    6. CIRCUIT OPERATION (BASE UNIT) BLOCK DIAGRAM BASEBAND SECTION AND LINE INTERFACE (BASE UNIT)
  • Page 20 6.1. THE BASE-BAND SECTION 6.1.1. INTRODUCTION (SEE Fig. 17) 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.
  • Page 21 The electrically erasable PROM PQVIT2464WM6 (IC9) is used to store all the temporary operating parameters for the base (see EEPROM LAYOUT (BASE UNIT)). It uses a two-line serial data interface with the BBIC, with bi-directional data on pin 5 (TP104), and clock on pin 6 (TP3). 6.1.5.
  • Page 22 6.2. THE LINE INTERFACE SECTION (SEE BLOCK DIAGRAM Fig. 17) 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 23 a combination of components selected from R85, R86, C93, C37 and R1. The combination depends upon the CLIP requirements of the specific country - often there is no requirements for the CLIP_STATE impedance. T10 disables the CLIP signal during the off-hook condition. 6.2.5.
  • Page 24 Circuit Diagram 6.3. Speakerphone (SEE Fig. 21) The extra circuitry for the TCD715 speakerphone circuit comprises a microphone, a speaker, and a speaker amplifier IC14. However, note that the majority of the speakerphone functionality is contained within the existing BBIC IC6. This includes the switching between microphone and speaker path, echo suppression and cancelling, etc.
  • Page 25 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 26 C71 and R2 (Positive), R78, C72 and R71 (negative). 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.

    lines. 7. CIRCUIT OPERATION (HANDSET) BLOCK DIAGRAM BASEBAND SECTION (HANDSET) 7.1. THE BASE BAND SECTION 7.1.1. 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.
  • Page 28 manufacture and service to connect to an external computer. 7.1.3. FLASH ROM (SEE Fig. 24) The 1Mbit Flash PROM IC3 contains the operational firmware for the BBIC's general purpose microprocessor. It is interfaced to the BBIC using address lines A0 to A17, data lines D0 to D7, and control lines CE (Chip Enable), WE (Write Enable) and OE (Output Enable).
  • Page 29 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. The burst mode controller processes this stream performing encryption and scrambling, adding the various other fields to produce the GAP standard DECT frame, assigning to a time slot and channel etc.
  • Page 30 7.1.9. KEYBOARD (SEE Fig. 26) 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 31 7.1.11. BATTERY SUPPLY (SEE Fig. 27) 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 32 7.2. RF SECTION 7.2.1. BLOCK DIAGRAM RF SECTION (HANDSET)
  • Page 33 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. The TXDA signal is used to control the modulation of this frequency to 1.87GHz to 1.93GHz.
  • Page 34 adjustment value.". 5. Connect the frequency counter probe to TP101, or pin12 of the RF module, to measure the SYRI signal from the BBIC. 6. The clock frequency should be within 10,368,000Hz ± 10Hz. If not then enter "SETFREQ nn nn" where nn nn are the clock frequency adjustment values.
