  • Page 8: Using The Belt Clip

    - The telephone will not work during a power failure. We therefore recommend you use a standard telephone and automatic change- over switch to connect this Digital Cordless Phone to the line. Your Panasonic sales shop can offer you more information about connection possibilities. 4.2. Using the Belt Clip You can hang the handset on your belt or pocket using the belt clip.

  • Page 18 The base-band section consists of a base-band integrated circuit (BBIC), a Flash PROM and an EEPROM. 6.1.2. THE BASE-BAND INTEGRATED CIRCUIT (BBIC) The CICB00001367 (PMB5737 : IC6) 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" which takes care of DECT specific physical layer and radio section control.
  • Page 19 through using the SCL terminal (J103). A ground terminal is provided by J104. The serial port terminals J100 to J104 are connected to by means of test probe pads on the ground plane side of the pcb. 6.1.8. AUDIO PATH-RX AUDIO-LINE INPUT (SEE Fig.
  • Page 20 6.2. THE LINE INTERFACE SECTION (SEE BLOCK DIAGRAM Fig. 6.2.1. INTRODUCTION This section consists of the telephone line interface, bell detector, charge-pulse detector, hook switch, pulse dialing circuits, audio circuits, DC mask & line impedance circuits, power supplies, and battery charger circuits. 6.2.2.
  • Page 21 the CLIP_STATE impedance. T10 disables the CLIP signal during the off-hook condition. 6.2.5. HOOKSWITCH (SEE Fig. 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 (+2.7V), and both transistors will be on, thus T8 will “loop” the line.
  • Page 22 6.2.9. POWER SUPPLIES (SEE Fig. The AC adaptor for the KX-TCD735 provides unregulated DC through J2 for the handset charge terminal, 6V regulator (IC1) the 3.8V regulator (IC7) and the Relay coil (RL1) where fitted. The 3.8V supply from IC7 is used for the RF module, and is further reduced by IC11 to 2.7V for the BBIC supply.
  • Page 23 6.3.1. Path from Telephone Line to Speaker Audio from the telephone line passes via the normal signal path of J1 tel-line connector (TP26 and TP40), D8 bridge rectifier, T8 hookswitch (TP50), and R41, to BBIC IC6 pin 133. In the BBIC it is converted from an analogue audio signal into digital data in the BBIC's internal codec.

  • Page 24: Circuit Operation (Handset)

    The analogue signal is converted into a digital signal in the BBIC IC6 pin 119 and 122. The speakerphone switching and echo suppression functions are contained within the BBIC. The digital data is converted again into an analogue signal in the BBIC's internal codec. The analogue signal is fed from IC6 pin126, via T13 audio amplifier, T8 hookswitch (TP50), D8 bridge rectifier, to J1 tel.
  • Page 25 7.1.2. THE BASE-BAND INTEGRATED CIRCUIT (BBIC) The PMB6723 (IC1) is a CMOS device designed to handle all the audio, signal and data processing needed in a DECT handset. It contains a "burst mode controller" which takes care of DECT specific physical layer and radio section control. It also contains an ADPCM codec filter used for speech encoding and decoding in the DSP section, a general purpose microcontroller, various other ADC's, DAC's, timers and power control circuitry.
  • Page 26 7.1.6. AUDIO PATH - TX AUDIO (SEE Fig. The audio signal from the microphone (TP23) enters the BBIC at pin 44. RF decoupling and signal conditioning are provided by C17, R21, C14 and C25. In the BBIC the signal passes through the analogue section where it is amplified and converted to a digital audio stream signal.
  • Page 27 Fig. 25 7.1.9. KEYBOARD (SEE Fig. The keyboard “On” button is connected directly to pin 33 and 28 of the BBIC. When pressed it turns the handset on and off. All other keys are connected in a row/column matrix. They are scanned in five rows using scan pulses (only active when keys are pressed) from IC1 pins 15 to 19.
  • Page 28 7.1.11. BATTERY SUPPLY (SEE Fig. A switch mode boost converter is used to provide a 3.8V supply from the battery. This supply is sensed by the BBIC through pin 26 (TP14) so that the switching rate can be controlled by a FET (T3) driven from pin 24 (TP13).
  • Page 29 7.2. RF SECTION 7.2.1. BLOCK DIAGRAM RF SECTION (HANDSET) Fig. 28 The RF section consists of two main components: The PMB6610 transceiver and the PMB6618 power amp. In the transceiver the 10.368MHz clock signal SYCL is multiplied to around 1.9GHz using PLL (Phase Locked Loop) control.
