THine: 4Gbps, low voltage differential transceiver IC

THine announced the high-volume availability of their new GPIO / LVCMOS transceiver IC, THCS251. This new IC allows engineers to aggregate up to 37 lines of different data rates into just 4 lines that can be received and transmitted in the same IC! With the THCS251, manufacturers can lower cost, reduce size, and improve reliability by utilizing simplified and smaller hinges/slip rings in their product implementations.

The new THCS251 IC can be used in a wide variety of applications such as laptop computers, surveillance cameras, robotics, printing machines, medical equipment, gaming, XR devices, etc.

Many electrical devices, such as laptops, use hinges between their display and keyboard. Other devices, such as surveillance cameras, use slip rings to enable 360-degree rotation. These hinges and slip rings limit the number of wires that carry signals through them due to their physical space and/or cost.

In the past, SerDes technologies such as THine’s V-by-One HS, have solved many of these challenges. However, demand for more I/O is increasing as devices have more sensors to provide more accurate information for better user experiences. Thus, aggregation in addition to SerDes is needed to reduce the cable number of multiple different signal paths, thereby allowing more flexible implementations that can reduce product size and cost.

Using THine’s market proven mixed signal technologies, THCS251 serializes and aggregates up to 37 lines into a pair of 4Gbps high speed differential signals. THCS251 also deserializes and deaggregates the differential signals back to the original 37 lines allowing implementations of both the receiver and transmit directions with only 4 lines. Thus, using THCS251 on each side of the hinge or slip ring connector can enable new applications that require higher I/O counts.

Also, the solutions using the THCS251 offer more choices for physical harnesses than hinges or slip rings. For example, it can be used with a contactless connector from Keyssa Inc. that can offer a ruggedized, low latency, detachable HD camera solution. The high-speed differential signal path of the THCS251 is supported by 8B10B encoding and built-in adaptive equalization, allowing a distance of greater than 15 meters with standard cables.
