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

pulse-code modulation (LPCM) audio or compressed audio,

including Dolby® Digital and DTS®.

The AD9387NK helps reduce system design complexity and cost

by incorporating such features as an internal microprocessor

for high-bandwidth digital content protection (HDCP) opera-

(EDID) reading, a single 1.8 V power supply, and 5 V tolerance

and resources, see the Applications Information section.

Fabricated in an advanced CMOS process, the AD9387NK

is available in a space saving, 76-ball CSP_BGA. The package is

RoHS compliant and is specified from −25°C to +90°C

operation.
