CX25874/CX25875

Adaptive Flicker Filtering

The CX25874 and CX25875 include Conexant’s unique

adaptive flicker-filtering capability. With this feature, the

optimal amount of flicker filtering for a given application

is automatically determined by the characteristics of the

pixel content. Now both an Excel spreadsheet and DVD

movie can look great at the same time. Consumers

do not have to manually adjust the amount of flicker

filtering as they switch from applications requiring

significant flicker filtering (e.g., text-intensive applications

like an Excel spreadsheet) to those requiring little or no

flicker filtering (e.g., a DVD movie).

International Support

The CX25874 and CX25875 provide the most complete

support for products with TV-out functionality shipped

to the U.S. and international markets. The CX25874

and CX25875 support SCART and Wide Screen

Signaling (WSS) 16:9 aspect ratio. The international

standards supported include NTSC (North America,

Taiwan, Japan), PAL-B, D, G, H, I (Europe, Asia), PAL-M

(Brazil), PAL-N (Paraguay), PAL-Nc (Argentina), PAL-60,

ECAM-D, K, K1 (Russia), SECAM-B, G, H (Middle East)

and SECAM-L (France).

Pixel Input Formats and Timing

The CX25874 and CX25875 convert a wide range

of input formats to television video formats.The input

resolution can be non-interlaced with an active

resolution of 320 x 200 to 1024 x 768 or interlaced

such as CCIR601, CCIR656 and VESA VIP. Conexant

is the only provider of video encoders that have the

flexibility to offer any resolution in this range with

so many input and output format options.This includes

the exact resolution to display DVD movies in either

NTSC or PAL formats.
