The Texas Instruments DS90LV048ATMX is a quad-channel LVDS receiver designed to convert low-voltage differential signaling back to CMOS logic levels. It handles a per-channel data rate of 400 Mbps, making it suitable for high-speed serial links in video interfaces, backplane data distribution, and cable-extension applications where noise immunity and low EMI matter.
At 400 Mbps each channel, the receiver can clock a 200 MHz DDR data stream or four independent 400 Mbps serial lines. The LVDS common-mode range of typically 0.2 V to 2.2 V gives margin against ground shifts between driver and receiver — a common headache in multi-board systems. The 16-SOIC narrow-body package (3.90 mm width) keeps the per-channel footprint small, but the 0.154-inch body height means it sits low enough for mezzanine-card clearance. If you are replacing an older PECL receiver, the 3.3 V single-supply rail simplifies the power tree.
The DS90LV048ATMX is officially marked obsolete.
Pin-compatible replacement search
Because this part is obsolete, the buyer's first question is usually the pin-compatible drop-in. The DS90LV048 family shares the same 16-SOIC footprint and pinout across its speed and temperature variants, so a current-production sibling like the DS90LV048A (if still active) or the DS90LV048Q (automotive-grade) may fit without a board spin.
