Interface - Drivers, Receivers, Transceivers

The WJLXT972MLC.A4-864101 is a low power, high performance interface solution from Lattice Semiconductor, specifically designed for embedded applications requiring low power and efficiency.

This device is a member of the LatticeXT family and is capable of supporting a maximum data rate of 2.5 Gbps. It features eight channels of serial input/output (TX/RX) with integrated polarisers, enabling it to support a wide range of protocols, including Serial ATA, Fibre Channel, SPDIF (I2S), PCI Express and many others.

The WJLXT972MLC.A4-864101 is ideal for use in both consumer and embedded applications, such as portable communication devices, automotive infotainment systems, industrial controllers, video cameras and image capture.

The main application field of the device is in digital video projection, where it is used for the transmission of high-resolution video at lower speeds. It is capable of transferring up to four pixels simultaneously, allowing for a smooth video picture at 1080p resolution.

The WJLXT972MLC.A4-864101 also enables the high-speed transfer of Gigabit Ethernet, USB, PCI Express and other complex data formats. It supports a wide range of protocol-specific functions, with built-in deserializers, error checking and correction, and other power-saving features.

Working Principle:

The WJLXT972MLC.A4-864101 is a serializer/deserializer and receiver system, consisting of four individual controllers that interface with the external system. The polarity is configured to support HDTV and other protocols. The WJLXT972MLC.A4-864101 consists of the transmitter, deserializer and receiver.

The transmitter is a high-speed LatticeSX FPGA device, which receives data from the system and transfers it onto the serial link. It also performs ‘byte stuffing’, which is a technique used to ensure that all data bits are evenly spread across the data link. The byte stuffing technique is also used to overcome the effect of the crosstalk by allowing the data rate to be increased.

The deserializer is a digital logic device, which decodes the transmitted serial data so that digital logic signals can be generated from the data. It consists of a finite state machine and some additional logic, which has the ability to detect and identify the start of frames and reset the system. The deserializer also reconstructs the commands and data that it receives from the transmitter, to facilitate the transfer of data between the entities.

The receiver is the final device in the chain, and it is responsible for reconstructing the data received from the deserializer. The receiver also compares each received word with the transmitted word to check for errors, and it is also capable of detecting and correcting single-bit errors in the data. The receiver is powered by a specialisLattice communication interface, which enables it to detect any data rate.

The WJLXT972MLC.A4-864101 is also capable of providing a flexible, power-saving solution, thanks to its low power consumption. It is one of the most efficient devices currently available for digital video projection.
