+description: |
+ The IT6505 is a high-performance DisplayPort 1.1a transmitter,
+fully compliant with DisplayPort 1.1a, HDCP 1.3 specifications.
+The IT6505 supports color depth of up to 36 bits (12 bits/color)
+and ensures robust transmission of high-quality uncompressed video
+content, along with uncompressed and compressed digital audio content.
+
+ Aside from the various video output formats supported, the IT6505
+also encodes and transmits up to 8 channels of I2S digital audio,
+with sampling rate up to 192kHz and sample size up to 24 bits.
+In addition, an S/PDIF input port takes in compressed audio of up to
+192kHz frame rate.
+
+ Each IT6505 chip comes preprogrammed with an unique HDCP key,
+in compliance with the HDCP 1.3 standard so as to provide secure
+transmission of high-definition content. Users of the IT6505 need not
+purchase any HDCP keys or ROMs.
