OM1420

The OM1420 Clock Recovery Module mounts in
a slot on the front panel of the Tektronix OI2125
Optical-to-Electrical Receiver and provides clock
recovery rates at OC-192 (9.953280 GB/s) and
OC-192 FEC (10.66423 GB/s).

Use these instructions to install and remove the
module from the OI2125 O/E Receiver. For other
clock recovery module information, including
specifications and performance verification
procedures, refer to the OI2125 O/E Receiver
Instruction Manual, Tektronix part number
071-1053-XX.

To protect the module inputs, always use a
wrist strap when handling the module and
when making signal connections. Always
replace the module terminators before
transporting the module.

CAUTION. To prevent damage to your module,

do not install or remove the module while
the receiver is powered on. Do not apply a
voltage greater than the Maximum
Nondestructive Input V oltage for the module.

Installing the Clock Recovery Module

1. Power off the receiver.

2. Slowly insert the module into the slot in the
front panel until it meets the connector at the
back of the module slot.

3. Firmly push the module in to seat it in the
connector.

4. Turn the hold-down screw clockwise to lock
the module in place.

5. Attach the SMA interconnect cable from the
attenuated data output of the receiver to the
Data In connector on the module.

NOTE. This step is not necessary when using

the module as a stand-alone instrument or
when installing a slot cover module.

6. Power on the receiver.

7. Press the Select Rate button to choose the
recovery rate of the module. LEDs to the left
of the button indicate the rate selected.

Removing the Clock Recovery Module

1. Power off the receiver.

2. Remove any external cables from the input of
the module. This step is not necessary when
removing a slot cover module.

3. Remove the SMA interconnect cable from the
output of the receiver and the input of the
module, if necessary.

4. Replace the terminators on the module. (See
CAUTION.)

5. Turn the hold-down screw counterclockwise
to unlock the module.

6. Move the latch button to the right to eject the
module.

7. Pull the module out of the receiver and store it
in a safe location.

8. If you are not going to use another clock
recovery module, install the slot cover module
in the receiver to limit stray EMI emissions
and to protect the receiver from ambient RF
noise.
