Application Notes:
1. Values for R1 and R2 are determined by system transmit
amplitude requirements. A value of 0
for R1 and R2 will
yield an output with maximum amplitude but distorted due to
impedance mismatch. A value of 68
will provide an
optimum waveform but have 6.0 dB insertion loss. If 6.0 dB
loss is too great, select at least 15
to obtain a reasonable
compromise between insertion loss and waveshape. The
typical value for C1, C2, C3, and C4 is 0.1 μF.
2. To maintain return loss and signal integrity, transmission line
methods must be used when designing the PCB. For best
performance the common mode choke should be located no
more than 1" from the cable connector.
3. One example of a possible layout is shown below for a Fibre
Channel application. Note that actual board layouts will vary
based upon specific applications and EMC considerations.
