GENERAL DESCRIPTION

OUTB

The AD9886 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 330 MHz

supports resolutions up to SXGA (1280 × 1024 at 75 Hz).

GENERATION

For ease of design and to minimize cost, the AD9886 is a fully

integrated interface solution for FPDs. The AD9886 includes a

140 MHz triple ADC with internal 1.25 V reference, PLL to

generate a pixel clock from an HSYNC, and programmable

gain, offset, and clamp control. The user provides only a 3.3 V

power supply, analog input, and an HSYNC signal. Three-state

CMOS outputs may be powered from 2.5 V to 3.3 V.

POWER MANAGEMENT

The AD9886’s on-chip PLL generates a pixel clock from an

HSYNC. 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 PLL can be disabled and an

external clock input provided as the pixel clock. The AD9886

also offers full sync processing for composite sync and sync-on-

green applications.

A clamp signal is generated internally or may be provided by the

user through the CLAMP input pin. This interface is fully pro-

grammable via a 2-wire serial interface.
