VIA VT1612A Audio Codec 
VIA Technologies’ VT1612ATM 18-bit audio codec conforms to the AC’97 2.2. The 
VT1612A integrates Sample Rate Converters and can be adjusted in 1Hz increments. The 
analog mixer circuitry integrates a stereo enhancement to provide a pleasing 3D surround 
sound effect for stereo media. 
Furthermore, an integrated headphone amplifier with thermal shutdown adds signal value 
by reducing the BOM. This codec is designed with aggressive power management to 
achieve low power consumption. When used with 3.3V analog supply, power consumption 
is further reduced. The primary applications for this part are desktop and portable personal 
computers multimedia subsystems. 
1.6.4 Ethernet 
1.6.4.1 Realtek 
RTL8100C Ethernet Controller 
The Realtek RTL8100C(L) is enhanced with an ACPI (Advanced Configuration Power 
Interface) management function for PCI in order to provide efficient power management for 
advanced operating systems with OSPM (Operating System Directed Power Management). 
It also supports remote wake-up (including AMD Magic Packet™ and Microsoft® Wake-up 
frame) to increase cost-efficiency in network maintenance and management.
