4.2.4 MAKO
MAKO IC (U1402M1) is a customized IC and the SCM uses this device to leverage some unique
functionality that it provides.
Most of the MAKO functionality are not used on the SCM. Only the MAKO codec, USB driver, ADC,
DAC, and some voltage regulators are used for MTR3000 base station/repeater. The 9 channel
general purpose ADC is used for various controller metering.
Refer to Figure 4-4 for the MAKO block diagram and usage of MTR3000 Controller.
Note
For the OCXO kit, the controller must be warmed up for a minimum of 15 minutes before the
base station/repeater is enabled for transmit.
