700 mOhm 4PDT analog switch for networking hardware
The NX3DV2567HR,115 is a 4PDT analog switch from NXP, built for routing signals in networking equipment. Its 700 mOhm on-resistance keeps insertion loss low, and the 160 MHz -3dB bandwidth means it can pass Ethernet or video signals without rolling off the edges.
700 mOhm max on-resistance keeps insertion loss low. The 160 MHz -3dB bandwidth is the frequency where the signal drops by half; below that the switch behaves like a near-transparent pass-through. If you are switching 1000BASE-T or LVDS, this part keeps the eye diagram open. The 4PDT configuration gives you four independent poles, each with two throws — enough to swap a differential pair plus a shield or control line in one package. Single-channel design means one switch cell per package; if the board needs multiple switched paths, you stack several devices.
Temperature range and package — where it survives
The 16-HXQFN package measures 3x3 mm with an exposed pad that pulls heat into the PCB copper — critical when the switch is passing continuous signals near the top of the temperature range.
