|
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.
