GENERAL DESCRIPTION
The AD9985A 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 300
MHz support resolutions up to SXGA (1280 × 1024 at 75 Hz).
The AD9985A includes a 140 MHz triple ADC with internal
1.25 V reference, a PLL, and programmable gain, offset, and
clamp control. The user provides only a 3.3 V power supply,
analog input, and horizontal sync (Hsync) and Coast signals.
Three-state CMOS outputs can be powered from 2.5 V to 3.3 V.
The AD9985A’s on-chip PLL generates a pixel clock from the
Hsync input. Pixel clock output frequencies range from 12 MHz
to 140 MHz. PLL clock jitter is 500 ps p-p typical at 140 MSPS.
When the Coast signal is presented, the PLL maintains its
output frequency in the absence of Hsync. A sampling phase
adjustment is provided. Data, Hsync, and clock output phase
relationships are maintained. The AD9985A also offers full sync
processing for composite sync and sync-on-green applications.
A clamp signal is generated internally or can be provided by the
user through the CLAMP input pin. This interface is fully
programmable via a 2-wire serial interface.
Fabricated in an advanced CMOS process, the AD9985A is
provided in a space-saving 80-lead LQFP surface-mount
Pb-free plastic package, and is specified over the –40°C to
+85°C temperature range.
