AFBR-1624Z/1629Z Transmitter The AFBR-1624Z/1629Z transmitter incorporates a 650 nm LED and integrated driver IC in a light gray, nonconductive plastic Versatile Link housing. Its input data is compatible with TTL logic level. This transmitter can operate from DC to 50 MBd with any kind of data pattern using 1 mm plastic optical fi ber (POF). Within the specifi ed ranges AFBR-1624Z and AFBR-1629Z devices will support a BER < 10E-9.

Measured after 1meter 0.5 NA 1mm POF with polished connector end face. 4. Pulse width is measured at 50% threshold using a rising edge trigger tested with PRBS-7 pattern 5. Electrical input pulse width is determined at 1.5 V and dU/dt between 1 V and 2 V shall not be less than 1 V/ns. 6. The fi rst pulse is shorter as the LED is completely discharged. This helps to mitigate the increase of pulse width of the fi rst pulse of the Receiver

AV02-3407EN - May 7, 2012 AFBR-2624Z/2529Z Receiver The AFBR-2624Z/2529Z receiver consists of a digitalizing IC with integrated photodiode to produce an output level that is compatible with TTL logic. The integrated photodiode and the following amplifi er uses a fully diff erential approach with an active and a passive area for an improved EMI performance. Within the specifi ed ranges AFBR-2529Z and AFBR- 2624Z devices will support a BER <10E-9.

Standard TTL output. 2. Measured with R L = 50 k and CL = 15 pF 3. Optical Power generated by a standard Avago Technologies Transmitter, with ideal alignment to the photodiode using a 1 mm PO F (NA = 0.5). 6. Optical input of 50 MBaud PRBS-7 pattern and 50% duty cycle. 7. Pulse width is measured at 50% threshold using a rising edge trigger and PRBS-7 pattern. 8. If data rate is below 1Mbaud the pulse width distortion would be equal to the pulse width distortion of the 1st to 3rd puls es for higher datarates. 9. The threshold of the 1st pulse of a data sequence is diffi cult to adjust and therefore the pulse width distortion up to the 3rd pulse is higher than for all other pulses (worst case for the 1st pulse). This strongly depends on the quality of the rising and falling edge of the optical input. The faster the edges the smaller the pulse width variation. Furthermore lower data rates would result in the same issue as all the pulse become 1st pulses. 10. Output low for AFBR-2624Z and Output high for AFBR-2529Z.
