GENERAL DESCRIPTION
The ADV7524A is a 150 MHz, High-Definition Multimedia
Interface (HDMI®) transmitter with expanded CEC buffer. It
supports HDTV formats up to 1080p and computer graphic
resolutions up to SXGA at 75 Hz.
With the optional inclusion of embedded HDCP keys, the
ADV7524A allows the secure transmission of protected content,
as specified by the HDCP 1.3 protocol.
The ADV7524A supports 3D video and extended colorimetry.
The ADV7524A supports both S/PDIF and 2-channel I2S audio.
Its high fidelity, 2-channel I2S can transmit stereo up to a 192 kHz
sampling rate. The S/PDIF can carry stereo LPCM audio or
compressed audio including Dolby® digital and DTS®.
The ADV7524A 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 ADV7524A is
available in a space saving, 49-ball, WLCSP surface-mount
package. This package is RoHS compliant and specified to
operate from −25°C to +85°C.
