The PI2PCIE412-CZHEX, designed by Pericom, is a part of the Interface - Analog Switches - Special Purpose category. As part of this specific grouping, the PI2PCIE412-CZHEX is built in order to provide a wide range of functionalities, from driving automotive infotainment and entertainment systems, to controlling I/O-rich sets of equipment, such as network appliances, storage, and gateways.

In essence, the PI2PCIE412-CZHEX provides a two-channel, parallel-input and serial-output bus interface. It is available in a small-edge footprint, making it suitable for use with system designs and architectures with limited space or physical envelope constraints. The PI2PCIE412-CZHEX was designed to scale with industrial requirements, since the board supports operation from 1.2V to 3.3V, with a maximum power dissipation of 14.5mW per channel.

The application field of the part covers a wide range of usage scenarios, including industrial, automotive, and telecoms. It is also suitable for use in computer and communications applications, where high-speed, low latency connections are a requirement; it is suitable for PCI Express, SAS, SATA, and Ethernet connections. The part\'s serial interface allows for low-power, low-latency communication between two points independent of data width, enabling the use of a common cable and connector across multiple applications. Finally, the part has data performance of up to 8.6Gbps while maintaining a deterministic latency of 2.5nS.

The part supports both symmetric and non-symmetric data, as well as half-duplex and full-duplex operations. It also has excellent switching characteristics, allowing for high-speed multiplexing, crosspoint selection, and synchronous data transfer between the two points. The PI2PCIE412-CZHEX also provides excellent power savings when compared to traditional multi-channel systems, due to the low-power dissipation.

The working principle of the part involves two channels that can be used either in parallel-inputs/serial-outputs mode or in serial-inputs/serial-outputs mode. When used in the former mode, the output is fed through the two input channels in order to generate the serial output. In the latter mode, the data is transferred in a half-duplex or full-duplex mode, depending on the user\'s needs. The part also supports handshaking protocols, such as the ACK/NAK interface, to facilitate two-way communication.

In conclusion, the PI2PCIE412-CZHEX is an excellent choice for I/O-rich sets of equipment, such as network appliances, storage, and gateways, as well as for automotive and industrial applications. It offers high-speed, low-latency communications, with excellent power savings and fast switching characteristics. It is suitable for use in PCI Express, SAS, SATA, and Ethernet connections, and provides excellent data performance, with a maximum of 8.6Gbps and a deterministic latency of 2.5nS.
