GENERAL DESCRIPTION

The ADV7525 is an 80 MHz, high definition multimedia

interface (HDMI®) transmitter with expanded CEC buffer. It

supports HDTV formats up to 1080i and computer graphic

resolutions up to XGA at 75 Hz.

With the inclusion of embedded HDCP keys, the ADV7525

allows the secure transmission of protected content, as specified

by the HDCP 1.3 protocol.

The ADV7525 supports both SPDIF and 8-channel I

Its high fidelity 8-channel I

sampling rate. The SPDIF can carry stereo LPCM audio or

compressed audio, including Dolby® Digital and DTS®.

The ADV7525 helps to reduce system design complexity and

cost by incorporating such features as an I

reading and 5 V tolerance on the I

Fabricated in an advanced CMOS process, the ADV7525 is

available in a space-saving, 64-ball, WLCSP surface-mount

package. This package is RoHS compliant and specified to

operate from −25°C to +85°C
