RJ Device random jitter, rms BERT setting 10–15 0.8 2 ps-rms Alternating 10-pattern. (1) All typical values are at 25°C and with 3.3-V supply unless otherwise noted. (2) tsk(p) is the magnitude of the time difference between the tPLH and tPHL of any output of a single device. (3) tsk(o) is the magnitude of the time difference between the tPLH and tPHL of any two outputs of a single device. (4) tsk(pp) is the magnitude of the difference in propagation delay times between any specified terminals of two devices when both devices operate with the same supply voltages, at the same temperature, and have identical packages and test circuits. 6 Submit Documentation Feedback Copyright © 2009, Texas Instruments Incorporated Product Folder Link(s): SN65LVCP202 |
