Table 17: Indicative power requirements
Values in Table 17 are provided for customer information only as an example of typical power
requirements. Values are characterized on samples, actual power requirements can vary depending on
FW version used, external circuitry, number of SVs tracked, signal strength, type of start as well as time,
duration and conditions of test.
For more information about power requirements, see the
AMY-6M Hardware Integration Manual

SPI timing diagrams
In order to avoid a faulty usage of the SPI, the user needs to comply with certain timing conditions. The
following signals need to be considered for timing constraints:
