Notes:
1. Measured at the end of the fiber optic cable with large area detector.
2. Pulsed LED operation at I
> 80 mA will cause increased link t
PLH
propagation delay time. This extended t
PLH
time contributes to
increased pulse width distortion of the receiver output signal.
3. The LED drive circuit of Figure 11 is required for 1 MBd operation of the HFBR-25X2/25X4.

Notes:
1. 1.6 mm below seating plane.
2. It is essential that a bypass capacitor 0.01
μ
F be connected from pin 2 to pin 3 of the receiver. Total lead length between both ends
of the capacitor and the pins should not exceed 20 mm.
