| FFF Compatibility | Identical footprint, package (16-WQFN 4x4), and pinout.Identical physical dimensions, mounting style, and materials.Identical electrical characteristics, data rates (up to 2.97 Gbps), and 2.5V power supply. | Pinout is physically compatible with the footprint, but some configuration pins require circuit changes and the supply pins must be routed to 3.3V instead of 2.5V.Identical 16-pin 4x4mm QFN package size, pitch, and SMD mounting style.Operates on a 3.3V supply instead of the 2.5V supply required by the LMH0394, and uses slightly different control logic and external integration capacitor values. | ||
 AI Summary | LMH0394SQE/NOPB by Texas Instruments: Amplifier Interface 16-WQFN (4x4). | This is a direct sibling within the LMH0394 family, offering identical physical and electrical specifications. The only difference is the packaging configuration, as the 'SQ' suffix denotes a larger tape-and-reel quantity (1000 units) compared to the 'SQE' suffix (250 units).
| The GS3440-INTE3 is a high-performance 3G-SDI adaptive cable equalizer. While it fits on the same physical footprint, it requires a 3.3V power supply instead of 2.5V, and minor configuration/passive component adjustments are needed for full functional replacement.
