4.1 Jumpers

Table 1 shows the function of each specific jumper setting on the EVM.

Table 1. Jumpers

Reference Jumper Setting Function
VPWR:VOTP Closed VP_OTP power supply input on the PGA450-Q1 device is connected to the 8-V voltage supply on the EVM.
Open VP_OTP power supply input on the PGA450-Q1 device is not connected to the 8-V voltage supply on the EVM.
VPWR:VLIN Closed VPWR is connected to V_LIN, which is the LIN bus voltage.
Open VPWR is not connected to V_LIN, which is the LIN bus voltage.
JP3 Closed The secondary of the transformer on the EVM is connected to the PGA450-Q1 device on the EVM.
Open The secondary of the transformer on the EVM is not connected to the PGA450-Q1 device on the EVM.
JP4 Closed The transformer primary top terminal is connected to the OUTA pin on the PGA450-Q1 device, for push-pull configuration.(1)
Open The transformer primary top terminal is not connected to the OUTA pin on the PGA450-Q1 device.
JP5 Closed The transformer primary top terminal is connected to the VREG pin on the PGA450-Q1 device, for single-ended configuration.
Open The transformer primary top terminal is not connected to the VREG pin on the PGA450-Q1 device.
(1) The transformer provided with the EVM is push-pull. When using the single-ended configuration, JP4 must be disconnected and JP5 must be closed
