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 I2S audio.
Its high fidelity 8-channel I2S can transmit stereo up to a 192 kHz
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 I2C master for EDID
reading and 5 V tolerance on the I2C and Hot Plug™ detect pins.
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
