With the optional inclusion of embedded HDCP keys, the
ADV7523A allows the secure transmission of protected content,
as specified by the HDCP 1.3 protocol.
The ADV7523A supports x.v.Color (gamut metadata) for a
wider color gamut.
The ADV7523A supports both S/PDIF and 2-channel I2S audio.
Its high fidelity, 2-channel I2S audio can transmit stereo up to a
192 kHz sampling rate. S/PDIF can carry stereo LPCM audio or
compressed audio, including Dolby digital and DTS.
The ADV7523A 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 ADV7523A 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.
