(1)

The actual voltage must be determined at device power-up, and not be changed dynamically during run-time.

(2)

Applies to "tape and reel" part number counterparts as well. For more information, see Section 2.7 , Device and Development-Support

Tool Nomenclature.

(3)

Oscillator 1.8 V power supply (MXVDD) can be connected to the same 1.8 V power supply as DVDDR2.

(4)

Oscillator ground (MXVSS) must be kept separate from other grounds and connected directly to the crystal load capacitor ground.

(5)

DDR_VREF is expected to equal 0.5DVDDR2 of the transmitting device and to track variations in the DVDDR2.

(6)

In the absence of a heat sink or direct thermal attachment on the top of the device, use the following formula to determine the device

junction temperature: TJ = TC + (Power x PsiJT). Power and TC can be measured by the user. Section 7.1 , Thermal Data for ZWT and

Section 7.2 , Thermal Data for ZDU provide the junction-to-package top (PSIJT) value based on airflow in the system. In the presence of

a heat sink or direct thermal attachment on the top of the device, additional calculations and considerations must be taken into account.

For more detailed information on thermal considerations, measurements, and calculations, see the Thermal Considerations for the

DM64xx, DM64x, and C6000 Devices Application Report (literature number SPRAAL9).

(7)

Applications must meet both the Operating Junction Temperature and Operating Ambient Temperature requirements. For more detailed

information on thermal considerations, measurements, and calculations, see the Thermal Considerations for the DM64xx, DM64x, and

C6000 Devices Application Report (literature number SPRAAL9).
