The BCM7520 is inter-operates reliably with the BCM7501 and other DVI a high performance and robust interface for computing and transmitters. entertainment systems alike. The receiver provides a secure, ® Transition Minimized Differential Signaling (TMDS ) link HDCP encrypts data, allowing for the transmission of high- between a digital monitor or TV and any source of digital video quality, uncompressed digital video while satisfying MPAA content, such as a DVD player, digital set-top box or PC graphics security requirements. HDCP uses keys in both the transmitter card. and receiver to authenticate and encrypt/decrypt the data stream, providing a secure, physical link between the transmitter and The BCM7520 receives up to 165 Megapixels per second receiver. The BCM7520 utilizes a unique method of handling (Mpps) of true color, 24-bit video data supporting resolutions HDCP keys that provides maximum security without from VGA (640 x 480) to UXGA (1600 x 1200). This bandwidth compromising testability. supports all television formats, including HDTV, without requiring compression which can degrade image quality. For Designed by the world’s leader in communications system-on-a- very high resolution displays or high refresh rates, the BCM7520 chip circuits, the BCM7520 is a secure, robust, .18m DVI functions as a dual link receiver when paired with an additional receiver, ideal for current and next-generation high-resolution BCM7520. Dual link capability supports resolutions at UXGA display products. and above. The BCM7520 includes integrated line termination to reduce communication impairments such as reflection, noise and ringing that can occur over the DVI cable. Precise termination, low-jitter PLLs and 6x oversampling enable the BCM7520 to provide exceptionally accurate data recovery.
