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).  
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.  
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.  
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.  
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.
