a high-performance, cost-effective, basic analog television capture, or can be
used as the base for more complex multiple tuner configurations. The device
can support capture of two simultaneous digital television transport streams,
or a combination of analog and digital capture. The device can be used in
conjunction with Conexant’s tuners and demodulators to create hybrid tuner
cards that support ATSC, DVB-S, DVB-S2, and DVB-T content.
and Automatic Gain Control (AGC). Quality video is accomplished by using
a two dimensional adaptive comb filter for NTSC and PAL video for improved
saturation, and contrast controls.
For high-quality audio, Conexant provides ADCs for stereo audio capture. A
minimum of 16-bit audio resolution through the entire audio data path ensures
the sigma-delta ADCs, or an external serial audio source. The audio path includes
an automatic volume control function and two assignable stereo processing units
for control of volume, three-band equalization, and balance. The level of audio
and video integration provided by the CX23885 removes the need for additional
chips. It also reduces the overall Bill of Materials (BOM) for the system developer,
without compromising audio and video performance. To enable faster time
to market, Conexant offers multiple CX23885 PCI Express and ExpressCard
reference designs. All of the reference designs include schematics, layout files,
and evaluation boards with production-ready device drivers.
Conexant’s fourth-generation device represents another landmark in the
company’s video innovation timeline. Additional pioneering developments

most widely deployed MPEG audio/video encoder, and launched the first
