6 / 34 page Si57x-EVB 6 Rev. 0.2 1.5.2. Jumpers There are eight jumper locations on the Si57x-EVB as listed in Table 3. (The reference designations J4-J5 and J16-17 are assigned to other connector types.) The default or pre-loaded jumpers are shown in Figure 3. Table 3. Si57x-EVB Jumpers Reference Designation Configuration Signals Default (Pre-loaded) Jumper Installation J1 1X2 Bypasses U3 level translator. Connects signal MCU_SDA to signal 57x_SDA. Installed Supports DUT_VDD = 2.5 or 3.3 V nominal. J2 1X2 Bypasses U3 level translator. Connects signal MCU_SCL to signal 57x_SCL. Installed Supports DUT_VDD = 2.5 or 3.3 V nominal. J3 1X2 Disables OE active low signal. See "1.7. Si57x/598/599 Digital Control Signals" on page 8. Not installed J6 1X3 Selects voltage regulator output supplying DUT_VDD. See "1.2. Power Supply" on page 3 and Table 1 on page 3. Installed in 3.3 V position. Ready for MCU control. (Default voltage selection is 1.8 V if no jumper is installed.) J7 1X2 Reset Not installed J8 1X2 57x SDA test pins only. Not installed J9 1X2 Disables OE active high signal. See “1.7. Si57x/598/599 Digital Control Signals” . Not installed J10 1X2 57x SCL test pins only. Not installed J11 2X3 Disables U3 level translator. Installed Supports DUT_VDD = 2.5 or 3.3 V nominal. |
