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 non-standard 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.
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.
