1. Introduction

1.1 Purpose

This manual provides the information necessary to repair, calibration, description and download the features of the CE110.

1.2. Regulatory Information

A. Security

Toll fraud, the unauthorized use of telecommunications system by an unauthorized part (for example, persons other than your company’s employees, agents, subcontractors, or person working on your company’s behalf) can result in substantial additional charges you’re your telecommunications services. System users are responsible for the security of own system. There are may be risks of toll fraud associated with your telecommunications system. System users are responsible for programming and configuring the equipment to prevent unauthorized use. LGE does not warrant that this product is immune from the above case but will prevent unauthorized use of common-carrier telecommunication service of facilities accessed through or connected to it. LGE will not be responsible for any charges that result from such unauthorized use.

B. Incidence of Harm

If a telephone company determines that the equipment provided to customer is faulty and possibly causing harm or interruption in service to the telephone network, it should disconnect telephone service until repair can be done. A telephone company may temporarily disconnect service as long as repair is not done.

C. Changes in Service

A local telephone company may make changes in its communications facilities or procedure. If these changes could reasonably be expected to affect the use of the KE820/KG99 or compatibility with the network, the telep hone company is required to give advanced written notice to the user, allowing the user to take appropriate st eps to maintain telephone service.

D. Maintenance Limitations

Maintenance limitations on the CE110 must be performed only at the LGE or its authorized agents. The user may not make any changes and/or repairs expect as specifically noted in this manual. Therefore, note that un authorized alternations or repair may affect the regulatory status of the system and may void any remaining warranty.

E. Notice of Radiated Emissions

The CE110 complies with rules regarding radiation and radio frequency emission as defined by local regulatory agencies. In accordance with these agencies, you may be required to provide information such as the follo wing to the end user.

F. Pictures

The pictures in this manual are for illustrative purposes only; your actual hardware may look slightly different.

G. Interference and Attenuation

An CE110 may interfere with sensitive laboratory equipment, medical equipment, etc. Interference from unsuppressed engines or electric motors may cause problems.

H. Electrostatic Sensitive Devices

ATTENTION

Boards, which contains Electrostatic Sensitive Device(ESD), are indicated by the sign. Following information is ESD handling: Service personnel should ground themselves by usinga wrist strap when exchange system boards. When repairs are made to a system board, they should spread the floor with anti-static mat which is also grounded. Use a suitable, grounded soldering iron. Keep sensitive parts in these protective packages until these are used. When returning system boards or parts such as EEPROM to the factory, use the protective package as described.

3. Circuit Description

3.1 General Description

The RF part consists of a transmitter, a receiver, a synthesizer, a voltage supply and a DCXO part. The main RF Chipset B6PLD is a highly integrated RF tranceiver IC FOR Digital Interface of GSM 850, GSM900, DCS1800 and PCS1900 quad-band cellualr systems. The B6PLD incorporates EDGE tranceiver apability, quad R low-noise amplifiers(LNSa). Direct conversion mixers, a programmable gain amplifier(PGA) with DC offset and frequency response correction, ADC, Digital filiter, Digital Interface, fully integrated VCOs, an RF fractiona-N synthesiser, a low-noise offset PLL transmitter, Digital modulator, TXDAC, RAMPDAC, and AFCDAC. The B6PLD includes state machine control through serial programming. All functions operate down to 2.67V and are housed in a 72-pin BGA package. Hence the B6PLD can form a small size transceiver handset for quad band EDGE tranceiver.

3.2 RF Part

3.2.1 Receiver Part

The B6PLD receiver supports quad band, so the front-end incorporates four LNAs and two mixers. The incoming RF signals are mixed directly down to I/Q baseband by the front-end bolck. This incorporates four LNAs/four buffers and two Gillbert Cell mixer blocks optimised for operation at 850MHz, 900MHz, 1800MHz and 1900MHz respectively. The front-end block is followed by two closely matched baseband amplifier chains. These include distributed low pass filtering, one switched gain stage and one fixed gain stage. In addition, the baseband section integrates A/D and D/A converters which provide automatic on-chip correction of DC offsets.

3.2.1.1 Baseband PGA/Low pass Filter Specifications

The baseband programmable amplifier comprises one stage with variable gain followed by a fixed gain amplifier. The overall gain control range is 36dB with 6dB Steps. The filtering is provided by a single R/C low pass filter with an on-chip capacitor followed by on-chip Chebychev low pass filters. The filters have been specified to achieve maximal group delay flatness in the pass-band combined with the required levels of suppression of interfering signals. The distribution of the gain and filtering has been designed to ensure that the receiver does not compress under blocking conditions. The final fixed gain amplifier is included to match the on-chip levels to the input dynamic range of the ADC.

3.2.1.2 DC offset auto-calibration system

B6PLD implements a system for cancelling the DC offsets in the baseband programmable gain amplifiers(PGA). This prevents a small DC offset at the input giving a large DC offset at the output, even at high gain settings. When the B6PLD receiver is performing an auto-calibration, the sequencer cancels the offsets locally around the PGA, then the Digital filter. The system includes switches to short out the signal path whilst the cancellation is occurring. The switches are opened in sequence as the calibration progresses. For PGA the A/D converter system employs a successive approximation technique and achieves 6 bit resolution. The PGA stage has an associated 6 bit current DAC which cancels the DC offset at the output. The sequencer ensures that on-chip filters have sufficient time to settle before applying correction in the next digital offset cancellation stage.

3.2.6.2 Control system and digital interface

The B6PLD is a RF transceiver IC for GSM850, DCS1800 and PCS1900 Tri band cellular system, and incorporates EDGE transceiver capability. The B6PLD has a digital interface connection to the baseband processor. This interface complies with the digital interface specification DigRF standard v112. The digital interface consists of two separate interface connections; (1) the control interface, (2) the data interface, and a system clock on/off control signal and a precise timing singal. These are realized by eight signal lines in B6PLD(Look at Fig1.1 above)

- The control interfce is used to configure the B6PLD for RX and TX operation, transfers of control

data for several built-in circuits, and for triggering the events. The control interface comprise a bidirectional 3-wire serial interface with the three signal lines CtrlData, CtrlEn and CtrlClk accessing the control registers in B6PLD by transferring the control words.

-. The data interface is used to transfer transmit modulation symbols and receive IQ-sampling data.

The data interface comprises a single serial bus with the three signal lines RxTxData, RxTxEn and SysClk. The SysClk is used for system clock to baseband.

-. The SsClkEn signal enables the SysClk output and powers the 26MHz oscillator on. When the

SysClkEn is negated, the SysClk is held low, and if the TEST1 pin is low by the default settings, the logic power supply by typical 1.8 volts to the internal core logic circuits is also switched off.

- The system components are used to manage system interactions such as interrupts, clock control, reset control, and idle management.

- The peripheral subsystem refers to all the peripherals accessible by the MPU and/or the DSP. They are all OCP- or TIPB-compliant and are connected to the OMAP3.4 platform through the traffic controller or the TIPB busses.

3.3.3 RF Interface (Digital RF Interface)

The OMAPV1030 radio interface module of OMAPV1030 device is an interface that carries the following information:

- Transmit symbols from DBB to RF IC

- Receive samples from RF IC to DBB

- Bidirectional information control

- Real-time and activation signals from DBB to RF IC

- System clock

The OMAPV1030 radio interface module of OMAPV1030 device supports two types of radio interfaces. They differ mainly in the type of data interface:

- The first interface is based on a standard six-wire scheme: three wires for transmit and three for receive.

- The second one is based on a two-wire bidirectional scheme: one wire for data in/out, and one for control receive/transmit.
