Low-Jitter, Low-Noise LVPECL-to-LVDS Level

Translator in an SC70 Package

_______________________________________________________________________________________

Note 1: All devices are 100% tested at TA = +25°C. Limits over temperature are guaranteed by design and characterization.

Note 2: Current into a pin is defined as positive. Current out of a pin is defined as negative. All voltages are referenced to ground

except VTH, VTL, VOD, and ∆VOD.

Note 3: Guaranteed by design and characterization.

Note 4: Signal generator output (unless otherwise noted): frequency = 200MHz, 50% duty cycle, RO = 50Ω, tR = 1.5ns, and tF =

1.5ns (0% to 100%).

Note 5: CL includes scope probe and test jig capacitance.

Note 6: Signal generator output for tDJ: VOD = 150mV, VOS = 1.2V, tDJ includes pulse (duty cycle) skew.

Note 7: Signal generator output for tRJ: VOD = 150mV, VOS = 1.2V.

Note 8: tSKPP1 is the magnitude difference of any differential propagation delays between devices operating over rated conditions

at the same supply voltage, input common-mode voltage, and ambient temperature.

Note 9: tSKPP2 is the magnitude difference of any differential propagation delays between devices operating over rated conditions.

Note 10: Device meets VOD DC specifications and AC specifications while operating at fMAX.

Note 11: Jitter added to the input signal.

AC ELECTRICAL CHARACTERISTICS

(VCC = 3.0V to 3.6V, RL = 100Ω ±1%, CL = 10pF,

|VID| = 0.15V to VCC, VCM = |VID / 2| to VCC - |VID / 2|, TA = -40°C to +85°C, unless

otherwise noted. Typical values are at VCC = 3.3V, TA = +25°C.) (Notes 3, 4, 5) (Figures 3, 4)
