The DFE-Q devices are supplied by the first AFE at pin CL15 with the synchronized
15.36 MHz clock. The IOM
programmed by the two slot pins. Starting from channel no. 0/4/8/12 always four
subsequent channels are occupied.
Alternatively the clocking scheme as shown in
devices are to be clocked (e.g. in a 16-channel line card application). Instead to supply
the 2nd AFE with the master clock at pin CL15, here the 15.36 MHz master clock is input
at pin XIN. Thereby pin CL15 is configured as output and passes the 15.36 MHz clock
on to the attached DFE-Q. If the clock chain is extended in the same way by another two
AFE/DFE-Q chip sets a 16-channel line card application can be realized with just one
single crystal. Note that the 15.36 MHz clock is inverted once by the AFE if it is input at
XIN and output at CL15. This way the duty cycle is recovered again.
