GENERAL DESCRIPTION

monolithic analog interface optimized for capturing

RGB graphics signals from personal computers and

workstations. Its 140 Msps encode rate capability

and

supports display resolutions of up to 1280x1024

(SXGA) at 85Hz with sufficient input bandwidth to

accurately acquire and digitize each pixel.

the CS9883 includes an internal +1.25V reference,

PLL to generate a pixel clock from HSYNC, and

programmable gain, offset and clamp circuits. The

users provide only a +3.3V power supply, analog

input, and HSYNC and COAST signals.

clock from the HSYNC and COAST inputs. Pixel

clock output frequencies range from 20MHz to

140MHz. PLL clock jitter is typically 500ps p-p. When

the COAST signal is presented, 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 CS9883 also offers full

sync processing for composite sync and sync-on-

green applications.

provided by the user through the CLAMP input pin.

This device is fully programmable via two-wire serial

port.

CS9883 is provided in a space-saving 80-lead LQFP

surface mount plastic package and is specified over

a 0 C to +70 C temperature range.
