Notes:
1. 2.0 mm from where leads enter case.
2. The signal output is an emitter
follower, which does not reject noise
from V
CC
. Consequently, the power
supply must be filtered. The recom-
mended supply is +5 V on V
CC
for
typical usage with +5 V ECL logic. A
-5 V supply on V
EE
is used for test
purposes to minimize supply noise.
3. Typical specifications are for
operation at T

4. The test circuit layout should be in
accordance with good high frequency
circuit design techniques.
5. Measured with a Mini-Circuits 9-pole
“brick wall” low-pass filter, BLP-100,
with -3 dB bandwidth of 100 MHz.
6. -14 dBm is the maximum peak input
optical power from single-mode fiber
for which pulse-width distortion is
less than 1 ns.
7. Electrical bandwidth is the frequency
where the responsivity is -3 dB
(electrical) below the responsivity
measured at 50 MHz.
8. The bandwidth * risetime product is
typically 0.41 because the HFBR-
2315T/2315M has a second-order
bandwidth limiting characteristic.
9. The specified rise and fall times are
referenced to a fast square wave
optical source. Rise and fall times
measured using an LED optical
source with a 2.0 ns rise and fall time
(such as the HFBR-1315TM/1315M)
will be approximately 0.6 ns longer
than the specified rise and fall times.

the 50% amplitude point of the
waveform.
11. Percent overshoot is defined as:
((V
PK
- V
100%
)/V
100%
) x 100%. The
overshoot is typically 2% with an
input optical rise time < 1.5 ns.
