1Gbps to 11.3Gbps, SFP+ Laser Driver
with Laser Impedance Mismatch Tolerance
ELECTRICAL CHARACTERISTICS (continued)
(V CC = +2.85V to +3.63V, T A = -40°C to +85°C, and Figure 1. Guaranteed by design and characterization from T A = -40°C to +95°C.
Typical values are at V CC = +3.3V, I BIAS = 60mA, I MOD = 40mA, 25 I differential output load, and T A = +25°C, unless otherwise
noted.) (Note 2)

Note 2: Guaranteed by design and characterization (T A = -40 N C to +95 N C).
Note 3: BIAS is connected to 2.0V. TOUT+/TOUT- are connected through pullup inductors to a separate supply that is equal to V CCT .
Note 4: Stability is defined as [(I_measured) - (I_reference)]/(I_reference) over the listed current range, temperature, and V CC =
V CCREF Q 5%. V CCREF = 3.0V to 3.45V. Reference current measured at V CCREF , T A = +25 N C.
Note 5: Measured with K28.5 data pattern at 10.7Gbps and with a (2 7 - 1 PRBS + 72 zeros + 2 7 - 1 PRBS (inverted) + 72 ones)
pattern at 11.3Gbps.
