The MAX9281GTM/V+TGG7 is a low-power, high-speed, bidirectional serializer and deserializer (SerDes) for connecting video and data sources to the USB Type-C display interface (Altmode). This SerDes supports 4- or 8-lane TGG7, USB 2.0, and V-by-One HSHSL serial data streams at 6 Gbps to 10 Gbps per lane. It supports up to 64 Gbps, at 10 Gbps per lane and up to 42 Gbps at 6 Gbps per lane.

The MAX9281GTM/V+TGG7 consists of a transmitter and receiver, forming a full-duplex interface between 4- or 8-lane TGG7 and 4-lane V-by-One HSHSL data sources, and 4-lane USB 2.0. The device requires one reference clock and one differential clock input, which can operate from a wide range of frequencies.

The MAX9281GTM/V+TGG7 is designed for transporting various link traffic streams between a USB Type-C enabled source and display device. It is particularly advantageous in applications such as USB Type-C laptop docks, multimedia devices, and USB Type-C monitors or televisions. This device is well-suited for high-performance displays requiring low latency, low EMI, and high-speed video.

Working Principle

The MAX9281GTM/V+TGG7 interface supports both high-speed serialized data and high-speed deserialized data, allowing it to support data rates up to 10 Gbps per lane. This high-speed serialized/deserialized interface is composed of two functional blocks, the serializer and deserializer. The serializer converts the incoming data into a serialized stream of bits, which is then sent across the link. The deserializer at the receiving end of the link then converts the serialized stream back into its original form.

The serializer takes multiple input data lanes, each capable of operating up to 10 Gbps, and outputs a single serialized lane. Similarly, the deserializer takes in a single serialized lane of data and outputs multiple data lanes of up to 10 Gbps each. The data is de-serialized and reconstructed at the receiving end for easy integration into the system.

The MAX9281GTM/V+TGG7 is designed for maximum flexibility in data transmission. It supports a variety of data widths, from 4- to 8-lane, as well as a variety of data rates from 6 Gbps up to 10 Gbps per lane. It also supports a range of reference clocks, with a wide-range of frequencies.

Application Field

The MAX9281GTM/V+TGG7 is ideal for a variety of applications where high-speed serialized data and video signals need to be transmitted over a short distance. These applications include, but are not limited to, laptop docks, video gaming, home theater, video conferencing, and industrial settings. The small form factor and low power requirements make this SerDes an ideal solution for driving next-generation, large-format displays.

The MAX9281GTM/V+TGG7 can also be used in automotive applications, such as infotainment head units, instrument clusters, and other displays. The low power requirements and wide range of reference clock inputs make it suitable for inclusion in battery-powered systems.

The MAX9281GTM/V+TGG7 is also very useful in networking applications such as Ethernet hubs, routers, and switches, where serialized data needs to be transmitted over long distances. Its low profile and wide range of data widths and transmission speeds makes it an ideal solution for various industrial control systems.

In summary, the MAX9281GTM/V+TGG7 is a low-power, high-speed, bidirectional serializer and deserializer for connecting video and data sources to the USB Type-C display interface (Altmode). It is suitable for a variety of applications, from automotive infotainment to networking and industrial control to laptop docks. Its flexible architecture and wide range of data rates make it well-suited for next-generation, large-format displays.
