W9971CF
GENERAL DESCRIPTION
Winbond s W9971CF is a highly-integrated VLSI providing high performance graphics acceleration
and TV-quality full screen motion video acceleration for IBM PCs or compatibles. The W9971CF
integrates an NTSC/PAL TV encoder with S-Video or composite video for flicker-free and glueless
TV output. An on-chip RAMDAC and a dual programmable clock synthesizer with a 170 MHz pixel
data rate are also integrated into the chip to simplify system design and reduce cost.
The W9971CF is a high-performance graphics accelerator specially designed for Microsoft
Windows, Mac OS, IBM OS/2, and DOS-based applications. In addition to 100% IBM VGA register-
level compatibility, the W9971CF incorporates a 64-bit graphics engine (GE) to accelerate drawing
functions such as bit block transfer (BitBLT), line drawing, clipping, and hardware cursor
manipulation.
The W9971CF s integrated video accelerator (VA) features high-quality video filtering, bilinear
interpolating scaling along both the X and Y axes, color space conversion and overlay keying. In
addition to accelerating software video playback, the W9971CF also provides an advanced
multimedia video interface for glueless interfacing to major TV decoders such as the Philips
SAA711X and the Brooktree Bt815A/7A/9A. The 16-bit baseline VESA Advanced Feature
Connector (VAFC) and the 8-bit bidirectional IBM Feature Connector are also supported for legacy
video applications. By performing scaling and color space conversion on the fly, the W9971CF
provides high-quality video playback in 1024 × 768 256-color mode with only 1 MByte of DRAM.
The W9971CF integrates a high quality NTSC/PAL TV encoder to directly interface to TV sets. It
allows an NTSC/PAL TV to be used as the primary or secondary display for Windows-based and
video playback applications. The TV output capabilities are required for Microsoft Entertainment PC
97 designs that do not come bundled with a VGA monitor. These capabilities provide a more
realistic game, video, and multimedia experience for users who use large-screen TVs.
The flexible display memory interface design of the W9971CF allows system designers to select
various types of DRAMs, including 128K × 8, 128K × 16, 256K × 4, 256K × 8, and 256K × 16. These
DRAMs may be used in either fast page or extended data out (EDO) modes.
The W9971CF supports a glueless interface with the 32-bit PCI Local Bus. Green PC power
management is supported via VESA Display Power Management Signaling (DPMS) and power-
down of the on-chip RAMDAC and clock synthesizers. VESA DDC1 and DDC2 smart monitor
control is also supported.
