Functional description

Power distribution and control signals
The following block diagram describes the distribution of power supplies within DL2.
Battery voltage VB is fed directly to the illumination LEDS (CMT keymat and CMT display)
The regulated band supply VBB generated on the BL8 module supplies the CMT display, control logic and PDA display supply.
A power switch is used to remove the voltage supply from the control logic and PDA display when the display is turned off.

DL2 Circuit Description

The module is connected via a 50 way FPC to the BL8 system logic. The module includes following main blocks:
– CMT keyboard geometries. – Switches for PDA soft keyboard – Backlight LEDs for CMT keypad and CMT LCD illumination. – CMT LCD. – PDA LCD module. – PDA LCD backlight circuit. – PDA LCD power circuit. – PDA LCD interface control logic.
– Hinge flex connector. – Antenna connector and ground plane.
Keypad scanning.
There is 26 keys located in DL2 module. 6 PDA soft keys are located inside the lid and 20 CMT keys on the outer side. All these keys are in the same keyboard matrix as the QWERTY–keypad in the UL8 module.
Col(0–4) are used as column lines in keypad. Row(0–4 and 6) are used as row lines.
When a key is pressed the MCU gets an interrupt from a row and starts scan­ning. One column at a time is written low and rows are used to read which key is pressed.
CMT keypad and CMT LCD backlight
The CMT keypad and CMT display are illuminated with LEDs. Each LED is driven by a separate drive transistor.
LEDs for CMT display are driven with appoximately 5mA each. LEDs for CMT keymat illumination are driven with approximately 2.5mA each.
CMT LCD
Mechanical structure
LCD includes the frame, LCD cell with driver chip, reflector, adhesive tapes, and lightguide. The LCD is electrically connected to the UL2 PWB with a FPC and board–to–board connector.

The frame includes clips to mechanically attach the display to the UL2 PWB and also keep LCD cell and lightguide in place.

CCFL
The control circuit generates a square wave input to the piezo driver circuit. This signal is maintained at the resonant frequency of the piezo transformer.
The driver is based around 2 FETs in Push–pull configuration. There is a single coil between the FETs and the piezo transformer.
Both FETs are turned off while the CCFL is off during dimming (BACKPWM low).

The flyback regulator generates a negative bias voltage (Nominally –12V) from the battery voltage. The output of the flyback generator is temperature compen­sated and adjusted under software control.
The control ASIC handles the refresh of data to the PDA display panel and the generation of synchronisation signals for the swing mode regulator.
Antenna connectors and ground plane
The RF–signal from the external antenna connector/switch on BL8 is fed to the antenna via a coaxial cable that is led through the hinge. The signal is fed to the antenna through a coaxial connector and an antenna clip which are placed on the UL2 PWB.
The UL2 PWB includes the separate ground area that is required by the anten­na.

QWERTY Keyboard Module UL8

General

UL8 is the combined QWERTY keypad/flex connection module. The base flex is single–sided, so all the components are on the same side of the flex.
Approximate component placement is shown below:

AF8 PWB

AF8 is a small additional PWB to achieve ”bulls eye” shaped pads for the ear­piece and connection for the battery removal switch. (Check that the RAE-3 software supports the battery removal switch feature.)
The approximate shape of AF8 is shown below. One 22pF SMD capacitor is assembled to the AF8.
