PRODUCTION DATA.
Figure 25 shows a typical implementation for the HCSL output driver mode. HCSL requires external 50-Ω termination resistors. Optionally, source resistors in the range from 22 Ω to 33 Ω are employed to eliminate ringing.
For HSCL outputs, set OUTCHxx_DRIV_MODE to 0x3F.
Figure 26 and Figure 27 show different connection methods to a LVPECL receiver.
