OPERATION
POWER SUPPLY
The MRT device has separate power supply pins labeled VDD and VAGC. The VAGC supply pin is connected
to the internal AGC amplifier and requires isolation from the VDD supply as indicated in Figure 10. Separate
bypass networks must be used for connecting the VDD and VAGC supply pins on the MRT to +5V. The bypass
network on the VAGC pin consists of an IN4148 or IN914 diode, and a 10/6.3 volt microfarad (tantalum) capac-
itor connected in parallel with a 0.1 microfarad capacitor, as shown in Figure 10. TranSwitch recommends that
the 0.1 microfarad decoupling capacitors be of RF quality and that they be connected in close proximity to the
device.
