3. Modem Part (MDM9615)
The MDM9x40 is the latest-generation Qualcomm Technologies, Inc. (QTI) MDM device, which further expands
mass-market chipset capabilities by making 3G and 4G high-speed data services accessible to more consumers
in developed and developing countries. An MDM device is similar to a QTI MSM™ device, but without
multimedia logic.
The MDM9x40 chipset supports high-speed data capabilities over a wide range of air interface standards.
The MDM9x40 device is fabricated using the advanced 20 nm SoC CMOS process, and is available in the 8.6 ×
9.8 × 0.82 mm, 527-pin pico-scale package (527 PSP). It includes many ground pins for improved electrical
grounding, mechanical strength, and thermal continuity.
4. Power Management Part (PMD9645)
The PMD9645 device integrates all the wireless product’s power management, general housekeeping, and user
interface support functions into a single mixed-signal IC. Its versatile design is suitable for any multimode,
multiband product.
The PMD9645 mixed-signal BiCMOS device is available in the 103-pin wafer-level nanoscale package (103
WLNSP) that includes ground pins for improved electrical ground, mechanical stability, and thermal continuity.
- Input power management
- Output voltage regulation
- General housekeeping
- User interfaces
- IC interfaces

5. Clocks
The PMIC includes several clock circuits whose outputs are used for general housekeeping functions, and
elsewhere within the handset system. These circuits include a 19.2 MHz XO with multiple controllers and
buffers, an MP3 clock output, an RC oscillator, and sleep-clock outputs.
Performance specifications for these functions are presented in the following subsections.
- 19.2MHz : An external crystal is supplemented by on-chip circuits to generate the desired 19.2 MHz
reference signal. Using an external thermistor network, the on-chip ADC, and advanced temperature
compensation software, the PMIC eliminates the large and expensive VCTCXO module required by
previous-generation chipsets. The XO circuits initialize and maintain valid pulse waveforms, and
measure time intervals for higher-level handset functions. Multiple controllers manage the XO warmup
and signal buffering, and generate the desired clock outputs.

End Product Labeling
The module is labeled with its own FCC ID. If the FCC ID is not visible when the module is installed inside another
device, then the outside of the device into which the module is installed must also display a label referring to
the enclosed module. In that case, the final end product must be labeled in a visible area with the following:
Contains FCC ID: BEJGEN11NAN

OEM Responsibilities to comply with FCC Regulations
The module has been certified for integration into products only by OEM integrators under the following
condition: - The antenna(s) must be installed such that a minimum separation distance of at least 20 cm is
maintained between the radiator (antenna) and all persons at all times.
- The transmitter module must not be co-located or operating in conjunction with any other antenna or
transmitter except in accordance with FCC multi-transmitter product procedures. As long as the two condition
above is met, further transmitter testing will not be required. However, the OEM integrator is still responsible
for testing their end-product for any additional compliance requirements required with this module installed
(for example, digital device emissions, PC peripheral requirements, etc.).
“The OEM integrator has to be aware not to provide information to the end user regarding how to install or
remove this RF module or change RF related parameters in the user manual of the end product.”
IMPORTANT NOTE: In the event that these conditions can ’ t be met (for certain configurations or co-location
with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can’t be used
on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end
product (including the transmitter) and obtaining a separate FCC authorization.
Manual Information To the End User
This device complies with part 15 of the FCC rules Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
