XRT8001
2.6 The “Forward/Slave” Mode
In the “Forward/Slave” Mode, the XRT8001 will
accept an 8kHz clock signal via the Reference
Clock Input (FIN), and will output a “L x 64kHz or L
x 56kHz” clock signal (where L can range from 1 to
32) via the CLK1 and CLK2 output pins.
Figure 12 presents a simple illustration of the
XRT8001 WAN Clock operating in the “Forward/
Slave” Mode.
