User Manual

18. Console port (UART)
The console port of the module is provided on the module and also through pin 37 (1_AGPIO_B_8) and
pin 40 (1_AGPIO_B_0) of the mPCIe interface. Host processor can communicate to the module through
the console port.
1_AGPIO_B_8 – UART TX signal
1_AGPIO_B_0 – UART RX signal (1K pull up resistor is required at pin 40 of mPCIe connector on the host
processor board)
19. EMI and Antenna isolation requirement
This module is a 5GHz only radio and requires 25dB isolation from 2.4GHz antenna when dual band dual
concurrent mode is supported in the final product. Otherwise, the throughput performance will be
degraded due to harmonics of 2.4GHz leaking into the 5GHz radio band.
The SoC motherboard typically consists of many subsystems such as DDR2, DDR3, A/VDSL, VOIP, USB
and other high speed interfaces. Each subsystem will operate on different clock frequencies and its
harmonics could fall into the 5GHz band. Please make sure the EMI radiated from different clocks on the
board can be contained or mitigated by either HW or SW solution.
