ABSTRACT
This user's guide describes the evaluation module (EVM) for a RS232 transceiver TRS3232 with the RGT
package. This EVM helps designers evaluate the device performance for fast development and analysis of data
transmission.
1 Introduction
The TRS3232RGTEVM is an evaluation module for the TRS3232 and TRSF3232 devices, normal and high-
speed RS-232 transceivers.
1.1 Features
• Interface with MCUs or processor from 3 V up to 5.5 V
• High-speed RS-232 communication, up to 1 Mbps
• Robust IEC 61000-4-2 qualification provides robust protection from electrostatic discharge events
• DB9 female connector for direct connection with a computer's RS-232 port
• Headers for easy connection to all power and logic signals
1.2 Applications
Any application that needs short range point-to-point full duplex data communications with hardware flow control.
• Remote Radio Unit (RRU)
• Base Band Unit (BBU)
• Electronic Point of Sale (EPOS)
• Diagnostics & Data Transmission Battery-Powered Equipment
1.3 Description
The TRS3232RGTEVM is an evaluation module for the TRS3232 and TRSF3232 devices, normal and high-
speed RS-232 transceiver. The module enables device evaluation using the installed DB9 connector and
headers. The board interfaces data and controls CMOS logic levels on the headers to RS-232 levels supporting
data [RX, TX] channels and flow control [RTS, CTS] channels on the DB9 connector.
