Switch/Voice Signal-Processing Cordless Telephones
Overview
LA8519M cordless telephone base unit that provides switching, voice signal processing, other functions. integrates, single chip, crosspoint switch, power amplifier, electronic volume tone control, microphone amplifier, speech network, other functions.
Features
Allows switching between anti-sidetone networks (near terminal/far terminal) depending line current, thus achieves excellent sidetone characteristics over wide range line currents. Built-in transmitter/receiver amplifier driver power supply switching circuit allows communication using extension without power from telephone network. receiver amplifier supports both ceramic receivers (BTL) dynamic receiver (single). Built-in power amplifier (load: Pomax power amplifier signal path includes electronic volume control steps about each) Includes 10-input/9-output crosspoint switch that provides mixing functions easy implementation systems that support diverse range signal path switching functions.
Functions
Speech network block Impedance matching, 2-wire/4-wire converter, line driver, circuit network switching circuit, transmitter amplifier, receiver amplifier, DTMF input, tone input, receiver volume level switching, power supply switching circuit. Audio signal-processing block Power amplifier, electronic volume 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 point equivalent), serial interface.

Power amplifier phase compensation capacitors external components, capacitors between (output) (ground) between (VCC) power amplifier phase compensation capacitors. these components separated from their pins layout, their phase compensation effect reduced high-frequency oscillation occur. therefore strongly recommend using layout which capacitors located close possible their respective pins. particular, which connected ground, should given priority positioning close Note that phase compensation with capacitors alone, with series resistors order inserted also possible. While this increase phase compensation effect, since increases parts count, recommend using capacitors only. However, recommend phase compensation with resistors inserted details layout, power amplifier subject oscillation. Also note that ceramic capacitor between pins only minimal phase compensation effect normal power amplifiers, required. However, there cases where does have large effect pattern layout, recommend creating dummy pattern this capacitor handling reserve component.

LA8519M Power amplifier VREF (pin line reference voltage power amplifier, connected (the input) internal bias resistor. This means that part power amplifier plus input line system. this line affected power amplifier output line, resultant positive feedback cause oscillation. Therefore, possible, line should routed around other lines. must routed around other lines, rout adjacent output lines, rout adjacent ground lines prevent interference. LA8519M ground line rerouting (See figure next page.) LA8519M circuit blocks classified into three systems: power amplifier, speech network system, crosspoint switch other small-signal processing systems. Since itself, naturally, three-block structure, each block independent ground pins. best possible ground system design, external components that connected ground connected ground block which they belong, pattern formed that these three lines independent connect ground power supply (regulator) that reference. However, since there limitations area available printed circuit board, there cases where single line connected reference ground. this case, ground lines must routed that ground lines that carry larger currents (power amplifier line connection blocks) closer power supply ground (and thus have lower impedance)than ground lines circuits with lower current drain. large currents used power amplifier other high-current system flow ground lines that handle smaller currents from small-signal system other low-current system, loop formed band oscillation occur. Therefore recommend that ground lines designed, described above, that lines which large currents flow routed closest power supply ground. Usage Notes LA8519M used vicinity maximum ratings, even slight variations operating conditions result maximum ratings being exceeded. Since this lead damage destruction device, provide adequate margin fluctuations supply voltage other parameters, allow maximum ratings exceeded. shorting LA8519M left with output loads shorted extended periods, damaged destroyed. Always this device manner such that output loads never shorted.
