ST7538集成电路（IC）的驱动器接收器收发器规格书PDF中文资料

ST7538属于集成电路（IC）的驱动器接收器收发器。由意法半导体集团制造生产的ST7538驱动器，接收器，收发器该系列产品的主要功能是提供必需的硬件资源，以通过延长电缆或印制线进行通信。确切的功能会因所采用的通信协议而异，可能包括诸如瞬态抑制之类的功能，这些功能对于通信用途可能并非绝对必要，但对于可能的使用环境却是明智之选。

DESCRIPTION

The ST7538 is a Half Duplex synchronous/asynchronous FSK Modem designed for power line communication network applications. It operates from a single supply voltage and integrates a line driver and a 5V linear regulator. The device operation is controlled by means of an internal register, programmable through the synchronous serial in terface. Additional functions as watchdog, clock output, output voltage and current control, preamble detection, time-out, band in use are included. Realized in Multipower BCD5 technology that allows to integrate DMOS, Bipolar and CMOS structures in the same chip.
