These power consumption values assume that Ethernet is disabled.
Ethernet draws approximately 220 mw. If you require a reduced power
consumption, turn off the Ethernet port as outlined in Chapter 6, Ethernet
Configuration on 73 and commands described in the OEM6 Family Firmware
The above values can change with the number of satellites in view and the
firmware version. Use them as a guide for what you might expect but not as
absolute values

CONNECTORS
MMCX female
Connections between the MMCX and an external oscillator, or interface board,
must be impedance controlled. To accomplish this use 50 ohm coaxial cable
and 50 ohm connectors.
External Clock input
Refer to the
EXTERNALCLOCK
command
