4.3 0-Ω Resistors

The 0-Ω resistor R2 is used to connect the programming voltage to the PGA450-Q1 device that is soldered to the PCB. This resistor is not populated on the PCB. The soldered device has had the OTP programmed for DEVRAM usage.

Reference Install Function
R2 DNP The VP_OTP pin of the device does not have OTP programming voltage.

Although they are installed to default settings in the factory, it is recommended that the user verify that the jumpers and 0-Ω resistors are installed to their default settings before powering on the EVM.
