SANYO LA8519M Datasheet

Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft’s control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO products described or contained herein.

Overview

The LA8519M is a cordless telephone base unit IC that provides I/O switching, voice signal processing, and other functions. It integrates, on a single chip, crosspoint switch, power amplifier, electronic volume and tone control, microphone amplifier, speech network, and other functions.

Functions

• Speech network block — Impedance matching, 2-wire/4-wire converter,

line driver, BN circuit network switching circuit, transmitter amplifier, BTL receiver amplifier, DTMF input, key tone input, receiver volume level switching, and power supply switching circuit.

• Audio signal-processing block — Power amplifier, electronic volume and tone

control, preamplifier with ALC, voice level detection (VOX), beep tone input, ring tone (OSC) input, ring tone level switching, line volume level switching, microphone amplifier, crosspoint switch (10 × 9 point equivalent), and serial interface.

Features

• Allows switching between two anti-sidetone networks (near terminal/far terminal) depending on the line current, and thus achieves excellent sidetone characteristics over a wide range of line currents.

• Built-in transmitter/receiver amplifier driver power supply switching circuit allows communication using extension without power from the telephone network.

• The receiver amplifier supports both ceramic receivers (BTL) and dynamic receiver (single).

• Built-in power amplifier (load: 8 to 32 Ω): VCC= 5 V, RL= 8 Ω, Pomax = 200 mW

• The power amplifier signal path includes an electronic volume control (7 steps of about 3.8 dB each)

• Includes a 10-input/9-output crosspoint switch that provides mixing functions for easy implementation of systems that support a diverse range of signal path switching functions.

DATA

A6 A5 A4 A3 A2 A1 A0 D

A6 to A0 ⇒ Sets the address of the crosspoint switch or control switch (hexadecimal ⇒ binary number) D ⇒ Sets the on/off state of the crosspoint switch or control switch.

(The switch is set to the on state when D is 1, and to the off state when 0.)

* With address 3D set to the on state, SW1 is set to enable the transmitter amplifier output (pin 42) and SW4 is set to enable either the receiver amplifier

output (pin 55) or the KT (pin 39) signal. If a voltage is not supplied to V

CC

(pin 17) (i.e. the power off state), SW1 and SW4 are set to the same states

as when address 3D is set to the on state.

** For addresses 00 and 40 to 47, the data D may be either 0 or 1.

Notes: 1. The receiver attenuator (R-ATT) is set to –6 dB at power on or after a reset (pin 33 set to low, or address 00 accessed).

2. The line attenuator (L-ATT) is set to 0 dB at power on or after a reset (pin 33 set to low, or address 00 accessed).

3. The oscillator attenuator (OSC-ATT) is set to –16 dB at power on or after a reset (pin 33 set to low, or address 00 accessed).

4. The electronic volume control is set to 0 dB at power on or after a reset (pin 33 set to low, or address 00 accessed).

5. Addresses are expressed as hexadecimal numbers.

6. Since the LA8519M includes a power on reset function, all the crosspoint and control switches are reset to their default states when external power (pin 17: V

CC

) is applied.

7. Switches SW2 and SW3 in the block diagram are controlled by the MUTE pin (pin 35). The table lists the signals enabled by this pin.
