Note 1 : Differential output buffers are internally loaded by 75
W resistors. Buffer bias current = 11 mA.
Note 2 : See definition of terms
Note 3 : Histogram testing based on sampling of a 10 MHz sinewave at 50 MSPS.
Note 4 : Output error amplitude < +/– 4 LSB around worst code.
Note 5 : Maximum jitter value obtained for single-ended clock input.
Note 6 : Digital outputs back termination options depicted in Advanced Application Notes figures 3,4,5 .
Note 7:The clock inputs may be indifferently entered in differential or single-ended, using ECL levels or 4 dBm typical power level into
the 50
W termination resistor of the inphase clock input. (4 dBm into 50 W clock input correspond to 10 dBm power level for the
clock generator.)
Note 8 :TDR–TOD = – 100 ps (typ) does not depend on the sampling rate.
eg : at 500 Msps and 50/50 clock duty cycle : TC2 = 1000 ps (=TC1) and TDR – TOD =– 100 ps (TC1+TC2 = 1 = clock period)
Note 9 : Specified loading conditions for digital outputs :
– 50 ohms or 75 ohms controlled impedance traces properly 50 / 75 ohms terminated, or unterminated 75 ohms controlled
impedance traces.
– Controlled impedance traces far end loaded by 1 standard ECLinPS register from Motorola.
( e.g. : 10E452 ) ( Typical input parasitic capacitance of 1.5 pF including package and ESD protections. )
