Transmit FIFO Buffer Component – Computer, Electronic and Optical Product Manufacturing

Component Specifications

Definition

A Transmit FIFO Buffer is a specialized memory component within a Media Access Control (MAC) controller that temporarily stores outgoing data packets in a sequential queue, ensuring orderly transmission over network interfaces by managing data flow between the processor and physical layer devices.

Working Principle

Operates on the First-In-First-Out principle where data packets enter at the write pointer and exit at the read pointer, maintaining transmission order while providing flow control and preventing data loss during high-speed communication.

Materials

Semiconductor silicon with CMOS technology, typically fabricated using 28nm-65nm process nodes with copper interconnects and low-k dielectric materials.

Technical Parameters

Data Width 32-128 bits
Buffer Depth 64-512 entries
Interface Type AMBA AXI/AHB or proprietary bus
Clock Frequency 100-500 MHz
Operating Voltage 1.0-1.8V
Power Consumption 10-50 mW

Standards

ISO/IEC 8802-3, IEEE 802.3, JESD22

Frequently Asked Questions

What is the primary function of a Transmit FIFO Buffer?

To temporarily store outgoing data packets in sequential order, ensuring smooth transmission flow between the processor and network interface while preventing data collisions and loss.

How does buffer depth affect transmission performance?

Deeper buffers allow more data packets to be queued, reducing transmission latency and improving throughput during burst traffic, but increase silicon area and power consumption.
