2.2.1 RF functionalities

The Radio Frequency (RF) range comply with the Phase II EGSM 900/DCS 1800 and GSM 850/PCS 1900 recommendation. The frequencies are :

Transmit band (Tx) Receive band (Rx)

GSM 850 824 to 849 MHz 869 to 894 MHz

E-GSM 900 880 to 915 MHz 925 to 960 MHz

DCS 1800 1710 to 1785 MHz 1805 to 1880 MHz

PCS 1900 1850 to 1910 MHz 1930 to 1990 MHz

The Radio Frequency (RF) part is based on a specific quad band chip including:

 a Digital low-IF receiver  a Quad-band LNAs (Low Noise Amplifier)  an Offset PLL (Phase Locked Loop) transmitter  a Frequency synthesizer  a Digitally controlled crystal oscillator (DCXO)  a Tx/Rx FEM ( Front-End Wireless CPU) for quad-band GSM/GPRS

2.2.2 Baseband functionalities

The digital part of the WISMO Quik Q2686 is composed of a PCF5212 PHILIPS chip. This chipset is using a 0,18 µm CMOS mixed technology, which allows massive integration as well as low current consumption.

2.3 Operating System

WISMO Quik Q2686 is designed to integrate various types of specific process

applications such as vertical applications (telemetry, multimedia, automotive…).

The Operating System offers a set of AT commands to control the Wireless CPU. With this standard Operating System, some interfaces of the Wireless

CPU are not available since they are dependent on the peripheral devices

connected to the Wireless CPU.

The Operating System is Open AT®compliant.

3.2 Power supply

3.2.1 Power supply description

The power supply is one of the key issue 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 the peaks the ripple (U the supply voltage must not exceed a certain limit (see Table 1 Power supply voltage“ Power Supply Voltage”).

 In communication mode, a GSM/GPRS class 2 terminal emits 577µs

radio bursts every 4.615ms. (See Figure 2)

) on

Figure 2 : Power supply during burst emission

 In communication mode, a GPRS class 10 terminal emits 1154µs radio

bursts every 4.615ms.

Only the VBATT power supply input is necessary to provide the Q2686 Wireless CPU.

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) flows with a ratio of:

o 1/8 of the time (around 577µs every 4.615ms for GSM /GPRS cl. 2)

and

o 2/8 of the time (around 1154µs every 4.615ms for GSM /GPRS cl.

10).

The rising time is around 10µs.

 is internally used to provide through several regulators, the power

supply VCC_2V8 and VCC_1V8 needed for the base band signals.

When supplying the Wireless CPU with a battery, the total impedance (battery+protections+PCB)should be <150 mOhms.

When the Wireless CPU is in Alarm mode, no voltage must be applied on any pin of the 100-pin connector excepted on the BAT-RTC (pin 7 ) for RTC operation, or ON/~OFF (pin 19) to power ON the Wireless CPU.

3.2.2 Power consumption

The power consumption is depending of the configuration used. That’s why, the following consumption values are given for each modes, RF bands and software used (AT or Open AT™).

All following information are given assuming a 50  RF output.

The following consumption values are given by measurement on Wireless CPU samples, at temperature of 25°C.

Three VBATT values are used to measure the consumption, VBATT VBATT

(4.8V) and VBATT

The average current is given for the three VBATT values and the peak current given is the maximal current peak measured with the three VBATT voltages.
