5 Application Example Schematics
In the following two examples connection of a Physical Ethernet chip and a USB 2.0 chip to the Core Module are
provided.
5.1 Schematic Example for Connecting a Physical Ethernet Chip
Since the ADSP-BF537 Blackfin Chip from Analog Devices already has Ethernet functionality only a physical Ethernet
chip needs to be connected to the TCM-BF537 Core Module in order to make use of this feature.
