7.1. R.F. SECTION (SEE BLOCK DIAGRAM Fig. 13)

7.2. THE BASE-BAND SECTION (SEE BLOCK DIAGRAM Fig.

14)

7.2.1. INTRODUCTION

The base-band section consists of a base-band integrated circuit (BBIC), a Flash
PROM, an EEPROM, and an AND Gate.

7.2.2. THE BASE-BAND INTEGRATED CIRCUIT (BBIC)

The PQVINSC14424 (IC101) is a CMOS device designed to handle all the audio,
signal and data processing needed in a DECT base unit. It contains a "burst
mode controller” microprocessor which takes care of DECT specific physical
layer and radio section control. It also contains two ADPCM transcoders, a low

power 14 bit codec (ADC/DAC), various other ADC´s, DAC´s and timers, a
gaussian filter for the DECT GFSK modulation method, clock and data recovery
circuits, a clock oscillator circuit, a DTMF generator (DSP), an echo suppression
circuit (DSP), and a pair of gain controllable audio amplifiers for line input and
line output and a general purpose microcontroller.
The IC101 interfaces to its external PROM (IC102) via a data/address/control
bus. It connects to the EEPROM via a serial interface, and a second serial
interface is used during manufacture and service to connect to an external
computer.

7.2.3. FLASH PROM (SEE Fig. 15)

The 1 Mbit (IC102) Flash PROM contains the operational firmware for the
microcontroller. It is interfaced to the data/address/control bus using address
lines A0 to A16, data lines D0 to D7, and chip select (pin 30), output enable (pin

32), and write (pin 7).

7.2.4. EEPROM (SEE Fig. 15)

The electrically erasable PROM PQVINM4C32L (IC103) is used to store all the
temporary operating parameters for the base (see EEPROM LAYOUT). It uses a
two-line serial data interface with the BBIC, with bi-directional data on pin 5
(TP94), and clock on pin 6 (TP93).

7.2.5. CLOCK GENERATION (SEE Fig. 15)

A single clock generator in the BBIC uses an external crystal X101 to derive all
clock frequencies used in the base. The crystal is tuned to the exact frequency
of 10.368 MHz during manufacture by feeding a DC voltage from a DAC in the
microcontroller (from pin 14 of IC101) to the varicap diode D104 (TP112).
The BBIC provide buffered clock signals RFCLK (pin 11, TP139) at 10.368 MHZ
for the Frequency Synthesizer, which is only active during the PLL lock period.
Other clock is SCLK on pin 1 (3.456MHz). The basic data rate for TRADAT and
RECDAT is 1.152 Mbits/s, which is 10.368 MHs divided by 9. The data rate for the
serial interface to the phase-lock-loop is also 1.152 Mbits/s.

Circuit Diagram

7.2.6. LOCATOR KEY (SEE Fig. 15)

The keyboard “Locator (Page)” button is connected to pin 68 (TP154) of the
IC101. When pressed the base transmits a message to the handset, which then
beeps.

7.2.7. FACTORY SERIAL PORT (SEE Fig. 15)

In order to communicate with the handset during manufacture and servicing
(using a PC) a serial data link has been provided. Serial data input/output is
provided on J102 (TP151), and a ground is provided on J103. The bi-directional
serial data line is split into two at IC101 pin 27 (input) and pin 26 (output). Data
rate is 9600 baud J103. D105provides ESD protection, and R117 and C146
provide RF de-coupling.

7.2.8. BUZZER CIRCUIT (SEE Fig. 15)

A square-wave signal from IC101 pin 41 (TP103) is used to sound the buzzer via
switching transistor T101 (TP101). Various tones and cadences are used
dependent on function. Buzzer volume is varied by changing the duty cycle of
the drive waveform. D101 provides quenching of back-emf generated when T101
turns off.

7.2.9. OFF HOOK AND CALLER LED´S (SEE Fig. 15)

When the Handset is in “Talk” mode, the Off-Hook LED D102 is switched on by
transistor T102 (on), using a control line from pin 28 of IC101 (TP106). “On the
TCD952 the caller” LED is switched via T103.

