Analog Flat Panel Interface
GENERAL DESCRIPTION
The AD9884A is a complete 8-bit 140 MSPS monolithic analog
interface optimized for capturing RGB graphics signals from
personal computers and workstations. Its 140 MSPS encode
rate capability and full-power analog bandwidth of 500 MHz
supports display resolutions of up to 1280
×
1024 (SXGA) at
75 Hz with sufficient input bandwidth to accurately acquire and
digitize each pixel.
To minimize system cost and power dissipation, the AD9884A
includes an internal +1.25 V reference, PLL to generate a pixel
clock from HSYNC, and programmable gain, offset and clamp
circuits. The user provides only a +3.3 V power supply, analog
input, and HSYNC signals. Three-state CMOS outputs may be
powered by a supply between 2.5 V and 3.3 V.
The AD9884A’s on-chip PLL generates a pixel clock from the
HSYNC input. Pixel clock output frequencies range from

20 MHz to 140 MHz. PLL clock jitter is typically 400 ps p-p
relative to the input reference. When the COAST signal is pre-
sented, the PLL maintains its output frequency in the absence
of HSYNC. A 32-step sampling phase adjustment is provided.
Data, HSYNC and Data Clock output phase relationships are
always maintained. The PLL can be disabled and an external
clock input provided as the pixel clock.
A clamp signal is generated internally or may be provided by the
user through the CLAMP input pin. This device is fully program-
mable via a two-wire serial port.
Fabricated in an advanced CMOS process, the AD9884A is
provided in a space-saving 128-lead MQFP surface mount plas-
tic package and is specified over a 0
°
C to +70

range.
