DVD Processor for Low Cost DVD Players

Cirrus Logic 

CS98100

long data formats on DMA.

• Supports block transfers for graphics bit blits.

MPEG VIDEO DECODER

• Supports VCD1.0, 1.1, 2.0 and 3.0, SVCD, and

DVD video standards.

• Supports trick features, including smooth 2x

forward play.

• Special anti-tearing logic controls picture de-

code and presentation.

• Advanced error concealment hardware.

SYSTEM SYNCHRONIZATION

• System time clock (STC) for audio/video syn-

chronization

• Flexible interrupt structure for controlling de-

code and presentation times

• Hardware scheduling of sub-picture and high-

light events

AUDIO INTERFACE

• Supports 8 channels PCM, I2S at up to 24 bits

and 96 kHz output rate.

• Simultaneous IEC-958 output with program-

mable channel status and user data

• Also supports S/PDIF receiver for high perfor-

mance applications

EXTERNAL INTERFACE

• 2-wire serial master and slave port, second 2-

wire master port for controlling DVD device.

• 3- or 4-wire serial master/slave port.

• Large number of programmable bi-directional

I/O pins.

• All pins not used for other function can be reas-

signed as general purpose I/O pins

• 8 pins can be used as edge or level detection in-

terrupt pins.

• Hardware-assisted support for infrared remote

devices, such as remote control, infrared key-

board, mouse, printer, and more.

• Programmable parallel host master interface

supports formats including ATAPI, ISA, and

more.

• IO channel interface supports standard DVD

loader protocols

• Separate serial DVD interface to support low-

cost (track buffer-less) loaders

VIDEO PROCESSOR

• On screen display module supports 2-bit or 4-

bit, pixel modes. It supports 3 separate regions

and 16 transparency overlay levels

• High quality scaling using 16 tap polyphase

programmable vertical and horizontal filters, to

support any size image up to 768x576.

• Multiple video plain overlays (main video /

subpicture / picture-in-picture / on-screen dis-

play).

• Gamma Correction.

• Progressive scan video output

VIDEO ENCODER

• Three 10-bit video DACs, drive 37.5Ω load di-

rectly without external buffering

• Supports PAL (B,D,G,H,I,N) and NTSC

• Component (RBG or YUV) or composite + S-

Video output

• Progressive or interlaced mode output

• Macrovision 7.1 support (interlaced) and Mac-

rovision 1.03 support (progressive)

• Wide-screen signaling support (interlaced and

progressive) and CGMS support

• Closed captioning support

SUB-PICTURE PROCESSOR

• Run-length decode DVD sub-pictures and

SVCD OGT formats

• Hardware vertical scaling supports NTSC-PAL

format conversion

• 16 level alpha blending

System Functions

• 208-pin MQFP package.

• All I/O pins are 3V with 5V tolerance.

• Advanced 0.18 micron CMOS technology.

• Chip runs at 90 MHz

• Supports Low power modes and clock shutoff.
