GENERAL DESCRIPTION
The ADV7541 is a 150 MHz, high definition multimedia
interface (HDMI®) transmitter. It supports HDTV formats up to
1080p and computer graphic resolutions up to SXGA at 75 Hz.
With the optional inclusion of embedded HDCP keys, the
ADV7541 allows the secure transmission of protected content,
as specified by the HDCP 1.3 protocol.
The ADV7541 supports both S/PDIF and 2-channel I2S audio.
Its high fidelity, 2-channel I2S can transmit stereo at up to a
192 kHz sampling rate. The S/PDIF can carry stereo LPCM
audio or compressed audio including Dolby® Digital and DTS®.
The ADV7541 helps to reduce system design complexity and
cost by incorporating such features as an I2C master for EDID
reading and 5 V tolerance on I2C and Hot Plug™ detect pins.
Fabricated in an advanced CMOS process, the ADV7541 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.
