NOTE:
H1027 has input common mode choke on pins 6-7 and pins 19-20.
H1028 does not have the additional choke.
Dual Port Solutions:
The H1027NL, H1028NL, and H1049NL, are designed to support two RJ-45 connectors. The H1027NL and the H1028NL have the same
pinout. The H1027NL has an additional common mode choke on both transmit channels. The H1049NL offers a different pinout for design flexibility.
