PRODUCTION DATA

5.1 Absolute Maximum Ratings

Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

(1) All voltage values are with respect to the ground terminals (V_SS). The following required power supplies must be connected for proper DMD operation: V_DD, V_DDA, V_OFFSET, V_BIAS, and V_RESET. All V_SS connections are also required.

(2) V_OFFSET supply transients must fall within specified voltages.

(3) Exceeding the recommended allowable absolute voltage difference between V_DDA and V_DD may result in excessive current draw.

(4) Exceeding the recommended allowable absolute voltage difference between V_BIAS and V_OFFSET may result in excessive current draw.

(5) Exceeding the recommended allowable absolute voltage difference between V_BIAS and V_RESET may result in excessive current draw.

(6) This maximum input voltage rating applies when each input of a differential pair is at the same voltage potential. LVDS differential inputs must not exceed the specified limit or damage may result to the internal termination resistors.

(7) Differential inputs must not exceed the specified limit or damage may result to the internal termination resistors. Specification applies to both the high speed serial interface (HSSI) and the low speed interface (LSI).

(8) The array temperature cannot be measured directly and must be computed analytically from the temperature measured at the test point (TP1) shown in Figure 6-1 and the package thermal resistances using the calculation in Section 6.6.

(9) Refer to Section 6.6 for the calculation.
