BA6566F集成电路（IC）的电信规格书PDF中文资料

BA6566F属于集成电路（IC）的电信。由罗姆半导体集团制造生产的BA6566F电信电信接口集成电路 (IC) 为通信网络接口提供特定功能和控制，例如以太网切换、线路驱动器、ISDN、放大器、通道扩展器、数字锁相环、DTMF、音频发生器和解码器、回声消除、检测器和发生器、DDA、电话线路监控器和主叫号码标识。

The BA6566, BA6566F, and BA6566FP are speech network ICs which possess the basic functions required for handset communications. In addition to amplifying signals from a transmitter and sending them to a telephone line, they amplify only reception signals from a telephone line and drive the receiver. They also compensate for fluctuation in the volume at which signals are transmitted and received, caused by the length of the telephone line (AGC).

特性 Features

1) Can accommodate both dynamic and piezoelectric

receivers, simply by changing the circuit constant for

a wide dynamic reception range.

2) Automatic gain control (AGC) is used, based on the

transmission and reception telephone line current,

for easier compliance with communications standards.

3) Erroneous operation caused by high-frequency electrical

wave interference is minimized.

4) An HSOP package is used, eliminating the need for

an attached transistor to dissipate heat. This means

that a common circuit can be shared when a DIP

package is used (BA6566FP).

Applications

Telephones and telephone equipment
