Logic - Signal Switches, Multiplexers, Decoders are all circuit switching devices that are used to route signals from one source to another. The PI3B16234AE is a high-performance, four channel, differential multiplexer that allows two channels of multiplexed data to be switched between four inputs. In this article, we will discuss the application field and working principle of PI3B16234AE.

The PI3B16234AE is designed for applications where high-speed and low-power multiplexing is required, such as in optical networking, automotive infotainment systems, and other demanding telecom and data communication systems. It features four differential inputs with low-voltage differential signaling (LVDS) supporting data rates up to 5 Gbps. The device also features a low operating power and small size, making it ideal for space-constrained designs.

The PI3B16234AE consists of a four-channel multiplexer and four pairs of differential output buffers. The multiplexer can be operated in a 4:1 scheme with four data inputs, each with its own pair of differential outputs. Alternatively, it can be employed in a 2:1 scheme with two inputs and two outputs. The multiplexer provides two output data streams that are routed from one of the four input channels.

The multiplexer is controlled by two select pins, SELA and SELB. These pins allow for the selection of one of four input channels. SELA and SELB are used for decoding the address and the selection of the desired data channels. When using the device in the 2:1 configuration, SELA is used to select the desired channel, while SELB is held at low or high logic levels as needed. In addition, the device features an enable pin, EN, which is used to control the output enable state.

The outputs of the PI3B16234AE are driven by four differential output buffers which provide the high-speed differential bidirectional LVDS signal transmission. The buffers have slew-rate control which allows the user to adjust the transition time and minimize the overshoot. Additionally, the output buffers offer a high output voltage level of up to 800mV and low propagation delay of under 10ns.

The PI3B16234AE is ideal for applications that require high-speed and low-power multiplexing. Its four differential inputs and two select lines allow for flexible use and the output buffers offer high-speed LVDS transmission with audio-grade line driver characteristics. In addition, the low power consumption and small size make the device an ideal solution for space-constrained applications.
