NPW-1 System Module PAMS Technical Documentation Transceiver NPW-1 Introduction The NPW-1 is a dual band transceiver unit designed for TDMA800/1900 networks. The transceiver consists of the engine module (WS8) and the various assembly parts. The transceiver has a full graphic display and the user interface is based on a jack style UI with two soft keys. An internal antenna is used in the phone, and there is no connection to an external antenna.
PAMS Technical Documentation NPW-1 System Module Operational Modes Below is a list of the phone’s different operational modes: 1 Power Off mode 2 Normal Mode (Power controlled by cellular SW, includes various Active and Idle states): • Analog Modes (800 MHz only): •Analog Control Channel, ACCH •Analog Voice Channel, AVCH • Digital Modes (800 and 1900 MHz): •Control Channel, DCCH •Digital Voice Channel, DTCH (Digital Traffic Channel) •Digital Data Channel, DDCH Both the analog and digital modes have diff
NPW-1 System Module • PAMS Technical Documentation storage temperature range: -40 to + 85 ×C All of the EIA/TIA-136-270A requirements are not exactly specified over the temperature range. For example, the RX sensitivity requirement is 3dB lower over the –30 - +60 °C range.
NPW-1 System Module PAMS Technical Documentation Engine Module Baseband Module The core part of the transceiver’s baseband (see the figure below) consists of 2 ASICs, the UEM and UPP, and flash memory. The following sections illustrate and explain these parts in detail. Figure 2: System Block Diagram (simple) PA supply RF Supplies BATTERY SAFARI RFIC CTRL RFCLK 19.
NPW-1 System Module PAMS Technical Documentation Regulators The UEM has six regulators for baseband power supplies and seven regulators for RF power supplies. The VR1 regulator has two outputs: (1) VR1a and (2) VR1b. In addition to these, there are two current generators - IPA1 and IPA2 - for biasing purposes. A bypass capacitor (1uF) is required for each regulator output to ensure stability. Reference voltages for regulators require external 1uF capacitors.
PAMS Technical Documentation NPW-1 System Module The VR1 regulator uses two LDOs and a charge pump. The charge pump requires one external 1uF capacitor in the Vpump pin and a 220nF flying capacitor between the CCP and CCN pins. In practice, the 220nF flying capacitor is formed by 2 x 100nF capacitors that are parallel to each other. The VR1 regulator is used by the Safari RF ASIC.
NPW-1 System Module PAMS Technical Documentation Audio Codec The baseband supports two external microphone input areas and one external earphone output. The input can be taken from an internal microphone, a headset microphone or from an external microphone signal source through a headset connector. The output for the internal earpiece is a dual-ended type output, and the differential output is capable of driving 4Vpp to the earpiece with a 60 dB minimum signal as the total distortion ratio.
PAMS Technical Documentation 2 NPW-1 System Module The NMP custom cellular logic functions are known as the Body. The Body contains interfaces and functions needed for interfacing other baseband and RF parts. The body consists of, for example, the following sub-blocks: (1) MFI, (2) SCU, (3) CTSI, (4) RxModem, (5) AccIF, (6) UIF, (7) Coder, (8) BodyIF, (9) PUP. Flash Memory Introduction The NPW-1 transceiver uses a 32 Mbit flash as its external memory.
NPW-1 System Module PAMS Technical Documentation User Interface Hardware LCD Introduction NPW-1 uses a black & white GD46 84x48 full dot matrix graphical display. There are two suppliers for this LCD: Seiko Epson and Philips. The LCD module includes the LCD glass, the LCD COG-driver, an elastomer connector and a metal frame. The LCD module is included in the lightguide assembly module. Interface The LCD is controlled by the UI SW and the control signals are from the UPP asic.
NPW-1 System Module PAMS Technical Documentation 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 the UPP to the GND and creates an interrupt for the SW. This kind of detection is also known as metaldome detection. The matrix of how lines are connected and which lines are used for different keys is described in the Table 1. The Sline S0 and R-line R5 are not used at all.
NPW-1 System Module PAMS Technical Documentation Vibra Introduction The vibra is located on the D-cover and is connected by spring connectors on the bottom left-hand side of the engine. The vibra motor is supplied by Namiki. Interfaces The vibra is controlled by the PWM signal VIBRA from the UEM. With this signal, it is possible to control both the frequency and pulse width of the signal. The pulse width is used to control the current when the battery voltage changes.
PAMS Technical Documentation NPW-1 System Module Audio HW Earpiece Introduction The Philips Speaker System 13mm speaker capsule is used in NPW-1. The speaker is a dynamic one. It is very sensitive and capable of producing relatively high sound pressure also at low frequencies. The speaker capsule and the mechanics around it together make the earpiece. Microphone Introduction The microphone is an electret microphone with an omnidirectional polar pattern.
NPW-1 System Module PAMS Technical Documentation Battery Phone Battery Introduction The BMC-2 battery (Ni-MH 640mAh) is be used in the NPW-1 transceiver by default. It is also possible to use the BMC-3 (Ni-MH 900mAh) and BLC-2 (Li-ion 850mA) batteries. Interface The battery block contains NTC and BSI resistors for temperature measurement and battery identification. The BSI fixed resistor value indicates the chemistry and default capacity of a battery. The NTC-resistor measures the battery temperature.

This makes the phone easier to assemble in production and the connection between the battery and the PWB is more reliable. The battery connector is manufactured by Molex.

NPW-1 System Module PAMS Technical Documentation Accessories Interface System connector Introduction NPW-1 uses accessories via a system connector. Interface The interface is supported by fully differential 4-wire (XMICN, XMICP, XEARN and XEARP) accessories. NPW-1 supports the HDC-5 headset, LPS-3 loopset and the PPH-1 car kit.

The IR module is located at the top of the engine side, next to the Power switch. The IR module manufacturer for the NPW-1 transceiver is Vishay.
PAMS Technical Documentation NPW-1 System Module Interface The fuse F100 protects the phone from too high currents, for example, 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 voltages. C106 is also used for ESD and EMC protection. Spark gaps right after the charger plug are used for ESD protection.
NPW-1 System Module PAMS Technical Documentation Test Interfaces Production Test Pattern The interface for NPW-1 production testing is a 5pin pad layout in the BB area (see the figure below). The production tester connects to these pads by using spring connectors. The interface includes the MBUS, FBUSRX, FBUSTX, VPP and GND signals. The pad size is 1.7mm. The same pads are used also for AS test equipment, such as the module jig and the service cable. Figure 9: Top View of Production Test Pattern 2.
PAMS Technical Documentation NPW-1 System Module EMC General The EMC performance of NPW-1’s baseband is improved by using a shield to cover the main components of the BB, such as the UEM, UPP and Flash. The UEM has internal protection against a ±8kV ESD pulse. The BB-shield is soldered to the PWB and it also increases the rigidity of the PWB in the BB area, thus improving the phone’s reliability. The shield also improves the thermal dissipation by spreading the heat more widely.
