GENERAL DESCRIPTION

The ADV7520NK is an 80 MHz, high definition multimedia

interface (HDMI) v.1.3 transmitter. It supports HDTV formats

up to 1080i and 720p, and computer graphic resolutions up to

XGA (1024 x 768 @ 75 Hz). The ADV7520NK allows the secure

transmission of protected content as specified by the HDCP

v1.3 protocol when HDCP keys are implemented externally.
