7.4. Sound
The codec LM4548 provides the SC1200 audio system with a high quality audio path and all analog functio-
nality. It features full-duplex stereo ADC's and DAC's and an analog mixer with four stereo and three mono
inputs. Each input has separate gain, attenuation and mute control.
Features
-
Fully compliant AC97 analog I/O component
-
18bit stereo full-duplex codec
-
Programmable independent sample rates from 4kHz to 48kHz
National 3D sound stereo enhancement
-
-
True line level output with volume control in addition to standard line out
-
Stereo input for auxiliary audio
7.5. Compact Flash Socket (True IDE compatible)
A Compact Flash socket for commercial CF cards (Type
can serve as boot drive and is not hot-pluggable.
7.6. Ethernet 10BASE-T/100BASE-TX LAN
Overview
The DM9102A is a fully integrated and cost-effective single chip Fast Ethernet NIC controller. It is designed with
the low power and high performance process. It is a 3.3V device with 5V tolerance then it supports 3.3V and 5V
signaling.
The DM9102A provides direct interface to the PCI-Bus. It supports bus master capability and fully complies with
PCI 2.2. In media side, the DM9102A interfaces to the UTP3, 4, 5 in 10Base-T and UTP5 in 100Base-TX. It is
fully compliance with the IEEE 802.3u specification. Its auto-negotiation function will automatically configure the
DM9102A to take the maximum advantage of its abilities. The DM9102A is also support IEEE 802.3x full-duplex
flow control.
