Description
Building on innovative, market-leading technology, Cirrus
Logic presents the most complete DVD processor solu-
tion available: CS98100. The CS98100 provides the high-
performance typical of Cirrus Logic integrated circuits,
and on-chip integration that allows for seamless integra-
tion of functions. Among the integrated functions in this
system-on-chip architecture is
a high quality NTSC/PAL
encoder with a triple 10-bit video DAC, allowing for a sig-
nificant decrease in system cost.
Not only is the CS98100 equipped with an intuitive on-
screen display and user interface, but the CS98100 also
offers progressive output, DTS decoding, HDCD sup-
port, and MP3 plus WMA decoding. Other advanced
features include karaoke down-mix. The low cost ex-
tended feature set makes the CS98100 ideal for both
low-end and high-end system manufacturers.
