GENERAL DESCRIPTION
The AD9887A offers an analog interface receiver and a digital
visual interface (DVI) receiver integrated on a single chip,
supports high bandwidth digital content protection (HDCP),
and is software and pin-to-pin compatible with the AD9887.
Analog Interface
The complete 8-bit, 170 MSPS, monolithic analog interface is
optimized for capturing RGB graphics signals from personal
computers and workstations. Its 170 MSPS encode rate capability
and full-power analog bandwidth of 330 MHz support resolutions
of up to 1600 × 1200 (UXGA) at 60 Hz. The interface includes
a 170 MHz triple ADC with internal 1.25 V reference; a phase-
locked loop (PLL); and programmable gain, offset, and clamp
controls. The user provides only a 3.3 V power supply, analog
input, and Hsync. Three-state CMOS outputs can be powered
from 2.5 V to 3.3 V. The analog interface also offers full sync
processing for composite sync and sync-on-green (SOG) appli-
cations. The AD9887A on-chip PLL generates a pixel clock from
Hsync with output frequencies ranging from 12 MHz to 170 MHz.
PLL clock jitter is typically 500 ps p-p at 170 MSPS.

Digital Interface
The AD9887A contains a DVI 1.0-compatible receiver and
supports resolutions up to 1600 × 1200 (UXGA) at 60 Hz. The
receiver operates with true color (24-bit) panels in one or two
pixel(s) per clock mode and features an intrapair skew tolerance
of up to one full clock cycle. With the inclusion of HDCP,
displays can receive encrypted video content. The AD9887A
allows for authentication of a video receiver, decryption of encoded
data at the receiver, and renewability of authentication during
transmission, as specified by the HDCP v1.0 protocol. Fabricated
in an advanced CMOS process, the AD9887A is provided in a
160-lead, surface-mount, plastic MQFP and is specified over the
0°C to 70°C temperature range. The AD9887A is also available
in an RoHS compliant package.
