the MCDAU master unit (from modules such as the MMCI-105, MWCI-105, MWCI-120 and MPSO-102) and provides filtered PCM output(s) to the transmitter(s).
