ELECTRICAL CHARACTERISTICS (continued)
(V
CC
= +2.97V to +3.63V and T
A
= -40°C to +85°C. Typical values are at V
CC
= +3.3V, source capacitance (C
IN
) = 0.85pF, and T
A
=
+25°C, unless otherwise noted.) (Notes 1, 2)
Note 1:
Dice are designed to operate with junction temperatures of -40

C to +110
°
C but are tested and guaranteed only at T
A
= 25°C.
Note 2:
Source capacitance represents the total capacitance at the IN pad during characterization of the noise and bandwidth para-
meters.
Note 3:
Guaranteed by design and characterization.
Note 4:
Input-referred noise is:
Note 5:
Deterministic jitter is the sum of pulse-width distortion (PWD) and pattern-dependent jitter (PDJ).
Note 6:
Power-supply noise rejection PSNR = -20log(

/
V

V
OUT
is the differential output voltage and
V
