Overview
The SN65LVCP114ZJA, produced by Texas Instruments, is an advanced asynchronous, protocol-agnostic, low-latency quad multiplexer (MUX) and demultiplexer (DEMUX) with linear redriver capabilities. This device is optimized for high-speed data transmission systems, supporting rates up to 14.2 Gbps. It is designed to compensate for channel loss in backplane and active-cable applications, ensuring optimal signal integrity and system performance.
The SN65LVCP114ZJA features a compact 12-mm × 12-mm × 1-mm PBGA package with a 0.8-mm terminal pitch, making it ideal for applications where board real estate is limited. The device operates on a single 2.5-V or 3.3-V power supply and includes features such as loopback mode, I2C control, and adjustable output swing for flexible EMI and crosstalk control.
