GENERAL DESCRIPTION
The ADV7528 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.
The ADV7528 supports x.v.Color™ (gamut metadata) for a
wider color gamut.
The ADV7528 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 ADV7528 helps to reduce system design complexity and
cost by incorporating features such 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 ADV7528 is
available in a space-saving, surface-mount, 49-ball WLCSP
package. This package is RoHS compliant and specified to
operate from −25°C to +85°C.
