4: Electrical Specifications

The system block diagram in Figure 4-1 represents the MC7710

module integrated into a host system. The module includes the

following interfaces to the host:

• Power — Supplied to the module by the host.

• W_DISABLE_N — Active low input from a hardware switch to the

MC7710 that disables the main RF radio.

• GPS_EN_N — Active low input from a hardware switch to the

MC7710 that disables the GPS radio.

• WAKE_N— Signal used to wake the host when specific events

occur.

• WLAN_LED_N — Active-low LED drive signal provides an

indication of RADIO ON state, either WAN or GPS.

• Antenna — Three U.FL RF connectors (two for Rx / Tx, and one for

GPS). For details, see RF Specifications on page 39.

Note that GPS can use either the dedicated GPS port, or the

diversity/

MIMO port. GLONASS is supported only on the

dedicated GPS port.

• SIM — Supported through the interface connector. The SIM

cavity / connector must be placed on the host device for this

feature.

• USB — Interface to the host for data, control, and status infor-

mation.

• GPIO — Four GPIOs reserved for future use.

The MC7710 has two main interface areas — the host I/O connector

and the

RF ports. Details of these interfaces are described in the

sections that follow.
