Procurement Notes

This component is officially classified as obsolete by Analog Devices Inc., with discontinuation notifications dated February 7, 2020. Procurement must rely on remaining stock or secondary market sources. Verify part authenticity carefully due to end-of-life status. Ensure compatibility with existing design specifications before acquisition, as new manufacturing is no longer supported.

Selection Notes

Select this component only for legacy designs requiring specific 125 MSPS digital upconversion with integrated crest reduction. It is unsuitable for new development due to obsolescence. Consider alternative modern RFICs from Analog Devices for new projects. Verify voltage requirements of 1.8 V and 3.3 V against system constraints. Confirm package compatibility with the 196-CSPBGA footprint.
