MaxLinear SP338 | Demoboard SP338EER1-0A-EB

Description

This user’s manual is for the SP338/SP339 evaluation board. The SP338 and SP339 are pin compatible devices and are both offered in the 40-pin QFN package. The primary difference is that the SP339 only has 4modes of operation (2 mode control pins) while the SP338 has 8 modes of operation (3 mode control pins).Table 1 shows the different devices and packages that this evaluation board supports, and the corresponding ordering part numbers for each.In addition to the SP338/SP339, there is an Exar XR21B1411 1-ch USB UART on this evaluation board. When shipped from the factory, the SW3 and SW4 switches are off. Therefore, the SP338/SP339 is isolated fromboth the XR21B1411 and the DB9 connector. To enable the connections between the XR21B1411 and the SP338/SP339, place all switches on SW3 in the ON position. To enable the connections between the SP338/ SP339 and the DB9 connector, place all switches on SW4 to the ON position. All SP338/SP339 signals are accessible from the test points on the board. The test points are shown in each figure showing the modes.
