    Single Twisted Pair Power Over Datalines (PoDL) Common Mode Chokes

    by Pulse Networking Team

    Pulse releases the AE3003 100Base-T1 PoDL common mode choke(CMC) for automotive Ethernet applications requiring power over the datalines on a single twisted pair wire. The AE3003 is the first 300mA single twisted pair PoDL part released to production. The AE3003 supports PoDL classes 0, 1, 2, 3, and 6, see PoDL class table below.

    PoDL Class Table

    This technology is important to designers because it allows you to send power and data over a single twisted pair wire. This reduces the need for a second twisted pair wire to power an end device and thus reduces the overall weight and cost of cabling in the car. Pulse is in the process of also releasing AE3005 a 350mA PoDL CMC and AE3006 a 450mA PoDL CMC. Pulse’s parts are designed to operate from -40C to +125C, have high reliability, high volume manufacturing, long term manufacturing support, and meet AEC-Q200 requirements. Pulse parts are built in an IATF 16949:2016 factory and PPAP documentation is available.
