V-by-One® HS Comparing with FPD Link III and GMSL

Introduction

Sometimes we are asked by customers “Is V-by-One® HS same as FPD Link III or GMSL?” This page is to explain what makes V-by-One® HS different from FPD Link III or GMSL.

Texas Instruments’ FPD Link III and Maxim (an Analog Devices) GMSL are known as high-speed video SerDes supporting many features like:

  • Up to ~4Gbps per lane

  • Coaxial Cabling Support

  • Up to 15-meter Transmission

  • Bi-directional Communication

  • No Latency

An Application Example for THine’s V-by-One® HS IC Products | See “Ser” (Serializer) and “Des” (Deserializer), for which TI and Maxim have similar IC products.

These features apply to V-by-One® HS as well. However, as each technology has been developed and introduced to market differently, V-by-One® HS has following unique points from technology and business aspects.

Technology Uniqueness

  • Robustness against video frequency changes

  • Independent low-speed data link (Sub-Link)

    • Ideal for debugging

    • Open doors for contactless transmission

  • Video Replication Mode

Business (Design and Production) Uniqueness

  • Intense Support along with Tools

  • Supply Allocation Program

  • Japan Quality

Note: Each technology is a different protocol. Thus, unless the chipset is designed to replace one of others, starting to use one instead of another that you have used will require a new design.

V-by-One® HS Technological Uniqueness

Robustness against Video Frequency Changes

V-by-One® HS’ first major application was TV, where there were multiple video input sources, analog video, VCR, STB, DVD player, etc. The frequency of each video source can be anything while everything needs to be displayed in the same screen. THine’s V-by-One® HS IC products were all designed to accept any of them, supporting from 600 Mbps to over 3 Gbps.

Independent Low-Speed Data Link (Sub-Link)

Camera applications typically need low-speed bidirectional communication channel to control camera settings from Application Processor. It is one solution to consolidate the video line and the control line (and sometimes power as well), so that the line count between camera and application processor is significantly reduced. However, what we have learned from designing customers was that in designing phase which includes debugging work it is critical to be able to identify the root cause for each error and if the video line and control line is always embedded, it makes the debugging process significantly hard. This is the reason V-by-One® HS products input/output the video line and control line separately. If you need to use a coaxial cable, it is still doable right after the transmitter and before the receiver.

This link separation invites another design possibility. A technology called Contactless Connection enables high-speed electrical data transmission to go over short distance of air, allowing the connection completely sealed with a plastic case. Ideal method for water/oilproof applications. This technology however requires no-embed high-speed transmission. Among V-by-One® HS, FPD Link III, and GMSL, only V-by-One® HS is compatible with this unique technology. For proof of concept example, go to THine and Keyssa launch a Detachable HD Camera System Solution.

Video Replication Mode

Interface conversion is not the only function THine’s IC products provide. The Video Replication function is developed to support dual displays with one source. For example, large-sized digital signage display may equip a tiny display on the back side for maintenance purpose. (Without this tiny display, you would have no idea what it displays when you are managing at the other side of the ‘wall’!) This function is not limited to displays. Some applications need to log (store) video from its camera. With this function, you can feed a logger without affecting the main video path. In addition, by using the Contactless Connection described in previous section, you would be able to hide the data output point except for maintenance technicians who know where it is.

By using the Video Replication Mode at both Serializer and Deserializer, the camera images are provided to 4 different application processors or sinks.

V-by-One® HS Uniqueness for Design and Production Phases

Intense Support along with Tools

THine’s business started with listening to customers who were having a hard time establishing digital video architecture. In other words, we have not generated reference designs with BOM that nobody knows if all parts are available when a customer goes production. We are committed to understand each customer’s application and generate the best and viable solution with the customer, in which process we develop Tools, such as Vision System Starter Kit (VSSK).

Supply Allocation Program

When THine’s products started being used by major consumer OEMs, we worked so closely with world leading foundries and assembly sites that THine established a unique production management system to understand the production details as if the factories were dedicated to THine. With such partnership, we manage product supply with minimal delays.

Japan Quality

THine Electronics has served video interfacing applications in TV and related consumer market since 1992, establishing outstanding reputation for its reliable products and intense support. Partnering with global reputable foundries and assembly companies, THine manages the whole manufacturing process in Japan. Some of its products are more than 20 years old. THine has never ended life of any video interface product without providing succeeding product.
