ADV7521NK:  Low-Power HDMI/DVI Transmitter with Consumer Electronic Control (CEC)

Product Description

The ADV7521NK is an 80 MHz, high definition multimedia interface (HDMI™) v.1.3 transmitter. It supports HDTV formats up to 1080i and 720p, and computer graphic resolutions up to XGA (1024 × 768 @ 75 Hz).

The ADV7521NK supports both S/PDIF and 2-channel I2S audio. Its high fidelity 2-channel I2S can transmit stereo at up to 192 kHz sampling rate. The S/PDIF can carry stereo LPCM audio or compressed audio including Dolby® Digital and DTS®.

The ADV7521NK helps to reduce system design complexity and cost by incorporating such features as an I2C master for EDID reading, a single 1.8V power supply and 5 V tolerance on I2C and hot plug detect pins.

Fabricated in an advanced CMOS process, the ADV7521NK 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.
