INTEGRATED CIRCUITS DATA SHEET TEA1069; TEA1069A Versatile speech/dialler/ringer with music-on-hold Product specification Supersedes data of 1996 Dec 10 File under Integrated Circuits, IC03 1998 Jan 08 Philips Semiconductors Product specification Versatile speech/dialler/ringer with music-on-hold FEATURES Speech part • Voltage regulator with adjustable static resistance • Low DC line voltage; operates down to 1.6 V (excluding polarity guard) • Supply for dialler part and peripherals (not stabilized) • Symmetrical high-impedance inputs (64 kΩ) for dynamic, magnetic, or piezoelectric microphones • Asymmetrical high-impedance input (32 kΩ) for electret microphones • Asymmetrical earpiece output for dynamic, magnetic, or piezoelectric earpieces • Internal mute to disable speech during dialling • Confidence tone during DTMF dialling • Line-loss compensation (line-current dependent) for microphone and earpiece amplifiers • Gain-control curve adaptable to the exchange supply. Dialler part • Pulse/DTMF and mixed mode dialling • Last Number Redial (LNR), up to 32 digits • 13 repertory numbers (3 direct and 10 indirect) or 10 repertory numbers (10 direct), up to 32 digits, with a maximum of 224 digits in total • Repertory and redial memory integrity check (memory contents check) • Notepad memory function • Flash and earth register recall • Dial mode output • Access pause generation and termination • Function keys for: store, memory recall, register recall, LNR, pause, hold, mute, hook • Keytone generation • Hands-free control • Volume control in hands-free mode (VOL+/VOL−) • Hold function • Mute function • Music-on-hold • Diode options: – DTMF tone burst/pause time – make/break ratio – access pause time TEA1069; TEA1069A – pulse or DTMF mode selection – register recall (earth and flash times) – keyboard layout selection – selection for german requirements – hold/mute mode selection. Ringer part • Ringer input frequency discrimination • Ringer melody generation (3-tone) • Ringer melody selection/volume control via keyboard • Diode option: ringer frequency selection. GENERAL DESCRIPTION The TEA1069 and TEA1069A contain all the functions needed to build a highly featured, high-performance fully electronic telephone set. The device incorporates a speech/transmission part, a dialler part and a ringer part. By offering a wide range of possible adaptations for each part, the TEA1069 and TEA1069A application can be easily adapted to meet different requirements. The TEA1069A offers some different timings and diode options compared to the TEA1069. Where pin numbers are mentioned in this data sheet we refer to the TEA1069N, unless otherwise indicated. Speech part The speech/transmission part performs all speech and line interface functions required in electronic sets. It operates at line voltages down to 1.6 V DC to facilitate the use of more telephones connected in parallel. Dialler part The dialler part offers a 32-digit Last Number Redial (LNR) and 13 memories. Hands-free control is included allowing the TEA1069 and TEA1069A to be used not only in basic telephones, but also in feature phones offering hands-free dialling via the TEA1083 call-progress monitor IC and/or full hands-free operation via the TEA1093 hands-free IC. The hold function allows the user to suspend the conversation and resume the call either on the same phone or on a parallel phone. Additionally through the music-on-hold function a melody is transmitted while the set is put on hold. The keytones provide in a buzzer an audible feedback of a valid key pressed. 1998 Jan 08 2 Philips Semiconductors Product specification Versatile speech/dialler/ringer with music-on-hold Ringer part TEA1069; TEA1069A The ringer part offers a discriminator input which enables the tone output as soon as a valid ring frequency is detected. It offers a melody based on 3 tones with programmable melody and volume via keyboard.