7.2.10. AUDIO PATH-RX AUDIO-LINE INPUT (SEE Fig. 16)

Audio from the Line Interface TXAF (TP123) enters the BBIC on pin 58. R111 and
C113 are to balance the line input amplifier, into the ADC part of the codec,
where it is sampled and turned into digital data. The burst mode controller then
processes this raw data (called the B-field) performing encryption and
scrambling, adding the various other fields that go together to produce the GAP
standard DECT frame, assigning to a time slot and channel etc. The data then
passes through the gaussian filter to emerge on pin 22 as TRADAT, (TP132).

7.2.11. AUDIO PATH - TX AUDIO - LINE OUTPUT (SEE Fig. 16)

Audio from the receiver RECDAT enters the BBIC on pin 20 and passes through
the clock recovery circuit. The burst mode controller separates out the B-field
data, and performs de-encryption and de-scrambling as required. It then goes to

the DAC part of the codec where data is turned back into analogue audio. The
audio signal is amplified by the gain-controlled line output amplifier, and
balanced audio is output on pin 63, and fed as RXAF (TP120) to the Line
Interface.

Circuit Diagram

7.3. THE LINE INTERFACE SECTION (SEE BLOCK

DIAGRAM Fig. 15)

7.3.1. INTRODUCTION

This section consists of the telephone line interface, bell detector, hookswitch,
pulse dialing circuits, audio circuits, DC mask & line impedance circuits, power
supplies, and battery charger circuits.

7.3.2. TELEPHONE LINE INTERFACE (SEE Fig. 17)

The telephone line is connected (via 2 or 3 jumpers selected for country of
destination) to a bridge rectifier D8. Surge suppressor SA3 protects against
excessive line voltages. Test points are TP14 (A), TP13 (B), TP21 (S) and TP15
(E). Bridge rectifier D8 provides for lines of either polarity. The output of D8 is
“Line +” (TP50) and “Line -” which is ground.

7.3.3. EARTH RECALL (SEE Fig. 17)

For countries that require Earth Recall facilities, relay RLY1 is provided to short
the E line to the A or B lines. The relay is energised when transistor T2 is
switched on by a high level on the EARTH control line (TP77) from the BB-IC
IC101. D1 will quench the large back-emf voltage that would otherwise occur
across the relay coil when T2 turns off.

7.3.4. BELL DETECTOR (SEE Fig. 17)

The AC ringing signal is detected by optocoupler IC2, using its internal diode in
conjunction with D4. DC from the line is blocked by the wall plug inside. The
other components D2, D3, and R3 reduce current and increase the circuit
impedance in line with national requirements. When ringing is detected IC2 will
turn on, and the RING line (TP76) will be dragged to a low voltage.

Circuit Diagram

7.3.5. CLIP CIRCUITS (SEE Fig. 17)

The caller ID signal is detected by IC4.

7.3.6. HOOKSWITCH (AND PULSE DIALING) (SEE Fig. 18)

T8 is the hookswitch, driven by T9. When the phone is “off-hook”, the HOOK
control signal from the BBIC will be a high logic level (+3V), and all both
transistors will be on, thus T8 will “loop” the line. The zenner diode D10
protects transistors T11 to T13 against transient line voltages.

7.3.7. PULSE DIALING (SEE Fig. 18)

During pulse dialing the hookswitch (T8, T9) is used to generate the pulses
using the HOOK control signal, which is set high during pulses. To force the line
impedance low during the “pause” intervals between dial pulses, the
PAUSE-DIAL signal turns on T11, which turns on T12 harder (increases current),
thus reducing line impedance (see 7.3.10. BATTERY CHARGER (SEE Fig. 19))

7.3.8. AUDIO CIRCUITS (SEE Fig. 18)

The line output signal from the BBIC RXAF (TP120) is amplified by T13. The
RXAF line is DC coupled to T13 thus making it work as a current limiter (typically
< 8mA). The emitter load of T13 is complex to achieved the correct frequency
response, since the line load (for UK) is also complex. The line input signal
TXAF (TP123) is taken from the junction of R41 and R70. Phase cancellation of
the line output audio occurs at this point, so that only incoming line audio
should be passed to the BBIC on TXAF.

