standard (T=0, T=1) and a single-wire protocol (SWP) interface for communication

The detail implementation and requirement needs be engaged and discussed with customer

1.5.10 Antenna Control

(1).T77W968 provides GPIO control signals for external antenna tuner application.

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. We will provide a tool to fill antenna control table in ODM factory to enable

antenna tuner support on specific platforms.

Foxconn general design for WWAN module with two control signals for reference only.

0 0 880 ~ 960 Band8 (WCDMA) + GSM900 + High Bands

0 1 791 ~ 894 Band5 (WCDMA, LTE) + GSM850 + High Bands

1 0 746 ~787 Band13 (LTE) + High Bands

1 1 704 ~746 Band17 (LTE) + High Bands

(2). T77W968 also provides MIPI interface (VIO=1.8V) for external antenna tuner application.

The function is under development for customization. M.2 pin.56 (MIPI_DATA), 58(MIPI_CLK)

M.2 pin.20/24 (antenna tuner Power) are provided to allow for the implementation of antenna

tuner solutions with variable capacitors. We will provide a tool to fill MIPI registers in ODM

factory to enable antenna tuner support on specific platforms.

Pin No. I/O Description Remark

56 I/O MIPI Data For external antenna tuner

58 I/O MIPI Clock For external antenna tuner

20 Power VIO=2.7V For antenna tuner power

24 Power VIO=1.8V For antenna tuner power

1.5.11 Antenna Tuner Mode Switch

T77W968 provide two antenna tuner modes configure for Notebook and Tablet scenario

through M.2 Pin22 (ANT_TUNER_CONFIG), and get more benefit on antenna performance

Item Pin 22 State

Tuner Mode Scenario

1 Low 0 For Notebook

2 High 1 For Tablet

1.5.12 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).
