UIF modules DU4, DL4 & GU3

General

Three modules are described in this document. They are similar – the only dif-

ference is the keyboard layout and an amount of LEDs. The three modules are

used in the different US TDMA (NHC–1 and NHC–4) phones as shown in fol-

lowing picture:

Hierarchy of design

There is a high degree of commonality between these designs.

Technically there are two schematics.

The difference between the two PCB layouts is only

LEDs (and one less LED on the Style 1 version). The DU4 layout has 20 main

keys, 2 volume keys at the side of the flex and a power key in the upper right

corner of the flex. DL4 flexis have 20 main keys in a slightly different layout and

the volume/power keys combined on one assembly.

The GU3 has one LED less than DU4. Volume and power keys are as in DU4.

Circuit description

LED drivers

The keyboard illumination is achieved by using four transistors wired as simple constant current sinks. Each transistor supplies four leds. The bases of the six transistor are all wired together and supplied by emitter follower V40. The led current is fixed by the values of (R44 to R47 inclusive) and the ratio of R59 to R57.

Note that on DL4 flexi, a 18

led (V38) is driven from an additional transistor.

The display illumination operates in a similar way to the keyboard drivers, but only two transistors are used to drive eight leds. The current in this case is defined by the value of R42 and R43 and the ratio of R60 to R61.

Call indicator

The Call LED is fed from a simple emitter follower.

Buzzer driver

The buzzer driver circuit consists of four transistor switches wired in parallel. The buzzer takes relatively large peak currents and four switches are used to minimise temperature rise in the driver during ringing. All four are driven from a single PNP– transistor switch which acts as a buffer for a CMOS output signal applied at BUZZER.

The diode V37 prevents damage to the transistors when they switch off, absorbing the stored energy in the buzzer inductance and suppressing large positive going spikes on the transistor collectors.

Audio circuitry

The audio circuitry comprises a switched analogue supply rail (Vx). The switching is used to avoid wasting current when the phone is in standby.

The earpiece is routed directly to connector X4.

UIF MODULES DU4, DL4 & GU3

NHC–1/4

VA2 is an analogue rail supplied by the PSL+ chip on the system board. It is present whenever the battery is connected and is 4.65 V in magnitude. V2 is wired as a switch for VA2, controlled by the microphone enable line [MIC_EN], in this case a CMOS output from the processor.

V9 and its associated components act as a filter to reduce any noise on the VA2 line, R29 and C13/C14 acting as a lowpass filter with a –3 dB point of about 179 Hz. The filter feeds a smooth dc voltage to the base of emitter follower V9. Its emitter provides the clean analogue supply for the transistor amplifiers. The microphone is connected to two equal value connectors, one of which connects the positive mic terminal to Vx, the other connects the negative terminal to GND. The signal is capacitively coupled to the MICN and MICP terminals of X4 via C26 and C27.

RF suppression

Small value capacitors are fitted at critical points in the circuit to try to avoid problems with RF interference. One each is placed directly across each microphone (C15). V9 has a cap to ground from each of its three terminals (C20, C21, C22) and V2 a cap from its base drive pin to ground (C19).

Display driver

Only the dc bias circuitry will be described here, the method of control of the display being outlined elsewhere. Also refer to Display Module Spec if necessary. The module contains an oscillator to generate a negative rail required for operation. The oscillator frequency is fixed by the resistance from pins 2 to 3 of X1, with the values of R6 and R16 shown, the frequency should be within 180 kHz to 370 kHz. The negative going pulses appear at pin 9 of X1 where they are smoothed by C1 to give a voltage which is nominally equal but opposite to VL1.

For correct operation of the display, dc voltages between –VL1 and VL1 need to be generated and fed back to the driver chip, at pins 4 to 8 inclusive (of X1). The exact voltages depend on the relative values of the resistors R21, R37, R38, R39, R40 and R27, R33. R1 is a thermistor which provides temperature compensation for the display. To maintain consistent contrast over temperature, these derived voltages need to be altered slightly, R1 provides this function.
