Here’s a detai LED explanation of the pin functions, circuit principle, packaging, and pinout. Additionally, I will also address 20 frequently asked questions (FAQs) regarding the HFBR-1521Z module.
1. Package and Pinout Overview
Brand: Broadcom (Avago Technologies) Package Type: Plastic Dual In-line Package (PDIP) or Surface Mount Package (SMD), which typically contains 6 pins for the standard module configuration.2. Detailed Pin Function Description
The HFBR-1521Z module typically comes in a 6-pin configuration. Below is the detailed description of each pin in this module.
Pin Number Pin Name Pin Function Description 1 Vcc ( Power Supply) Power supply input pin. It is used to connect to the positive supply voltage (typically +5V). Necessary for powering the internal circuitry of the module. 2 Ground (GND) Ground reference pin. Connects to the system's ground to complete the electrical circuit. It is used for the negative side of the power supply. 3 LED Anode (Anode) Anode pin of the internal LED. The LED is used for transmitting optical signals. This pin is connected to the LED's positive terminal. 4 LED Cathode (Cathode) Cathode pin of the LED. This is the negative side of the LED, used to complete the LED's current path. 5 Data Input (DIN) Input data pin. It is used for receiving serial data signals that are transmitted via the optical interface . The input voltage level is modulated to drive the LED. 6 Data Output (DOUT) Output pin for receiving the modulated optical signal. This signal is sent from the LED and will be decoded in the receiver section of the optical fiber system.3. Circuit Principle
The HFBR-1521Z module works by converting electrical signals into optical signals. The Data Input (DIN) pin receives serial data, which is then converted into an optical signal by the internal LED. The LED emits light based on the incoming data signal and is transmitted over a fiber optic cable. The Vcc pin provides the necessary power for the LED and internal circuitry, while the GND pin provides a return path to complete the circuit. The LED Anode and LED Cathode are the electrical connections for the LED, determining its polarity and allowing current to flow for operation. The optical signal is then received via the Data Output (DOUT) pin, where it can be decoded and processed by the receiving unit.4. 20 FAQ about the HFBR-1521Z
