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
of HFBR-R/EXXYYY plastic optical fiber or 1 meter of HFBR-H/VXXYYY hard clad silica optical fiber.
5. Terminated through a 50 Ω resistor to VCC - 2 V.
6. If there is no input optical power to the receiver, 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. Refer to Applications Note 1066 for
design guidelines.
