Low Power HDMI/DVI Transmitter with Consumer Electronic Control (CEC)

The ADV7523A 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 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 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 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.