Circuit Diagram

7.3.9. POWER SUPPLIES (SEE Fig. 19)

The AC Adaptor for the KX-TCD952PDB consists of two separate isolated DC
supplies providing a +8 V supply for the base circuitry, and a 9 V supply only for
the charger circuit. The isolation is because the main base circuitry is
connected to the telephone line, so potentially hazardous voltages may be
present, while the charger circuitry has charge contacts that could be touched
by the operator, so the two supplies must be kept separate. The 8 V supply from
the AC Adaptor is connected via J2 pin 1 (TP90) +8 V, and J2 pin 2 (TP89)
ground. The unregulated +8 V supply is fed to the first regulator.This regulator
IC7 provides a regulated output pin 2 (TP91) of +4.0 V (called +4V). The second
regulator IC6 is fed with +4V and provides the stable +3.0V supply (TP95).
During power-up this regulator generates a RESET signal (TP94) which is used
to reset the microcontroller and BBIC.

7.3.10. BATTERY CHARGER (SEE Fig. 19)

The 9 V supply from the AC Adaptor is connected via J2 pin 6 (TP82) positive,

and J2 pin 5 (TP78) negative. The constant current battery charger circuit is
made up of T14 and T15 (series pass transistor) and associated components.
Charging detector circuit T16 switches on when a charging current flows
through R64 and D11, and turns on the “Charging” LED D12. The charge
contacts are J5. Charge current flows in via J5 (negative), through T15, R63, AC
Adaptor 9 V supply, R64, D11, and out via J5 (positive).

10.1. THE BASE-BAND SECTION (SEE BLOCK DIAGRAM

Fig. 21)

10.1.1. INTRODUCTION

The base-band section consists of a base-band integrated circuit (BBIC), a Flash
PROM, an EEPROM, an LCD Display, a Microphone, an Earpiece, and power
supply/battery management circuits.

10.1.2. THE BASE-BAND INTEGRATED CIRCUIT (BBIC)

The National SC14405 BBIC (IC1) is a CMOS device designed to handle all the
audio, signal and data processing needed in a DECT handset. It contains two
microprocessors - one general purpose - while the other ìburst mode controllerî
takes care of DECT specific physical layer and radio section control.The BBIC
also contains the ADPCM transcoders, a low power 14 bit codec (ADC/DAC),
various other ADCís, DACís and timers, a UART for data communication with RF

unit, a gaussian filter for the DECT GFSK modulation method, clock and data
recovery circuits, a clock oscillator circuit, a battery management circuit, and a
pair of gaincontrollable amplifiers for the microphone and earpiece.

10.1.3. FLASH PROM (SEE Fig. 22)

The 2 Mbit Flash PROM IC2 contains the operational firmware for the BBIC’s
general purpose microprocessor. It is interfaced to the BBIC using address lines
AD0 to AD17, data lines DAB0 to DAB7, and the chip select (IC1 pin 84), read (IC1
pin 86), and write (IC1 pin 93) control lines.

Circuit Diagram

10.1.4. LCD DISPLAY, AND DISPLAY DRIVER (SEE Fig. 23)

The LCD display also receives data via a serial interface. Serial data is sent to
LCD display on pin 3 (TP70). The RS signal (pin 1, TP67) is used by the BBIC to
send either commands or data.

Fig. 23

Circuit Diagram

10.1.5. AUDIO PATH - TX AUDIO (SEE Fig. 24)

Balanced audio from the microphone (TP40 and TP41) enters the BBIC at pins
61 and 63. A balanced bias voltage for the (“electret” type) microphone is
supplied by the BBIC from pins 60 and 64 via R31 and R32. This supply is
de-coupled by R22, R27, C21, C28, and C22. RF de-coupling of the microphone
signal is provided by R27, C25, R28, C26, R24, R25, and C20. The microphone
audio signals are coupled to the BBIC via C22 and C23, which provide some
high pass filtering.
In the BBIC audio passes through the gain-controlled microphone amplifier, into
the ADC part of the codec, where it is sampled and turned into digital data. The
burst mode controller then processes this raw data (called the B-field)
performing encryption and scrambling, adding the various other fields that go
together to produce the GAP standard DECT frame, assigning to a time slot and
channel etc. The data then passes through the gaussian filter to emerge on pin
20 as TRADAT.

