Notes:

1. 1.6 mm below seating plane.

2. The signal output is an emitter follower, which does not reject noise in the power supply. The power supply must be filtered as in

Figure 9.

3. Typical data are at 25

°C and V

4. Pin 1 should be ac coupled to a load

≥ 510 Ω with load capacitance less than 5 pF.

5. Measured with a 3 pole Bessel filter with a 75 MHz, -3 dB bandwidth. No modulation appled to Tx.

6. The maximum Peak Input Optical Power is the level at which the Pulse Width Distortion is guaranteed to be less than the PWD listed

designing links up to 125 MBd (for both POF and HCS input conditions).

7. 10 ns pulse width, 50% duty cycle, at the 50% amplitude point of the waveform.

8. Percent overshoot is defined at:

––––––––––––

× 100%

9. Pins 9 and 10 are primarily for mounting and retaining purposes, but are electrically connected with the conductive housing. Pins 5

and 6 are electrically unconnected. It is recommended that pins 5 and 6 be connected to Rx ground to reduce coupling of electrical

noise. Refer to Figure 1. The connections between pins 1 and 2 of the HFBR-5527 and pins 13 and 12 of the MC10H116 should be

adjacent and nearly the same length to maximize the common mode rejection of the MC10H116 to eliminate cross talk between the

transmitter and receiver.

10. If there is no input optical power to the receiver (no transmitted signal) electrical noise can result in false triggering of the receiver.

In typical applications, data encoding and error detection prevent random triggering from being interpreted as valid data.
