1.2.1 RF functionalities
The Radio Frequency (RF) functionalities comply with the Phase II E-GSM 900/DCS 1800 and GSM
850/PCS 1900 recommendation.
The frequencies are:
Q2406
• Rx (E-GSM 900): 925 to 960 MHz.
• Rx (DCS 1800): 1805 to 1880 MHz.
• Tx (E-GSM 900): 880 to 915 MHz.
• Tx (DCS 1800): 1710 to 1785 MHz.
Q2426
• Rx (GSM 850): 869 to 894 MHz.
• Rx (PCS 1900): 1930 to 1990 MHz.
• Tx (GSM 850): 824 to 849 MHz.
• Tx (PCS 1900): 1850 to 1910 MHz.
The Radio Frequency (RF) part is based on a specific dual band chip including :
• Low-IF Receiver,
• Dual RF (Radio Frequency) synthesizer,
• Digital IF to Baseband Converter,
• Offset PLL (Phase Lock Loop) transmitter,
• 1 (logarithmic) Power Amplifier (PA) controller,
• Dual band Power Amplifier (PA) module.
1.2.2 Baseband functionalities
The digital part of the WISMO Quik Q24x6 sub-series is based on a PHILIPS-VLSI chip (ONE C
GSM/GPRS Kernel).
This chipset is using a 0.25 µm mixed technology CMOS, which allows massive integration as well
as low current consumption.

1.3 Firmware
WISMO Quik Q24x6 sub-series is designed to be integrated into various types of applications such
as handsets or vertical applications (telemetry, multimedia,…).
For vertical applications, the firmware offers a set of AT commands to control the module (for further
information, refer to document [3]).
Please be aware that some of these interfaces can not be handled when using the WISMO
Quik Q24x6 sub-series driven by AT commands: LCD interface, auxiliary serial link interface
and SPI bus.
AAA TTT
This symbol is used to indicate the interfaces not available with AT commands.
These functions have then to be managed externally i.e using the main processor of the
application.

2 Interfaces
Note:
Some of the WISMO interface signals are multiplexed in order to limit number of pins but this
architecture implies some limitation.
For example, in case of using SPI bus, 2-wire bus cannot be used.
Warning:
All external signals must be inactive when the WISMO module is OFF to avoid any damage
when starting and allow WISMO module to start correctly.
2.1 General Purpose Connector (GPC)
A 60-pin connector, with 0.5 mm pitch, is provided to interface the WISMO Quik Q24x6 sub-series
with a board containing either a LCD module, or a keyboard, or a SIM connector, or a battery
connection...
The interfaces available on the GPC are described in the next paragraphs.
The GPC is made by KYOCERA / AVX group with the following reference:
14 5087 060 930 861.
The matting connector has the following reference:
24 5087 060 X00 861.
For further details, refer to paragraph 4.4 General Purpose Connector data sheet.

2.2 Power supply
2.2.1 General description
The power supply is one of the key issues in the design of a GSM terminal. Due to the bursted
emission in GSM / GPRS, the power supply must be able to deliver high current peaks in a short
time. During these peaks the ripple (U
in table “Power Supply Voltage” hereafter.
In communication mode, a GSM/GPRS class 2 terminal emits 577 µs radio bursts every 4.615 ms.
In communication mode, a GPRS class 10 terminal emits 1154 µs radio bursts every 4.615 ms.

Two different inputs are provided for the power supply:

• the second one, VDD is used to supply the baseband part.
Notes
:

• In case of separate power supplies, they have to be in the same state i.e both active or
inactive at the same time.
VBATT: supplies directly the RF components with 3.6 V. It is essential to keep a minimum voltage
ripple at this connection in order to avoid any phase error. The RF Power Amplifier current (2.0 A
peak in GSM /GPRS mode with a 50 Ohms RF output flows with a ratio of:
• 1/8 of the time (around 577 µs every 4.615 ms for GSM/GPRS class 2),
• 2/8 of the time (around 1154 µs every 4.615 ms for GSM/GPRS class 10).
The rising time is around 10 µs.
VDD: supplies the +2.8 V ballast regulators of the WISMO module. It is essential to keep the voltage
over 3.1 volts.
The WISMO module shielding case is the grounding. The ground has to be connected on the mother
board through a complete layer on the PCB.

2.6 Keyboard interface
Warning:
This interface is not FULLY available with AT commands:
An AT command allows to get the input key code (see AT+CMER command description). This
code has then to be processed by the application.
This interface provides 10 connections:
• 5 rows (ROW0 to ROW4),
• 5 columns (COL0 to COL4).
The scanning is a digital one, and the debouncing is done in the WISMO module. No discrete
components like R, C (Resistor, Capacitor) are needed.
