POWER REQUIREMENTS
Normal Mode: +3.3 VDC +5%/-3%
OEMV3 Compatibility Mode (power via main header): +4.5 VDC to 36 VDC
For best performance, NovAtel strongly recommends additional supply
bypassing as close as possible to the OEM638 supply pins.
For the 3.3V supply - minimum 22 uF in parallel with 0.1 µF
For the wide-range supply - minimum 44 uF in parallel with 0.1 µF

Power consumption values assume Ethernet is disabled. Ethernet
draws approximately 450 mW. If reduced power consumption is required, turn
off the Ethernet port as outlined in "Chapter Ethernet Configuration" on page
73 and the ETHCONFIG
Reference Manual (OM-20000129)
The above values can change with the number of satellites in view and the
firmware version. Use only as a guide and not as absolute values

current 0-200 mA maximum (supplied by card through center conductor of RF
connector)
CONNECTORS
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.
Refer to the EXTERNALCLOCK command
