1.6.3 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.
