Printed on recycled paper. ©2004, Pulse Engineering, Inc. Application Notes: 1. Values for R1 and R2 are determined by system transmit amplitude requirements. A value of 0 Ω for R1 and R2 will yield an output with maximum amplitude but distorted due to impedance mismatch. A value of 68 Ω will provide an optimum waveform but have 6.0 dB insertion loss. If 6.0dB loss is too great, select at least 15 Ω to obtain a reasonable compromise between insertion loss and waveshape. The typical value for C1, C2, C3, and C4 is 0.1µF. 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.
