BENEFITS
Bel’s 79201 and 79202 are signal coupling transformers for use with the full range of Intellon HomePlug™ 1.0 compliant
chipsets. These transformers provide a low cost high quality solution to simplify the implementation of HomePlug products.
The couplers are fully compatible with APC79101-x analog front end modules for maximum design flexibility, as well as the
latest 79102xx-x modules incorporating the INT51X1 chipset for more highly integrated systems.
A single 79201 coupler may be used where the chipset is co-located with the equipment power supply such as a mains
powered desktop unit or wallplug modem. With the addition of a 79202 coupler, the chipset may be located in equipment fed
from a DC line cord wall adapter.

Notes
1. A suitable MOV transient suppressor should be chosen depending on the designed AC supply voltage of the product. We recommend a
240V part for 115VAC operation or a 375V part for 230-250V application.
2. High frequency isolation may be required if power supply circuits with high input capacitance, such as switch mode designs, are used.
Inductors for this purpose should be minimum 25uH and have good performance in the 4 to 21 MHz band.
