Overview
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) • ...