10.1.6. AUDIO PATH - RX AUDIO (SEE Fig. 24)

Audio from the receiver RECDAT (TP54) enters the BBIC on pin 18 and passes
through the clock recovery circuit. The burst mode controller separates out the
B-field data, and performs de-encryption and de-scrambling as required. It then

goes to the DAC part of the codec where data is turned back into analogue
audio. The audio signal is amplified by the gain-controlled earpiece amplifier,
and balanced audio is output on pins 65 and 66, and fed to the earpiece (TP31
and TP32). The leads feeding the earpiece are RF de-coupled by C15 to R22,
C17, C16, R23, and C18. C19 provides low pass filtering.

Fig. 24

Circuit Diagram

10.1.7. CLOCK GENERATION (SEE Fig. 25)

A single clock generator in the BBIC uses an external crystal X1 to derive all
clock frequencies used in the handset. The crystal is tuned to the exact
frequency of 10.368 MHz during manufacture by feeding a DC voltage from an
internal DAC (from pin 12) to the varicap diode D12 (TP25). The RFCLK output
(pin 10, TP56) is a buffered clock signal at 10.368 MHz for the Frequency
Synthesizer, that is only active during the PLL lock period (see section 1.3). The
basic data rate for TX-DATA and RX-DATA is 1.152 Mbits/s, which is divided by

9. The data rate for the serial interface to the phase-lock-loop is also 1.152

Mbits/s.

10.1.8. KEYBOARD (SEE Fig. 25)

The keyboard “On” button is connected directly to pin 41 of the BBIC (TP10).
When pressed it turns the handset on and off (must be held for off). All other
keys are connected in a row/column matrix. They are scanned in six rows using
scan pulses (only active when keys are pressed) from IC1 pins 28 to 33. The four
key matrix columns are input to the BBIC on pins 31 to 34.

Fig. 25

Circuit Diagram

10.1.9. FACTORY SERIAL PORT (SEE Fig. 21)

In order to communicate with the handset during manufacture and servicing
(using a PC) a serial data link has been provided. Serial data input/output is
provided on J6 (TP65), and a ground is provided on J7. The bi-directional serial
data line is split into two at IC1 pin 27 (input) and pin 26 (output). Data rate is
9600 baud or 115.2 kBaud. D13 provides ESD protection, and R37 and C56
provide RF de-coupling.

10.1.10. BUZZER CIRCUIT (SEE Fig. 26)

A square-wave signal from IC1 pin 45 is used to sound the buzzer via switching
transistor T5 (TP22). Various tones and cadences are used dependent on
function. Buzzer volume is varied by changing the duty cycle of the drive
waveform. D11 provides quenching of back-emf generated when T5 turns off.

10.1.11. BATTERY SUPPLY (SEE Fig. 26)

The three cell NiCd/NiMH rechargeable battery supplies the handset via 2A fuse
(actually a coil), and is de-coupled by C3 and C4. It directly supplies T3 in the
baseband section, and also the Tx PA in the RF Section. It also supplies IC1
(de-coupled by C9), and most of the RF Section (VCC-OC) (decupled by R35 and
C47, C48 and VCC-PA).

10.1.12. MAIN 3V REGULATOR (SEE Fig. 26)

The BBIC measures the battery voltage on pins 58 using an internal ADC. If the
battery voltage is below 3.36 V, TC3 is switched to power off mode. R7 and C5
provide a reset pulse (TP84) used for resetting the BBIC when power on. The +3
V supply (TP10) is fed to the BBIC, Flash PROM, EEPROM, and Display Driver.

10.1.13. BATTERY CHARGING CIRCUIT (SEE Fig. 26)

The charge circuit is designed to operate with a constant current charger in the
base. L1, L2, D2 and D4 protect against electro-static discharge (ESD). The
charging current from the base is turned on and off by T1 using a control signal
from the BBIC (pin 39, TP6) via T2. R3 provides initial current in the event of a
totally flat battery, and D6 protects against the high voltage present on the
charge contacts if there is no battery in the handset. R4 and R5 provide a signal
for the BBIC to detect (pin 40) that the handset had been placed on the base
charger. If the handset is off, it will be switched on, and charging will start.
