Hardware Configuration
This section provides information on the PCM4222EVM hardware configuration, including power supplies
and switch settings. Evaluation module handling information and absolute operating conditions are also
provided.
CAUTION
Failure to observe proper ESD handling procedures may result in damage to
PCM4222EVM components.
Many of the components used in the assembly of the evaluation module are susceptible to damage by
electrostatic discharge (ESD). Customers are advised to observe proper ESD handling procedure when
unpacking and handling the EVM. All handling should be performed at an approved ESD workstation or
test bench while wearing an appropriate grounding device. Failure to observe ESD handling procedures
may result in damage to EVM components.
CAUTION
Exceeding the absolute operating conditions may result in improper operation
or damage to the evaluation module and/or the equipment connected to it.
Table 1 summarizes the critical data points for the PCM4222EVM absolute operating conditions.
