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.

surround audio at 192 kHz. The S/PDIF can carry stereo LPCM

audio or compressed audio, including Dolby® Digital, DTS®,

and THX®.

The AD9387NK helps reduce system design complexity and cost

by incorporating such features as an internal MPU for HDCP

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.
