3. Functional Descriptions
3.1 USB 2.0 Controller
The USB specifications revision 2.0 with the operational rate up to 480 Mbit/s. ALi’s
compliance-proven USB 2.0 controller design also provides the standard Isochronous-In USB
video class feature for the optimized system compatibility. The peripheral controller supports
USB suspend and resume operations to further reduce the actual operating and
suspend-mode power consumption for the USB-based system.
3.2 USB 2.0 Transceriver
M5603D built-in USB transceiver, Serial Interface Engine (SIE) and command decoder (UBL)
to be fully compliant with high/full-speed USB specifications revision 2.0/1.1 at operation rate
up to 480/12 Mbits/sec. The compliance-proven transceiver design provides two standard
differential single-ended connections for data transmission and reception. With existed
functional support to USB suspend and resume operation, M5603D utilizes ALi proven
low-power CMOS technology to provide cost-effective integration for the USB-based
peripheral system.
3.3 Embedded Micro-Controller Unit
The M5603D embeds a high-performance MCU to serve the USB engine to enable an
exceptional data transfer performance through the USB bus. The embedded MCU unit also
provides a very flexible programmability to ease the operations for image and audio access.

3.4 Image Sensor Interface
ALi M5603D provides programmable 8-bit video data bus with general serial control interface
for video transfer/control with target CMOS image sensor. With design integration and
programmability flexibility in mind, M5603D could be easily programmed to connect with
varieties of CMOS image sensors.
3.5 Audio Interface
With build-in ADC interface module, M5603D is capable of connecting to MIC circuit for
voice-capture and packaged through USB interface to constitute real-time audio/video based
applications.
3.6 Built-in On-Chip Clock Synthesizer
With on-chip clock synthesizer, M5603D is allowed to use nominal low-cost 12 MHz crystal (or
oscillator) by connecting to XTALI and XTALO, and generates standard internal 480 MHz
clock for USB interface. If the external 12 MHz clock source is available, the XTALI input pin
can be used as the clock input to provide more cost saving in the clock circuitry. Additional
clock output with two times of video pixel rate is provided for video capture module.
