1. Differential output buffers are internally loaded by 75
2. See “Definition of Terms” on page 48.
3. Histogram testing based on sampling of a 10 MHz sinewave at 50 MSPS.
4. Output error amplitude < ± 4 lsb around correct code (including gain and offset error).
5. Maximum jitter value obtained for single-ended clock input on the JTS8388B die (chip on board): 200 fs. (500 fs expected on
6. Digital output back termination options depicted in Application Notes.
7. With a typical value of TD = 465 ps, at 1 GSPS, the timing safety margin for the data storing using the ECLinPS 10E452 out-
8. The clock inputs may be indifferently entered in differential or single-ended, using ECL levels or 4 dBm typical power level
9. At 1 GSPS, 50/50 clock duty cycle, TC2 = 500 ps (TC1). TDR - TOD = -100 ps (typ) does not depend on the sampling rate.
10. Specified loading conditions for digital outputs:
11. Termination load parasitic capacitance derating values:
12. Apply proper 50/75 impedance traces propagation time derating values: 6 ps/mm (155 ps/inch) for TSEV8388B Evaluation
13. Values for TOD and TDR track each other over temperature, (1% variation for TOD-TDR per 100 C temperature variation).
14. Min value guarantees performance. Max value guarantees functionality.
15. Min value guarantees functionality. Max value guarantees performance.

Therefore TOD-TDR variation over temperature is negligible. Moreover, the internal (on-chip) and package skews between
each Data TODs and TDR effect can be considered as negligible. Consequently, minimum values for TOD and TDR are
never more than 100 ps apart. The same is true for the TOD and TDR maximum values (see Advanced Application Notes
about “TOD-TDR Variation Over Temperature” on page 27).
