(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.

(1) Typical parameters measured at V_CC = 3.3 V, T_A = 25°C, and represent most likely parametric norms at the time of product characterization. The typical specifications are not ensured.

(2) IN+ and IN− are generic names refer to one of the many pairs of complimentary inputs of the DS25MB100. OUT+ and OUT− are generic names refer to one of the many pairs of the complimentary outputs of the DS25MB100. Differential input voltage V_ID is defined as |IN+–IN−|. Differential output voltage V_OD is defined as |OUT+–OUT−|.

(3) K28.7 pattern is a 10-bit repeating pattern of K28.7 code group {001111 1000}K28.5 pattern is a 20-bit repeating pattern of +K28.5 and −K28.5 code groups {110000 0101 001111 1010}

(4) Device output random jitter is a measurement of the random jitter contribution from the device. It is derived by the equation sqrt(RJ_OUT²– RJ_IN²), where RJ_OUT is the total random jitter measured at the output of the device in ps_rms, RJ_IN is the random jitter of the pattern generator driving the device.

(5) Device output deterministic jitter is a measurement of the deterministic jitter contribution from the device. It is derived by the equation (DJ_OUT–DJ_IN), where DJ_OUT is the total peak-to-peak deterministic jitter measured at the output of the device in ps_p-p, DJ_IN is the peak-to-peak deterministic jitter of the pattern generator driving the device.

(6) This parameter is ensured by design and/or characterization. It is not tested in production.

(1) t_SKO is the magnitude difference in the propagation delays among data paths. An example is the output skew among data paths from IN0± to OUT± and IN1± to OUT±. Another example is the output skew among data paths from IN± to OUT0± and IN± to OUT1±. t_SKOalso refers to the delay skew of the loopback paths of the same port and between similar data paths. An example is the output skew among data paths IN0± to OUT0± and IN1± to OUT1±.
