RH-10 System Module CCS Technical Documentation Useful Terms AMPS (Advanced Mobile Phone Service): The term used by AT&T's Bell Laboratories (prior to the break-up of the Bell System in 1984) to refer to its cellular technology. The AMPS standard has been the foundation for the industry in the United States, although it has been slightly modified in recent years. 'AMPS-compatible' means equipment designed to work with most cellular telephones.
RH-10 System Module CCS Technical Documentation Encryption: The transformation of data, for the purpose of privacy, into an unreadable format until reformatted with a decryption key. 'Public key' encryption utilizes the RSA (which stands for its developers, Rivest, Shamir, and Adleman) encryption key. PGP, or Pretty Good Privacy, is a cryptography program for computer data, e-mail, and voice conversation. ESN (Electronic Serial Number): The unique number assigned to a wireless phone by the manufacturer.
RH-10 System Module CCS Technical Documentation IOTA (Internet Over The Air): Specification for Internet based Over The Air handset configuration management. MIN (Mobile Identification Number): A number assigned by the wireless carrier to a customer's phone. The MIN is meant to be changeable, since the phone could change hands or a customer could move to another city. See also ESN, IMSI, TMSI.
RH-10 System Module CCS Technical Documentation wireless systems. The data is packetized and spread over a range of bandwidth. Standby Time: The amount of time a fully charged wireless portable or transportable phone can be on (though not in a call) before the phone's battery will lose power. See also Talk Time. Synchronization: Also known as 'replication,' it is the process of uploading and downloading information from two or more databases, so that each is identical.

This device is designed to be programmed in-system with the standard system 1.8-volt Vcc supply. A 12.0 volt Vpp is not required for program or erase operations, although an acceleration pin is available if faster write performance is required.

RH-10 System Module CCS Technical Documentation Power Key All signals for keyboard are coming from UPP ASIC except pwr key signal which is connected directly to UEM. When the pwr key is pressed, a switch connects the UEM PWONX to GND and creates an interrupt. Keys Other keys are detected so that when a key is pressed down, the metal dome connects one S-line and one R-line of UPP to GND and creates an interrupt for SW.
RH-10 System Module CCS Technical Documentation Vibra Introduction Vibra is located on the D-cover and is connected by spring connectors on the PWB. It is located in the left bottom side of the engine. Interfaces Vibra is controlled by pwm signal VIBRA from UEM. This signal allows control of both frequency and pulse width of signal. Pulse width is used to control current when battery voltage changes. Frequency control searches for optimum frequency to ensure silent and efficient vibrating.
RH-10 System Module CCS Technical Documentation Buzzer Introduction The functioning principle for the buzzer is magnetic. The diaphragm of the buzzer is made of magnetic material and is located in a magnetic field created by a permanent magnet. The winding is not attached to the diaphragm as is the case with the speaker. The winding is located in the magnetic circuit so that it can alter the magnetic field of the permanent magnet, thus changing the magnetic force affecting the diaphragm.

RH-10 System Module CCS Technical Documentation Accessories Interface When the MCU-SW receives a headset-interrupt, generated by the switch in the headset-connector, it will start the accessory-detection sequence. At first it will measure the voltage at XMICP-pin (divided in half by two resistors) via EAD AD-converter in CCONT. If it detects a voltage, it will start the sequence for the active accessory detection. If there is no active voltage detected at XMICP, AUXOUT-pin of COBBA_D is switched to 1.
RH-10 System Module CCS Technical Documentation Interface The F100 fuse protects the phone from too high currents (e.g., when broken or pirate chargers are used). L100 protects the engine from RF noises, which may occur in the charging cable. V100 protects the UEM ASIC from reverse polarity charging voltage and from too high charging voltage. C105 is also used for ESD and EMC protection. Spark gaps are used for ESD protection right after the charger plug.

RH-10 System Module CCS Technical Documentation areas. Target is that any ESD pulse faces ground area when entering the phone (e.g., between mechanics covers). All holes in PWB are grounded and plated through holes (with the exception of LED holes, which cannot be grounded). LCD ESD protection for LCD is implemented by connecting the metal frame of LCD to gnd. Connection is only on one side, at the top of the LCD, and that is not the best solution.

RH-10 System Module CCS Technical Documentation Transmitter Figure 2: TX block diagram The transmit chain up to the RF driver stage is integrated into one transmit-integrated circuit called Robin, with external power amplifiers (PA). The channel bandwidth is 50 kHz. All data transmitted on the channel is convolutionally encoded and block-interleaved. Modulation is 64-ary orthogonal (RC1 and RC2) and direct sequence spread by a quadrature pair of PN sequences at a fixed chip rate.
RH-10 System Module CCS Technical Documentation to vary the PA gain and PA bias current. The variable gain technique reduces PA current consumption and improves the signal-to-noise ratio at low output power levels. The precision bias current (and gain) control is achieved by varying the PA reference current with a PDM control voltage. The PA module also incorporates a “Boost” mode that can be turned on for signal modulations exhibiting Peak to Average (PAR) ratios greater than 4.0.

The synthesizer has an internal VCO with an external resonator. The VCO operates at two times the CELL IF frequencies. A band-switch signal, VCO_Band, is used to shift the center frequency of the external resonator.
