Introduction

SN65C3238DWE4 is an interface-Drivers, Receivers, Transceivers IC (Integrated Circuit) from Texas Instruments. It is a high performance octal line-driver/line-receiver that provides high-current drive capability for balanced transmission lines with line lengths up to 1000m. This IC can be used in a wide range of applications, from Ethernet and fibre channel networks to FPD-link and consumer audio products.

Features

The SN65C3238DWE4 IC has the following features:

• Ethernet compliant
• Max line length of 1000m
• High-Current driving capability
• 8-bit bus interface
• 3.3V single supply operation
• Wide Operating Temperature range(-40°C to +85°C)

Application Field

The SN65C3238DWE4 is suitable for use in user networks such as:

• Ethernet, Fast Ethernet, and Gigabit Ethernet applications
• Fiber Channel links
• FPD (Flat Panel Display) links
• Ethernet Power Over Ethernet applications
• Industrial and consumer audio products

Working Principle

The SN65C3238DWE4 is a high performance octal line-driver/ line-receiver which is designed to work in both Line-receive and Line-drive modes. The Line-receive mode only has two pins, namely Coding Index and Line Output, which are used to receive incoming signal and generate outgoing signal respectively. The Line-drive mode operates with two signal pairs, Coding Gate and Line Input, which are used to receive incoming signal and generate outgoing signal respectively.The SN65C3238DWE4 provides a 3.3V single-supply operation and can supply up to 8mA current with a maximum power dissipation of 1.1W. The SN65C3238DWE4 has a maximum line length of 1000m which is suitable for applications where higher line length transmission is required.The SN65C3238DWE4 is configured with an 8-bit bus interface which is used to control the Line-driver/Line-receiver modes. The 8-bit bus consists of input enable, enable/disable, and coding gate signals.In order to properly configure the SN65C3238DWE4, logic must be applied to the enable/disable signals to select the operating mode. The coding gate signals determine the operation mode by providing a logic “1” for Line-receive mode and a logic “0” for Line-drive mode.

Conclusion

In conclusion, the SN65C3238DWE4 is a high performance octal line-driver/line-receiver. It is designed to work in both Line-receive and Line-drive modes and is suitable for a wide range of applications such as Ethernet, FPD-link and consumer audio products. The SN65C3238DWE4 operates on a single 3.3V supply with a maximum line length of 1000m and offers a maximum power dissipation of 1.1W. The 8-bit bus interface enables the configuration of the Line-driver/Line-receiver modes.
