Hot-selling and scarce AD9883AKST-140 Analog Interface for Flat Panel Displays LQFP-80 spot stock

Product Descriptions

The AD9883A is a complete 8-bit, 140 MSPS, monolithic analoginterface optimized for capturing RGB graphics signals frompersonal computers and workstations . Its 140 MSPS encoderate capability and full power analog bandwidth of 300 MHzsupports resolutions up to SXGA (1280 × 1024 at 75 Hz).

The AD9883A includes a 140 MHz triple ADC with internal1.25 V reference, a PLL, and programmable gain, offset, andclamp control . The user provides only a 3.3 V power supply,analog input, and Hsync and COAST signals . Three-stateCMOS outputs may be powered from 2.5 V to 3.3 V .

The AD9883A’s on-chip PLL generates a pixel clock from theHsync 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 itsoutput frequency in the absence of Hsync . A sampling phaseadjustment is provided . Data, Hsync, and clock output phaserelationships are maintained . The AD9883A also offers full syncprocessing for composite sync and sync-on-green applications .

A clamp signal is generated internally or may be provided bythe user through the CLAMP input pin . This interface is fullyprogrammable via a 2-wire serial interface .

Fabricated in an advanced CMOS process, the AD9883A is provided in a space-saving 80-lead LQFP surface-mount plastic packageand is specified over the –40°C to +85°C temperature range .
