- connected U9.pin31 BYTE# to VCCO_1 (3V3)
- Terminate the end of the CCLK transmission line with a parallel termination of 100Ω/R164/1%/0402 to VCCO and 100Ω/R165/1%/0402 to GND (the Thevenin equivalent of VCCO/2, and assuming a trace characteristic impedance of 50Ω).
- Route the CCLK net as a 50Ω controlled impedance transmission line.
- Stubs, if necessary, must be shorter than 8 mm (0.3 inches).
