XRT8001
2.2 The Reverse/Master Mode
In the Reverse/Master Mode, the XRT8001 will accept
either a 56kHz or a 64kHz clock signal via the FIN input
pin, and will generate either a 1.544MHz or a 2.048MHz
clock signal via the Clock Output signals.
Figure 8, presents a simple illustration of the XRT8001
WAN Clock operating in the “Reverse/Master Mode.”
