IRDM982 Series
Recommended Operating Conditions
For proper operation, the device should be used within the recommended conditions. All voltage parameters are absolute
voltages referenced to VSS unless otherwise stated in the table.
The input/output logic timing diagram is shown in Fig. 1.
The VS and VSS offset rating are tested with all supplies biased at a 15 V (VCC) differential / 3.3V (VDD).
Power up and down sequences are not dependent on the order of VCC, DCBUS, and VSP for proper operation to start or
stop.

Information section of this datasheet for more details.
1) Guarantee by design, not tested at manufacturing
2) Carrier Frequency is calculated by the following.
