Those devices categorized as Realtek's computer peripheral IC products consist of the traditional AC'97 audio codecs, the High Definition Audio codecs, card reader controllers, clock generators and IEEE 1394 ICs.

In particular, the RTL8139 series 10/100M Fast Ethernet controllers reached their height during the late 1990s, and continued to take up a significant, and eventually predominant share in the worldwide market in the following years. Products Ĭommunication network IC products manufactured and marketed by Realtek include: 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. Realtek's Audio Solutions are based on Avance Logic technology, which can also be recognized by the prefixes 'ALG' (Avance Logic Graphics) and 'ALS' (Avance Logic Sound). Avance Logic was acquired by Realtek as early as 1995 and was an independent subsidiary until the end of 2002, when the company was integrated into Realtek. A 3D accelerator was developed in the mid-1990s, but it was not widely used. Avance Logic focused particularly on the development of low-cost, highly integrated electronic components for OEM manufacturers and was active in the areas of 2D graphics and audio.

was a hardware manufacturer founded in 1991 in Fremont, California, and was most recently headquartered in San Jose, California.
