4.10.2 Video Clock
SIS 650 North Bridge provides input to generate VGA internal slate machine, MCLK, and
DCLK. Also provides 32.768 KHz O/P for video RAM refresh.
4.11 PCMCIA Controller
The PCMCIA controller of the notebook is implemented on the motherboard using the ENE
CB1410 CardBus Controller. The M785 notebook only supports single PCMCIA slot for PCI-
Cardbus Bridge.
CARDBUS CONTROLLERS
The CB1410 is an ACPI and PC98/99 logo certified high performance, single slot PC Card
controller with a synchronous 32-bit bus master/target PCI interface. This PC Card to PCI
bridge host controller is compliant with the 2000 PC Card Standard. This standard
incorporates the new 32-bit CardBus while retaining the 16-bit PC Card specification as
defined by PCMCIA release 2.1. CardBus is intended to support "temporal" add-in functions
on PC Cards, such as Memory cards, Network interfaces, FAX/Modems and other wireless
communication cards, etc. The high performance and capability of the CardBus interface will
enable the new development of many new functions and applications.
The CB1410 CardBus controller is compliant with the latest ACPI-PCI Bus Power
Management interface Specification. It supports all four power states and the PME# function
for maximum power savings and ACPI compliance. Additional compliance to On Now Power
Management includes D3 cold state support, paving the way for low sleep state power
consumption and minimized resume times. To allow host software to reduce power
consumption further, the CB1410 provides a power-down mode in which internal clock
distribution and the PC Card socket clocks are stopped. An advanced CMOS process is also
used to minimize system power consumption.
The CB1410 single PCMCIA socket supports the 3.3V/5V 8/16-bit PC Card R2 cards or 32-
bit CardBus R3 cards. The R2 card support is compatible with the Intel 82365SL PCIC
controller, and the R3 card support is fully compliant with the 2000 PC Card Standard
CardBus specification. The CB1410 is an additional buffer chip for the PC Card socket
interface. In addition, the CB1410 supports dynamic PC Card hot insertion and removal, with
auto configuration capabilities.
