TDA9813T TDA9813T VIF-PLL With QSS-IF And Dual FM-PLL Demodulator

The TEA1069 and TEA1069A integrate all necessary functions to create a fully electronic telephone set with advanced features and high performance. This device includes components for speech transmission, dialing, and ringing. The TEA1069 and TEA1069A can be easily customized to meet various requirements. The TEA1069A includes different timing and diode options compared to the TEA1069. Unless stated otherwise, pin numbers refer to the TEA1069N model. The speech transmission component handles all necessary speech and line interface functions for electronic telephones, operating at line voltages as low as 1.6 V DC, which allows for multiple telephones to be connected in parallel. The dialing component features a 32-digit Last Number Redial (LNR) and 13 memory slots. It supports hands-free control, enabling the TEA1069 and TEA1069A to function in basic telephones as well as feature phones that provide hands-free dialing through the TEA1083 call-progress monitor IC and/or full hands-free operation via the TEA1093 hands-free IC. The hold function allows users to pause a conversation and resume it on the same phone or a parallel phone. Additionally, the music-on-hold feature transmits a melody while the call is on hold. Key tones provide audible feedback through a buzzer for valid key presses.

The TEA1069 and TEA1069A are designed as versatile solutions for modern telecommunication needs, facilitating the development of both standard and advanced telephone systems. The speech/transmission section is critical for ensuring clear communication, handling both incoming and outgoing signals effectively. Its capability to operate at low line voltages enhances flexibility in system design, allowing multiple devices to share the same line without compromising performance.

The dialing section's Last Number Redial feature is particularly useful in enhancing user convenience, while the memory slots allow quick access to frequently dialed numbers, thereby streamlining the calling process. The inclusion of hands-free functionality broadens the applicability of these devices, making them suitable for environments where users may require the ability to multitask during calls.

The hold feature, coupled with the music-on-hold functionality, adds a layer of sophistication to the user experience, making it more enjoyable and professional. The audible feedback provided by key tones serves as an essential user interface element, confirming user inputs and enhancing the overall usability of the device.

The TEA1069 and TEA1069A are therefore well-equipped to meet the demands of contemporary communication systems, providing a robust platform for the development of feature-rich, user-friendly telephone solutions.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 me

et 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 partThe 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. 🔗 External reference
