6.5 Configuring the XRT8001 WAN Clock into the
“E1 to T1 – Forward/Master” Mode
The user can configure the XRT8001 WAN Clock to
operate in the “E1 to T1 – Forward/Master” Mode by
executing the following steps:
Step 1
– Configure the XRT8001 to operate in the
“MASTER” Mode, by pulling the “MSB” input pin (pin 8)
to VDD.
Step 2
– Write the binary value “1000” into Command
Register CR0, as illustrated below
:
Command Register CR0 (Address = 0x00)

Q x 2.048MHz
Where: 1 < Q < 16
1.544MHz
1.544MHz
This step configures the XRT8001 WAN Clock to
operate in the “E1 to T1 – Forward/Master” Mode.
Note:
If the user wishes to output a clock signal via the
CLK1 output signal, then he/she should also write a “1”
into the “PL1EN” bit-field within Command Register,
CR0.
Step 3
– Next, you need to specify the value for “Q”
*(e.g., as in the “Q x 2.048MHz” clock signal which
will be applied to the “FIN” input pin).
The user accomplishes this writing the binary
expression for “Q - 1” into Command Register, CR1,
as illustrated below.
