ADSP-BF542/ADSP-BF544/ADSP-BF547/ADSP-BF548/ADSP-BF549
Fiber optic transceiver (FOT) connections:
Keep the traces between the ADSP-BF549 processor and
the FOT as short as possible.
The receive data trace connecting the FOT receive data
output pin to the ADSP-BF549 PH6/MRX input pin should
have a 0
series termination resistor placed close to the
FOT receive data output pin. Typically, the edge rate of the
FOT receive data signal driven by the FOT is very slow, and
further degradation of the edge rate is not desirable.
The transmit data trace connecting the ADSP-BF549
PH5/MTX output pin to the FOT transmit data input pin
should have a 27
series termination resistor placed close
to the ADSP-BF549 PH5/MTX pin.
The receive data trace and the transmit data trace between
the ADSP-BF549 processor and the FOT should not be
routed close to each other in parallel over long distances to
avoid crosstalk.
