1.4.10 Antenna Control

T77H468 provides GPIO control signals for external antenna tuner application. The function

is under development for customization. ANTCTRL (0-3) are provided to allow for the

implementation of antenna tuning solutions. The number antenna control lines required will

depend on the application and antenna/band requirements.

An example of tuning state configuration as below.

1.4.11 Coexistence

COEX1, COEX2 and COEX3 are provided to allow for the implementation of wireless

coexistence solutions between the radio(s) on the M.2 Card and other off-card radio(s).

These other radios can be located on another M.2 Card located in the same host platform or

as alternate radio implementations (for example, using a PCI Express M.2 CEM or a

proprietary form-factor add-in solution).

Reserve for future extension, please contact with us if need to use these Pins.
