CS5530 Datasheet | National Semiconductor

Description The CS5530 I/O panion is designed to work in conjunction with the GXLV and GXm series processors; all members of the National Semiconductor® Geode™ family of products. Together the Geode processor and CS5530 provide a system-level solution well suited for the high performance needs of a host of devices such as digital set-top boxes and thin client devices. Due to the low power consumption of a GXLV processor, this solution satisfies the needs of battery powered devices such as National’s Web PAD™ system, a Geode GXLV processor/CS5530 based design. Also, thermal design is eased allowing for fanless system design. The CS5530 I/O panion is a PCI-to-ISA bridge (South Bridge), ACPI-pliant chipset that provides AT/ISA style functionality. To those familiar with PC architecture this enables a quicker understanding of the CS5530’s architecture. 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 which connect to an AC97 patible codec such as the National Semiconductor LM4548. If industry standard audio is required, a bination of hardware and software called Virtual System Architecture® (VSA™) technology is provided. The GXLV processor’s graphics/video output is connected to the CS5530. The CS5530 graphics/video support includes a PLL that generates the DOT clock for the GXLV 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. The digital RGB output can also be connected to the National Semiconductor CS9210 Graphics panion (a DSTN Controller) for DSTN panel support. The CS9210 is also a member of the Geode product family.
