Figure 54. Single-ended Termination Method for Clock I or Clock Q

Output Termination in

1:1 Ratio

When using the integrated DMUX in 1:1 ratio, the valid port is port A. Port B remains

unused.

Port A functions in LVDS mode and the corresponding outputs (DOAI or DOAQ) have to

be 100Ω differentially terminated as shown in Figure 55 on page 52.

The pins corresponding to Port B (DOBI or DOBQ pins) must be left floating (in high

impedance state).

Figure 55 on page 52 is an example of a 1:1 ratio of the integrated DMUX for channel I

(the same applies to channel Q).
