APPENDIX A
Layout and General Suggestions

Establish controlled impedance stripline, microstrip, or co-planar construction techniques.
Signal paths should have, approximately, the same width as the device pads.
All differential paths are critical timing paths, where skew should be matched to within
±
10ps.
Signal trace impedance should not vary more than
±
5%. If in doubt, perform TDR analysis of all high-speed signal
traces.
Maintain compact filter networks as close to filter pins as possible. Provide ground plane relief under filter path to
reduce stray capacitance. Be careful of crosstalk coupling into the filter network.
Maintain low jitter on the REFCLK input. Isolate the XTAL oscillator from power supply noise by adequately
decoupling. Keep XTAL oscillator close to device, and minimize capacitive coupling from adjacent signals.
Higher speed operation may require use of fundamental-tone (third-overtone typically have more jitter) crystal based
oscillator for optimum performance. Evaluate and compare candidates by measuring TXCLK jitter.
All unused outputs must be terminated. To conserve power, unused PECL outputs can be terminated with a 1k
resistor to V
