The AD9388A is a high quality, single-chip graphics digitizer with an integrated 2:1 multiplexed HDMI® receiver.
The AD9388A contains one main component processor (CP) that processes YPrPb and RGB component formats, including RGB graphics. The CP also processes the video signals from the HDMI receiver. The AD9388A can keep the HDCP link between an HDMI source and the selected HDMI port active in analog mode operation. This allows for fast switching between the analog and HDMI modes.
The AD9388A supports the decoding of a component RGB or YPrPb video signal into a digital YCrCb or RGB pixel output stream. The support for component video includes 525i, 625i, 525p, 625p, 720p, 1080i, 1080p, and 1250i standards, as well as many other HD and SMPTE standards.
Graphics digitization is also supported by the AD9388A. The AD9388A is capable of digitizing RGB graphics signals from VGA to UXGA rates and converting them into a digital RGB or YCrCb pixel output stream.
The AD9388A incorporates a dual input HDMI-compatible receiver that supports HDTV formats up to 1080p and display resolutions up to UXGA (1600 × 1200 at 60 Hz). The reception of encrypted video is possible with the inclusion of HDCP. In addition, the inclusion of adaptive equalization ensures robust operation of the interface with cable lengths up to 30 meters. The HDMI receiver has advanced audio functionality, such as a mute controller that prevents audible extraneous noise in the audio output.
Derivative parts of the AD9388A are available; AD9388ABSTZ-A5 is composed of one analog and one digital input. To facilitate professional applications, where HDCP processing and decryption are not required, the AD9388ABSTZ-5P derivative is available. This allows users who are not HDCP adopters to purchase the AD9388A (see the Ordering Guide section for details on these derivative parts).
Fabricated in an advanced CMOS process, the AD9388A is available in a space-saving, 144-lead, surface-mount, RoHS-compliant, plastic LQFP and is specified over the −40°C to +85°C temperature range.
