Getting Started
The Tektronix 80A05 Electrical Clock Recovery Module will recover the clock
from electrical data for all Tektronix electrical modules. The 80A05 Electrical
Clock Recovery Module provides a solution for triggering the mainframe from
single-ended or differential electrical signals. The 80A05 can also be used as a
general purpose clock recovery solution.
NOTE. Proper operation of the 80A05 module requires that the operating system
software installed on the main instrument is version 2.0 or greater. To display
the version installed, select About TDS/CSA8000 fromtheHelpmenuinthe
user interface.

Installation
The 80A05 module fits into one of the large module compartments on the front
panel of an 8000 Series instrument. See Figure 1.
To install a module, first power off the instrument using the front-panel
On/Standby switch. Then place the module in a compartment, and slowly push it
in with firm pressure. Once the module is seated, turn the hold-down screws on
the module to tighten the module into place. See Figure 1. When a 80A05
module is installed into one of the large slots, one of the smaller slots will be
disabled. Refer to the instrument’s online help to identify the disabled slot.
CAUTION. To prevent damage to the module or instrument, never install or
remove a module when the instrument is powered on or when either input
connector is unprotected.

80A05 Electrical Clock Recovery Module User Manual 5
To prevent electrostatic damage to the 8000 Series instrument and modules,
follow the precautions described in this manual and the manuals that come with
your instrument.
Circuitry in the module is very susceptible to damage from electrostatic
discharge or from overdrive signals. Be sure to only operate the module in a
static-controlled environment. Be sure to discharge to ground any electrostatic
charge that may be present on the center and outer connectors of cables before
attaching the cable to the module.
Know your signal source. If it is capable of delivering overvoltages, it is safer to
not depend on the signal source settings for protection, but instead use an
external attenuator that protects the input from the worst-case conditions. For
example, for a 10 V maximum source connected to a 1 V maximum module, use
a 10X attenuator. Where possible, connect your cables to the signal source first,
and to the module second.
CAUTION. To prevent damage from electrostatic discharge, install the attached
50 Ωterminations on the I/O connectors before removing the module from an
instrument, storing, or when not in use. Store the module in a static-free
container, such as the shipping container. Whenever you move the module from
one instrument to another, use a static-free container to transport the module.
To prevent damage to the module, discharge to ground any electrostatic charge
that may be present on the center and outer conductors of cables before
attaching the cables to the module.
To prevent damage to the module, do not create an ESD antenna by leaving
cables dangling off the module input with the other end open.
To prevent damage to the module or instrument, never install or remove a
module when the instrument is powered on.
Always use a wrist strap (provided with your instrument) when handling
modules or making signal connections. Wear antistatic clothing and work in a
static-free workstation when using modules.
To prevent damage to the module or instrument, do not apply a signal outside
the Maximum Input Voltage Swing for your module.
For information on creating a static-controlled workstation, consult the Electron-
ic Industries Association document, EIA-625; Requirements for Handling
Electrostatic-Discharge-Sensitive (ESDS) Devices.

Operating Basics
This chapter familiarizes you with the operation of your module. This chapter
describes the front-panel controls and connectors, interaction of the module with
your instrument, user adjustments, and the programmer interface.
Usage
Figures 2 and 3 on page 8, show the front panel of the module and identifies the
connectors and indicators.
CAUTION. To prevent damage to your module or instrument, do not apply a
signal outside the Maximum Input Voltage Swing for your module.
To prevent electrostatic damage to the instrument and modules, follow the
precautions described in this manual and the manuals accompanying your
instrument. (See Electrostatic Discharge starting on page 5.)
Always use a wrist strap (provided with your instrument) when handling
modules or making signal connections.
The input circuitry in your module is very susceptible to damage from overdrive
signals and electrostatic discharge. Never apply a DC or peak voltage greater
than the Maximum Operating Range (see Table 4 on page 11) of your module.
Only operate the instrument and module in a static-controlled environment.
Front Panel
The 80A05 module contains three primary features:
Use these to secure the module in the instrument module compartment once
connected. Turn clockwise to secure and counterclockwise to release. To prevent
damage to the module, use the compartment ejectors to remove the module from
the compartment (see Figure 1 on page 4 for the location of the ejectors).
There is one LED on the front panel of the 80A05 module that indicates the
clock recovery circuitry is on and programmed to the requested bit rate. The
80A05 module receives power through the TEKPROBE-Sampling interface.
When the module is receiving power the LED is lighted. If the module is
installed but is not receiving power, check that the module is seated correctly.

Additionally, turn the hold-down screws clockwise to make sure the module is
installed tightly.
Figure 2: 80A05 module front panel
Figure 3: 80A05- 10G module front panel
The connectors on the front panel of the 80A05 module provide connections for
the input and output signals. All connectors are SMA female connectors.
Connector Care. Never attach a cable to a sampling-module connector if the cable
has a worn or damaged connector because you may damage the sampling-mod-
ule connector. Use extra care when attaching or removing a cable from the
connectors. Turn only the nut, not the cable. When attaching a cable to a
sampling-module connector, align the connectors carefully before turning the
nut. Use light finger pressure to make this initial connection. Then tighten the
nut lightly with a wrench.
NOTE. For best repeatability and to prolong connector life, use a torque wrench,
and tighten the connection to the range of 79-112 N⋅cm (7-10 in lb).
If the module connectors will receive heavy use, such as in a production
environment, you should install adapters (such as a Tektronix part number
015-0549-xx for 3.5 mm connectors) on the module to make connections to the
device under test.
