Notes:
1. Differential output buffers are internally loaded by 75
resistors. Buffer bias current = 11 mA
2. See “Definition of Terms” on page 46
3. Histogram testing based on sampling of a 10 MHz sinewave at 50 Msps
4. Output error amplitude < ±4 lsb around worst code
5. Maximum jitter value obtained for single-ended clock input on the die (chip on board): 200 fs
6. Digital output back termination options depicted in Application Notes
7. At 500 Msps, 50/50 clock duty cycle, TC2 = 2 ns (TC1). TDR - TOD = -100 ps (typ) does not depend on the sampling rate
8. Specified loading conditions for digital outputs:
- 50
or 75 controlled impedance traces properly 50/75 terminated, or unterminated 75 controlled impedance traces
- Controlled impedance traces far end loaded by 1 standard ECLinPS register from Motorola. (i.e.: 10E452) (Typical input
parasitic capacitance of 1.5 pF including package and ESD protections.)
9. Termination load parasitic capacitance derating values:
- 50
or 75 controlled impedance traces properly 50/75 terminated: 60 ps/pF or 75 ps per additionnal ECLinPS load
