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.
