GENERAL DESCRIPTION
The ADV7526 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 inclusion of embedded HDCP keys, the ADV7526
allows the secure transmission of protected content, as specified
by the HDCP 1.3 protocol.
The ADV7526 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 ADV7526 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 ADV7526 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.
