AC Characteristics
TCASE = -40 °C to +95 °C, appropriate heat sinking may be required, for package parts. Device is AC-tested in the temperature
range 0 °C to 85 °C, specifications from -40 °C to +95 °C are guaranteed by design.
TDIE BACK = -30 °C to +100 °C, appropriate heat sinking may be required, for dies. Die is not AC-tested. Specifications are
guaranteed by design.

Note 1: RLOAD = 25 W to VCC connected to pin IM. ILD = 50 mA. Rise/Fall times at 20 – 80 % of HI/LO voltage levels. IMB con-
nected to VCC.
Note 2: Added jitter. Measured as a peak-peak jitter value on a sampling oscilloscope in 60 s period. Measured with the data re-
timing enabled, and using the retiming clock signal as trigger for the oscilloscope.
Note 3: Load is equivalent circuit of LD module, see Figure 10 on page 5 . Input signal is PN23 (223 -1 PRBS). Measured on the
optical output of LD module. These specs are target specs.
