Electrical Clock Recovery Modules
80A05/80A07 Modules for DSA8200 Series Oscilloscopes
|
Features & Benefits
- Electrical Clock Recovery for:
- Enumerated Bit Rates between 50 Mb/s and 12.6 Gb/s
- Continuously Variable Rates from 100 Mb/s to 12.5 Gb/s Enables
Support for Current, Emerging, and Future Bit Rate Needs
- High Jitter Tolerance, Slow Slew Rate Tolerance for Recovering
Clocks from Stressed, Degraded, or Spread-spectrum Clocked Signals
- Excellent Time Base Stability and Ultra-low Residual Jitter
(as low as 250 fsRMS) for Best Measurement System Fidelity
- Unequaled PLL Bandwidth and Roll-off Shape Control (Tunable
loop bandwidth of 100 kHz to 12 MHz) Enables Control Required by Many
Compliance Standard Tests
- Clean 50 Ω Path for the Best Signal
Acquisition Fidelity
Applications
- High-speed Serial Data Link
and Device Characterization for Computer, Communications, and Consumer
Applications
- Compliance Testing of Electrical Signaling
- High-speed Optical Communications Testing
- Jitter, Noise,
BER, and Signal Impairment Analysis
- Testing of Frequency
Agile or Multirate Devices
The 80A05 and 80A07 Electrical Clock Recovery Modules enable clock
recovery for electrical signals. Additionally, the 80A05 provides
internal routing of the recovered clock for triggering of the 8200*1 Series oscilloscopes.
The 80A05 recovers clocks
from serial data streams for all of the most common electrical standards
in the 50 Mb/s to 3.188 Gb/s range (continuous coverage) plus the
(fixed) rate of 4.25 Gb/s. Option 10G adds support for user-selectable
rates in the following ranges:
- 3.267 to 4.250 Gb/s;
- 4.900 to 6.375 Gb/s; and
- 9.800 to 12.60 Gb/s range
The 80A05 provides high level of integration and the best
sensitivity available, and is the optimal solution for testing of
optical transmitter components and electrical components of optical
systems. The 80A05 PLL loop bandwidth selection is automatic with
no interaction, leading to easy setup and operation.
The 80A07
recovers clocks from serial data streams for all of the most common
electrical standards in the continuous 100 Mb/s to 12.5 Gb/s range.
Auto-locking capability is selectable from the user interface or programmatic
interface, so the design and test engineers can search and lock onto
signals of unknown data rates. The 80A07 offers complete configurability
and state-of-the-art specifications and is the preferred solution
for most serial data standards due to excellent stability, superior
Jitter and slew rate tolerance for recovering clocks from stressed
or degraded signals, and unequaled PLL bandwidth and roll-off shape
control for either Golden PLL compliance testing or custom PLL response.
The 80A07 also locks on spread-spectrum signals.
In addition
to standard rate support, users can specify custom bit rates on either
of the two modules in order to test devices, modules, and systems
running at emerging or nonstandard rates. The wide clock recovery
ranges support for user-specified bit rates provide complete clock
recovery solutions for testing a wide range of computer, communications,
and consumer electronics signaling rates and standards.
The
80C12 optical module with either the 80A05 or 80A07 clock recovery
modules provides a complete solution for optical rates between 155 Mb/s
and 12.6 Gb/s.
*1 Also compatible with CSA/TDS8200,
CSA/TDS8000B, and CSA/TDS8000 sampling oscilloscopes.
Both
modules accept either single-ended or differential signals at their
inputs. With either single-ended or differential signals, the attenuated
but otherwise unmodified input signal is available on output connectors
on the front panel of the modules. The signal path to these front-panel
outputs has been carefully designed to preserve signal fidelity well
beyond the frequency corresponding to the maximum bit rate addressed
by the clock recovery circuit. The front-panel output signals can
therefore be connected to a high-frequency sampling module (such as
80E07) and be acquired for analysis while preserving high-frequency
features of the signal.
Tektronix clock recovery solutions
combine simplicity of use with excellent flexibility; the full rate
recovered clock or its sub-rate is available on the modules’ front
panel to clock or trigger other equipment.

work to 20 GHz.
Interconnect Cables (3rd party)
Tektronix recommends using quality high-performance interconnect
cables with Tektronix high-bandwidth products in order to minimize
measurement degradation and variations. The W.L. Gore & Associates'
cable assemblies are compatible with the 2.92 mm, 2.4 mm, and 1.85 mm
connector interface. Assemblies can be ordered by contacting Gore
by phone at (800) 356-4622, or on the web at www.gore.com/tektronix.
Firmware Support
The 80A07 is a standalone clock
recovery module and as such has its own front-panel controls. In addition,
it ships with a virtual front-panel control application which can
be installed on 8200*1 Series sampling oscilloscopes running
version 2.0 or later or on a Windows PC running Windows 2000 or Windows
XP. The controlling processor (8200*1 Series oscilloscope
or Windows PC) must be connected to the 80A07 by a USB cable in order
for this virtual front-panel control application to work.
When
running on an 8200*1 Series sampling oscilloscope or Windows
PC, the virtual front-panel control application can be started from
the Windows desktop or start menu. Additionally, if the 8200*1 Series sampling oscilloscope is running firmware version
2.4 or later, this control application can be invoked using the Apps menu within the sampling oscilloscope application.
Remote control of the 80A07 is available with a software development
kit which comes standard with the 80A07.
