The AD9387NK supports both S/PDIF and 8-channel I2S audio.
Its high fidelity, 8-channel I2S can transmit either stereo or 7.1
surround audio at 192 kHz. The S/PDIF can carry stereo LPCM
audio or compressed audio, including Dolby® Digital, DTS®,
and THX®.
HDMI repeater/splitter
The AD9387NK helps reduce system design complexity and cost
by incorporating such features as an internal MPU for HDCP
operations, an I2C master for EDID reading, a single 1.8 V power
supply, and 5 V tolerance on the I2C and hot plug detect pins.
GENERAL DESCRIPTION
The AD9387NK is an 80 MHz, high definition multimedia
interface (HDMI) v.1.3 transmitter. It supports HDTV formats
up to 720p and 1080i and computer graphic resolutions up to
XGA (1024 × 768 @ 75Hz). With the inclusion of HDCP, the
AD9387NK allows the secure transmission of protected content,
as specified by the HDCP v.1.1 protocol.
Fabricated in an advanced CMOS process, the AD9387NK
is available in a space saving, 76-ball CSP_BGA or 64-lead LFCSP
surface-mount package. Both packages are available as Pb-free
parts and are specified from −25°C to +85°C.
