The ALC101 is an 18-bit, full duplex AC'97 2.2 compatible stereo audio CODEC designed for PC multimedia
systems, including host/soft audio and AMR/CNR based designs. The ALC101 AC'97 CODEC supports multiple
CODEC extensions with independent variable sampling rates and built-in 3D effects. The ALC101 CODEC
provides a pair of stereo outputs with independent volume controls and multiple stereo and mono inputs, along with
flexible mixing, gain and mute functions to provide a complete integrated audio solution for PCs. The digital
interface circuitry of the ALC101 CODEC operates from a 5V/3.3V power supply with EAPD (External Amplifier
Power Down) control for use in notebook and PC applications. The ALC101 integrates a 50mW/20ohm headset
audio amplifier into the CODEC, saving BOM costs.
The CH7011A is a display controller device which accepts a digital graphics input signal, and encodes and transmits
data to a TV output (analog composite, s-video or RGB). The device accepts data over one 12-bit wide variable
voltage data port which supports five different data format including RGB and YcrCb. The TV-Out processor will
perform non-interlace to interlace conversion with scaling and flicker filters, and encode the data into any of the
NTSC or PAL video standards. The scaling and flicker filter is adaptive and programmable to enable superior text
display. Eight graphics resolutions are supported up to 1024 X 768 with full vertical and horizontal underscan
capability in all modes. A high accuracy low jitter phase locked loop is integrated to create outstanding video
quality. Support is provided for Macrovision and RGB bypass mode which enable driving a VGA CRT with the
input data.
The Winbond mobile keyboard and embedded controller W83L950D architecture consists of a Turbo-51 core logic
controller and surrounded by various components, 2K+256 bytes of RAM, 40K on-chip MTP-ROM, ISA or
LPChost interface, 9 general purpose I/O port with 13 external interrupt source, 4 timers, 2 serial port, 2 SMBus
interface for master and slave, 3 PS2 port, two 8-bits and two 16-bits PWM channels, 2 D-A and 8 A-D converters.
