Notes:
1. Typical specications are for operation at T
A
= 25°C and V
CC
= +5 V
DC
.
2. The test circuit layout should be in accordance with good high frequency circuit design techniques.
3. Measured with a 9-pole “brick wall” low-pass lter [Mini-Circuits
TM
, BLP-100*] with -3 dB bandwidth of 100 MHz.
4. -11.0 dBm is the maximum peak input optical power for which pulse-width distortion is less than 1 ns.
5. Electrical bandwidth is the frequency where the responsivity is -3 dB (electrical) below the responsivity measured at 50 MHz.
6. The specied 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-1312TZ) will be approximately 0.6 ns longer than the specied rise and fall times.

7. 10 ns pulse width, 50% duty cycle, at the 50% amplitude point of the waveform.
8. Percent overshoot is dened as: ((V
PK
- V
100%
)/V
100%
) x 100% . The overshoot is typically 2% with an input optical rise time ≤1.5 ns.
9. The bandwidth*risetime product is typically 0.41 because the HFBR-2316TZ has a second-order bandwidth limiting characteristic.
10. The signal output is referred to V
CC
, and does not reject noise from the V
CC
power supply. Consequently, the V
CC
power supply must be ltered.
The recommended power supply is +5 V on V
CC
for typical usage with +5 V ECL logic. A -5 V power supply on V
EE
is used for test purposes to
minimize power supply noise.
