(DVI) Digital Video Transmitter

CX25894/5/6

DVI Compliancy and Dual Channel Support

Numerous Applications

Conexant’s broadband communications portfolio includes a

comprehensive suite of semiconductor solutions that enable the

digital home and information network. Compliant with the Digital

Visual Interface (DVI) industry specification, the CX25894/5/6 family

of high performance, single-chip transmitters offers single or dual link

output. Supporting up to two independent concurrent channels and

two serial interfaces, this device is well suited for desktop PCs

or any application that drives digital or flat panel displays.

High-bandwidth Digital-Content Protection (HDCP) was developed to

protect digital entertainment content flowing over the DVI interface.

HDCP encrypts the transmission of digital content between the video

source or transmitter – such as a computer, DVD player or set-top box –

and the digital display, or receiver – such as a monitor, television or

projector. Once authentication is established, the transmitter encrypts

the data and sends it to the receiver for decryption.

Three versions of this DVI-Compliant transmitter are available. The

CX25895/6 accepts and sends out different resolutions and independent

content simultaneously.

CX25894

offers a single channel, single link DVI, supporting resolutions up

to 1600 x 1200, 60 Hz vertical refresh (maximum).

CX25895

adds another independent channel and supports up to two

single link 1600 x 1200 DVI outputs or a dual link output with a resolution

to 2048 x 1536. Using the CX25895, you have the flexibility to enable two

low-resolution DVI outputs or one high resolution flat panel monitor or DTV.

CX25896

builds upon the CX25895 but adds the industry standard

high definition copy protection (HDCP 1.0).

The CX25894/5/6 is packaged in an 84-pin QFN (body: 12.0 mm x 12.0

mm, pin pitch 0.40 mm). All are pin compatible.
