VSC8531BB1G Description
The VSC8531BB1G is the latest design to join the licensed "BeagleBoard Compatible" family. It is similar to the Beaglebone Black (Rev C) but with some additional features added.


 * Upgraded memory to 1GB of DDR3
 * Upgraded eMMC to 4GB
 * Replaced FE PHY with the Microsemi VSC8531XMW RGMII/RMII Single Port Gigabit Copper Ethernet PHY (and supporting LDOs for the required 1.0V and 2.5V rails)
 * Replaced off-the-shelf integrated magnetics RJ-45 jack with the specially designed for Microsemi line of SimpliPHYTM, VeriTimeTM, and IntellisecTM PHYs, Open-Source Hardware compliant HALO Electronics TG111-MSC13LF 8-core transformer, and a quality RJ-45 jack with dual LEDs.

In addition to being FCC Class B, CE, RoHS & REACH certified just like the BeagleBone Black is, this 6-layer development board & evaluation tool, is capable of passing UNH IOL GbE, Fast Ethernet, as well as 10Base-T/Te certification. For anyone out that has attempted to take their end-product through this compliance testing, they will be the first to tell you that it is not straight forward. The layout and magnetic selection is critical to ensuring success.

The VSC8531BB1G can help to reduce the customer's TTM as well as their development costs.
