Improved Signal Integrity: </strong>The I2C extender module enhances the rise time conversion on the I2C bus, ensuring the integrity of data transmission among multiple devices connected to the bus. This leads to more reliable and accurate communication.<br /> <strong>2. Wide Power Supply Voltage Range: </strong>With a voltage range of 1.6V to 5.5V, the active terminator provides flexibility and compatibility with various power supply systems. It can accommodate different voltage levels, making it suitable for a wide range of applications.<br /> <strong>3. High Frequency Operation: </strong>Capable of operating at frequencies up to 400kHz, the I2C active terminator allows for fast and efficient data transfer. This enables quick communication between devices, reducing latency and improving overall system performance.<br /> <strong>4. Low Power Consumption:</strong> The I2C extender features automatic detection of low-power standby mode, ensuring energy efficiency when not actively transmitting data. With a power current cutoff of less than 5μA, it minimizes power consumption and extends battery life in portable devices.<br /> <strong>5. ESD Protection:</strong> The signal amplifier is designed to withstand electrostatic discharge (ESD) with a ±8kV human body model ESD durability. This ensures reliable operation even in environments with potential ESD risks, providing added protection to the connected devices and the I2C bus. </p><br/><br/><span><strong>Specification:</strong></span><br /> <span>Origin: Mainland China</span><br /> Description<br /> I2C stands for Inter-Integrated Circuit Communication and is meant for short distance communication on a PCB or assembly. But hey, we're engineers and we like to push the limits of technology, right? So why not try to get I2C to run over a meter of cable or even longer? Well, if you try that, you'll quickly find that the length of the cable adds capacitance and resistance that slows down the open-drain pull-ups used in I2C, making it hard to use 100KHz+ clock speeds. You can try slowing down the I2C clock to 1 KHz... or you can use an active terminator like this LTC4311!<br /> Using this board is simple: connect it to the I2C bus at the beginning of the chain (you can also try it at the end of the chain if you don't have really long cables). When the chip is powered up and enabled, it will monitor the SCL and SDA lines. When it sees them pulled up via the I2C resistors, it will activate and dump some current to boost them via the top power rail.<br /> You can now achieve faster data rates without the use of resistors and long cables. We easily ran a 400 KHz OLED over 3 meters of phone line. For 100KHz signals, we even ran a BME680 over 100 feet of Ethernet (about 3000pF round trip!) and used the OLED to display sensor details.<br /> Operates on any bus voltage from 1.6V to 5.5V, SCL speeds up to 400 KHz, and cables up to 4000pF. No special firmware, software, or configuration required. Simply plug the power, ground, SCL, and SDA connectors into the bus and watch the rise times magically turn sawtooth waves into square waves.<br /> Product Size: 25.00x18.00x5.00mm/0.98x0.71x0.2inch<br /> Product Material: Mixed Material<br /> <br /> <p> <strong>Note:</strong><br /> Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
