CS5530A

Table 6-2 lists absolute maximum ratings for the CS5530A.Stresses beyond the listed ratings may cause permanent damage to the device. Exposure to conditions beyond these limits may (1) reduce device reliability and (2) result in premature failure even when there is no immediately apparent sign of failure. Prolonged exposure to conditions at or near the absolute maximum ratings may also result in reduced useful life and reliability These are stress ratings only and do not imply that operation under any conditions other than those listed under Table 6-3 is possible.

The AMD Geode™ CS5530A companion device is designed to work in conjunction with an AMD Geode™ GX1 processor. Together, the Geode GX1 processor and CS5530A companion device provide a system-level solu-tion well suited for the high performance needs of a host of devices which include digital set-top boxes and thin client devices. Due to the low power consumption of the GX1 processor, this solution satisfies the needs of battery pow-ered devices such as AMD's WebPAD system, and thermal design is eased allowing for fanless system design.

The CS5530A is a PCI-to-ISA bridge (South Bridge), ACPI-compliant chipset that provides AT/ISA style functionality.The device contains state-of-the-art power management that enables systems, especially battery powered systems,to significantly reduce power consumption.

Audio is supported through PCI bus master engines that connect to an AC97 compatible codec. If industry standard audio CS5531 is required, a combination of hardware and software called Virtual System Architecture™ (VSA) technology is provided.

The Geode GX1 processor's graphics/video output is con- nected to the CS5530A. The CS5530A graphics/video sup-port includes a PLL that generates the DOT clock for the GX1 processor (where the graphics controller is located),video acceleration hardware, gamma RAM plus three DACs for RGB output to CRT, and digital RGB that can be directly connected to TFT panels or NTSC/PAL encoders.
