The BCM7501 is part of Broadcom’s family of video display products,

and is a full rate, single link, DVI 1.0-compliant transmitter with HDCP

content protection. The BCM7501 transmits digital video from a digital

host such as a PC graphics card, set-top box, or DVD to a display such

as an HDTV, flat panel display, or digital CRT. The DVI interface is

uncompressed, low-cost, and digitally protected, making it ideal for

Consumer Electronics (CE) applications.

The BCM7501 transmits up to 165 Mpps of true color (24 bits/pixel)

video supporting resolutions from VGA (640 x 480) to UXGA (1600 x

1200). This bandwidth supports all television formats (including HDTV)

and does not require compression, which can cause loss in image quality.

The state-of-the-art, on-chip Phase Locked Loop (PLL) provides high-

frequency, low-jitter clock synthesis allowing full resolution, quality,

and performance.

The BCM7501 implements content protection of the TMDS link as

described by the HDCP system specification (Digital Content Protection

LLC at www.digital-cp.com). This feature allows for transmission of

high-quality digital video, while satisfying the most stringent MPAA

requirements and paving the way for Hollywood studios to release their

highest resolution content. HDCP uses keys in both ends of a DVI link

to authenticate and encrypt/decrypt the data stream, providing a secure,

physical link between the transmitter and receiver. The BCM7501

transmitter utilizes a unique method of handling HDCP keys that

provides maximum security and reduces overall system cost.

Designed by the world’s leader in communications System-on-a-Chip

circuits, the BCM7501 is a robust, highly-integrated device implemented

in an advanced .18µ process. The BCM7501 provides a secure, high-

bandwidth digital interface for current and next-generation high-

resolution products.
