Plastic and Hard Clad Silica Optical Fiber Receiver Application Circuit:
Performance
25 C unless otherwise stated.
Notes:
4. Performance in response to a signal from the HFBR-15X7 transmitter driven with the recommended circuit at 1-125 MBd over 1 meter
5. Terminated through a 50
6. If there is no input optical power to the receiver, electrical noise can result in false triggering of the receiver. In typical applications,
