ELECTRICAL CHARACTERISTICS (continued)
Note 1: Dice are tested at room temperature only (T
A
= +25°C).
Note 2: V
CC
= +5.5V, R
BIASMAX
= 887Ω, R
MOD
= 887Ω, R
POWERSET

OUT+
= V
OUT-
= 3.0V. Supply

.
Note 3: Total output current must be reduced at high temperatures with packaged product to maintain maximum junction
temperature of T
j
= +150°C. See the Design Procedure section.
Note 4: All AC parameters are measured with a 25Ω load. I
MOD
is the AC current amplitude at either OUT pin. The AC voltage at
OUT is greater than V
CC
- 2.5V.
Note 5: Pulse-width distortion is measured at the 50% crossing point. Data input is a 155MHz square wave, with t
R
≈ 300ps.
Note 6: AC specifications are guaranteed by design and characterization.
