The following section provides the layout guidelines to ensure good thermal performance and power supply connections for the CDCDB803.

In Section 11.2, the CDCDB803 has 85-Ω differential output impedance LP-HCSL format drivers as per register default settings. All transmission lines connected to CKx pins should be 85-Ω differential impedance, 42.5-Ω single-ended impedance to avoid reflections and increased radiated emissions. If 100-Ω output impedance is enabled, the transmission lines connected to CKx pins should be 100-Ω differential impedance, 50-Ω single-ended impedance. Take care to eliminate or reduce stubs on the transmission lines.
