1.1.2.5 CH7011A <strong>8080</strong> N/B Maintenance The CH7011 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 formats 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 by 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 enables driving a VGA CRT with the input data. Features : TV output supporting up to 1024x768 graphics resolutions Macrovision 7.X copy protection support Programmable digital interface supports RGB and YCrCb True scale rendering engine supports underscan in all TV output resolutions Enhanced text sharpness and adaptive flicker removal with up to 7 lines of filtering Support for all NTSC and PAL formats Provides CVBS, S-Video and SCART (RGB) outputs TV connection detect Programmable power management 10-bit video DAC outputs 21
Fully programmable through serial port Complete Windows and DOS driver support Low voltage interface support to graphics device 1.1.2.6 Super I/O_NS PC87393 <strong>8080</strong> N/B Maintenance National Semiconductor’s PC8739x family of LPC Super I/O devices is targeted for a wide range of portable applications. PC99 and ACPI compliant, the PC8739x family features an X-Bus Extension for read and write operations over the X-Bus, a full IEEE 1284 Parallel Port with a Parallel Port Multiplexer (PPM) for external Floppy Disk Drive (FDD) support, a Musical Instrument Digital Interface (MIDI) port, and a Game port. Like all National LPC Super I/O devices, the PC8739x offers a single-chip solution to the most commonly used PC I/O peripherals. The PC8739x family also incorporates: a Floppy Disk Controller (FDC), two enhanced Serial Ports (UARTs), one with Fast Infrared (FIR, IrDA 1.1 compliant), General-Purpose Input/Output (GPIO) support for a total of 32 ports, Interrupt Serializer for Parallel IRQs and an enhanced WATCH DOG timer. 22
