1.4.2 Power and ground
(1) Power Rail Parameters
Parameter Min Type Max Units
Operating voltage 3.135 3.3 3.465 Vdc
The operating voltage was defined in PCIe M.2_Rev0.7a standard as 3.3V+/-5%.
(2) 3.135 V is the minimum voltage supplied to LTE M.2 card by the host platform, and VCC
must never be under 3.135 V in any case. As our experiment, if we set the VCC=3.0V, the
M.2 card will power off when M.2 card working at +23dBm continue mode.
(3) Whenever the M.2 module works at 2G mode, the module transmits at the maximum
power (like +33dBm), the transient peak current may reach to 2.5 A.
We recommended design the VCC supply of host as below:
Remark: When the system power restarts, reserve R1 to discharge power.
(4) The LTE M.2 module provides 5 power pins and 11 Ground pins. To ensure that the LTE
module works normally, all the pins must be connected.
15
1.4.3 Full_Card_Power_Off
The M.2 LTE module can be controlled to power on/off by the Full_Card_Power_Of pin.
Item State M.2 card state
1 Low Powers off, It’s internally pulled down by 100K ohm resistor
2 High Powers on, it is 3.3V tolerant but can be driven by either 1.8V or
3.3V GPIO.
The recommended connections as below
1.4.4 USB interface
T77H468 module is compliant with USB2.0 in all three modes (Low speed, Full speed, and
high speed). When two devices are connected via a USB interface, one of the devices must
act as a host, and the other device must act as a peripheral. The host is responsible for
initiating and controlling traffic on the bus.
Figure 1-4-4 USB2.0 interface
16
1.4.5 W_DISABLE#
This control setting is implementation-specific and represents the collective intention of the
host software to manage radio operation. T77H468 provides a hardware pin (W_DISABLE#)
to disable or enable the radio. Besides, the radio can also be enabled or disabled through
software AT commands.
Item State Function (WWAN state)
W_DISABLE#1
Low WWAN Disabled (no RF operation allowed)
High WWAN Enabled (RF operation allowed), internally pull up
W_DISABLE#2
Low GPS Disabled (no RF operation allowed)
High GPS Enabled (RF operation allowed), internally pull up
1.4.6 LED Indication
The LED signal is provided to enable wireless communication add-in cards to provide status
indications to users via system provided indicators
(1) State of the LED# pin
Item State Definition Interpretation
1 Low The LED is emitting light. Radio is capable of transmitting.
2 High The LED is emitting no light. Radio is incapable of transmitting.
(2) Typical LED Connection in Platform/System
.
17
1.4.7 WoWWAN
The WAKE_ON_WWAN# signal is for power saving.
•LTE module always listening at very low power in idle mode
•LTE module will wake up mother board via ‘WoWWAN’ signal.
•The platform will power on when triggered by the LTE module.
The WAKE_ON_WWAN# signal is used to wake up the host. It is open drain and should be
pulled up at the host side. When the WWAN needs to wake up the host, it will output a one
second low pulse, shown in Figure 1-4-6.
Typical Connection in Platform/System
18
1.4.8 DPR (Dynamic Power Reduction)
The optional DPR signal is used by wireless devices to assist in meeting regulatory SAR
(Specific Absorption Rate) requirements for RF exposure. The signal is provided by a host
system proximity sensor to the wireless device to provide an input trigger causing a
reduction in the radio transmit output power.
The required value of the power reduction will vary between different host systems and is
left to the host platform OEM and card vendor to determine, along with the specific
implementation details. The assertion and de-assertion of DPR is asynchronous to any
system clock. All transients resulting from the proximity sensor need to be de-bounced by
system circuitry.
(1) State of the DPR
Item State Definition Interpretation
1 Low
Enable the SAR power back off.
Radio is capable of transmitting.
2 High
Disable the SAR power back off,
internally pull up
Radio is incapable of transmitting.
(2) Typical Connection in Platform/System
Remark:
a. The proximity sensor was controlled by the platform side.
b.
After DPR pin becomes low level, you can set the MAX TX power by AT commands..
19
1.4.9 USIM
The UIM contains parameters necessary for the WWAN device’s operation in a wireless
wide area network radio environment. The UIM signals are described in the following
paragraphs for M.2 add-in cards that support the off-card UIM interface.
(1) USIM card socket
It is recommended to take electrostatic discharge (ESD) protection measures near the USIM
card socket. The USIM socket should be placed near the NGFF interface (<100 mm),
because a long circuit may impact signal quality.
(2) UIM-PWR
UIM_PWR power supply can supply 1.8 V and 2.85 V power to UIM card and auto detects
follow SIM card type
(3) SIM Detect
This signal is used to detect the insertion and removal of a SIM device in the SIM socket.
With a Normal Short SIM Card connector, PUSH-PUSH type, the detect switch is normally
shorted to ground when no SIM card is inserted. When the SIM is inserted, the
SIM_DETECT will transition from logic 0 to logic 1 state. The rising edge will indicate
insertion of the SIM card. When the SIM is pulled out, the SIM_DETECT will transition from
logic1 to logic 0. This falling edge will indicates the pulling out of the SIM card. The M.2
module monitoring this signal will treat the rising/falling edge or the actual logic state as an
interrupt, that when triggered, the module will act accordingly.
20
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.

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).

1.4.12 RESET#
Asynchronous RESET# pin, active low. Whenever this pin is active, the modem will
immediately be placed in a Power On reset condition. Care should be taken not to activate
this pin unless there is a critical failure and all other methods of regaining control and/or
communication with the WWAN sub-system have failed.
The Reset# signal is relatively sensitive, it is recommended to install one capacitor
(10~100pF) near to the M.2 card pin.

2.2 RF transceiver
The WTR1605 device is a highly integrated and versatile RF CMOS transceiver IC that can
be used in multimode, multiband applications – including Rx diversity. The WTR1605 IC is
the RF transceiver IC within compatible Qualcomm MDM9615 chipsets.
The WTR1605 IC integrates advanced receive and transmit features into a 4.91 × 5.47 ×
0.63 mm package to simplify handset design, minimize parts count, and reduce DC power
consumption. These advanced Rx/Tx features include:
Multimode, multiband RF transceiver functions:
GNSS receiver functions
Fully integrated LO generation and distribution circuits to support all the RF operating
band and mode combinations
Primary, diversity, and GNSS receivers that can operate simultaneously
Tx power detector for monitoring the transmit power levels
The GSM receiver can share the secondary paths with CDMA, WCDMA, and LTE
diversity receivers
Qualcomm’s intelligent receiver technology for CDMA modes:
Low operating voltages that help save battery current and allows the WTR IC power to
be supplied by the PMIC’s switching mode power supply (SMPS) circuits for even
greater power savings
