Electrical Characteristics - DIF 0.7V Current Mode Differential Pair
T
Notes:
1.Guaranteed by design and characterization, not 100% tested in production.
2. All Long Term Accuracy and Clock Period specifications are guaranteed assuming that the input frequency meets CK410 accuracy requirements
3.IREF = VDD/(3xRR). For RR = 475Ω (1%), IREF = 2.32mA. IOH = 6 x IREF and VOH = 0.7V @ ZO=50Ω.
4. Measured into fixed 2 pF load cap. Input to output skew is measured at the first output edge following the corresponding input.
5. Measured from differential cross-point to differential cross-point
6. All Bypass Mode Input-to-Output specs refer to the timing between an input edge and the specific output edge created by it.
7. This device does not introduce any ppm errors to the input clock.
