Notes:
1. 2.0 mm from where leads enter case.
2. The signal output is referred to VCC, and does not reject noise from the VCC power supply. Consequently, the VCC power supply must be filtered.
The recommended power supply is +5 V on VCC for typical usage with +5 V ECL logic. A -5 V power supply on VEE is used for test purposes to
minimize power supply noise.
3. Typical specifications are for operation at TA = 25° C and VCC = +5 VDC.
4. The test circuit layout should be in accordance with good high frequency circuit design techniques.
5. Measured with a 9-pole “brick wall” low-pass filter [Mini-CircuitsTM, BLP-100*] with -3 dB bandwidth of 100 MHz.
6. -11.0 dBm is the maximum peak input optical power 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 specifled 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-1312T) will be approximately 0.6 ns longer than the specifled rise and fall times.
E.g.: measured tr,f [(specifled tr,f)2 + (test source optical tr,f)2]1/2.
9. 10 ns pulse width, 50% duty cycle, at the 50% amplitude point of the waveform.
10. Percent overshoot is defined as: ((VPK - V100%)/V100%) x 100% . The overshoot is typically 2% with an input optical rise time ≤1.5 ns.
11. The bandwidth*risetime product is typically 0.41 because the HFBR-2316TZ has a second-order bandwidth limiting characteristic.
