Hot-selling and scarce AD9888KSZ-170 Analog Flat Panel Interface IC QFP128 spot stock

Product Descriptions

The AD9888 is a complete 8-bit, 170 MSPS,monolithic analog interface optimized for capturing RGB graphics signals from personal computers and workstations.Its 170 MSPS encode rate capability and full-power analog bandwidth of 500 MHz supports resolutions of up to 1600 × 1200 (UXGA) at 75 Hz.

For ease of design and to minimize cost, the AD9888 is a fully integrated interface solution for flat panel displays.The AD9888 includes an analog interface that has a 170 MHz triple ADC with an internal 1.25 V reference phase-locked loop (PLL)to generate a pixel clock from HSYNC and COAST; midscale clamping; and programmable gain,offset, and clamp controls.The user provides only a 3.3 V power supply, analog input, and HSYNC and COAST signals. Three-state CMOS outputs can be powered from 2.5 V to 3.3 V.

The on-chip PLL ofthe AD9888 generates a pixel clock from the HSYNC and COAST inputs. Pixel clock output frequencies range from 10 MHz to 170 MHz. PLL clock jitter is typically less than 450 ps p-p at 170 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 can be provided as the pixel clock. The AD9888 also offers full sync processing for composite sync and sync-on-green applications.
