Realtek manufactures and sells a wide variety of products throughout the world, and its product lines can be broadly categorized into two subdivisions: Communications Network ICs, and Computer Peripheral and Multimedia ICs. Included among the communications network IC products manufactured and provided by Realtek are: network interface controllers, (both the traditional 10/100M Ethernet controllers and the more advanced Gigabit Ethernet controllers), physical layer controllers (PHYceivers), network switch controllers, gateway controllers, wireless LAN ICs, as well as ADSL router controllers. In particular, the RTL8139 series 10/100M Fast Ethernet controllers met their height during the late 90’s, and continued to take up a significant, and eventually predominant share in the worldwide market in the following years. Those devices categorized as Realtek’s computer peripheral and multimedia IC products, are comprised of the traditional AC97 audio codecs, the High Definition audio codecs, card reader controllers, clock generators, IEEE 1394 ICs, and LCD controllers.

The most notable Realtek products are 10/100M Ethernet controllers, with a global market share of 70% as of 2003, and AC97 audio codecs, where Realtek's market share is 50%, primarily concentrated in the integrated OEM on-board audio market segment. Presently the ALC850 and RTL8139 are particular OEM favorites, offering low prices, and basic feature sets. RTL8139-based NICs are dubbed "crab cards" in Taiwan, alluding to the crab-like appearance of the Realtek logo. 2003 (MMIII) was a common year starting on Wednesday of the Gregorian calendar. ...

It has been announced or projected, on several different occasions, that Realtek will, in the future, focus its R&D resources in the field of digital television technologies, as well as more advanced wireless communications technologies such as ultra-wide band (UWB) communications and the yet-to-be-realized 802.11n standard. It seems clear that Realtek has been setting its eye on pursuing the Holy Grail of the anticipated new applications and needs derived from the concept of Digital Home proposed by Intel. Digital television (DTV) is a telecommunication system for broadcasting and receiving moving pictures and sound by means of digital signals, in contrast to analogue signals in analogue (traditional) T.V.

Awards

Realtek's single-chip fast ethernet controller, the RTL8139, receives "Best Component" and "Best of Show" awards at Computex-Taipei '97. Seven years later, its dual-band triple-mode WLAN solutions, which includes a baseband processor/media access controller RTL8185L and an RF chip RTL8255, again receive “Best Choice of Computex” award at Computex-Taipei 2004. Computex Taipei (formal name: Taipei International Information Technology Show) is a computer expo held annually at the Taipei World Trade Center in Taipei, Taiwan. ...


Criticism

Realtek's products have sometimes met with criticism. From the kernel sources for the FreeBSD operating system, the comment has been made that, "the RealTek 8139 PCI NIC redefines the meaning of 'low end.' The 8139 supports bus-master DMA, but it has a terrible interface that nullifies any performance gains that bus-master DMA usually offers."[1] However, OpenBSD developer Theo de Raadt once praised Realtek - "the (newish) Realtek Gigabit Ethernet chips are not too bad at all, and there's lots of documentation. So maybe the Taiwanese products are a little bit later to the market, but they are simpler and robust once they do make it to the market."
