2Electrical and Optical Clock Recovery
Solutions
Keysight clock recovery solutions offer a wide data rate range
and are ideal for many transmitter and receiver test setups forcomputers, datacom, and communication standards. The
Keysight Technologies, Inc. electrical clock recovery solutions
provide clock recovery capabilities for electrical non-return-tozero (NRZ) and pulse amplitude modulation 4-level (PAM4)
signals.
lSupports NRZ and PAM4 signalslIntegrated O/E and clock recovery designlOptical splitter: Integrated or External - user suppliedlUltra-low residual random jitter < 100 fs RM

lJitter spectrum analysis (JSA) capabilitylGolden phase-locked loop (PLL) for compliant operation

The Keysight Technologies, Inc. optical/electrical clock recovery integrates electrical clock recovery with
an amplified optical-to-electrical (O/E) converter, enabling it to work for both electrical and opticalapplications. Optional integrated optical splitters are available, which simplifies setup and improves
ease-of-use.
All models include adjustable loop bandwidth and selectable peaking, and provide high sensitivity andlow intrinsic jitter performance that ensures optimal measurement accuracy. The optional jitter spectrum
analysis (JSA) capability provides insight into the magnitude and distribution of low-frequency jitter,
which is helpful in troubleshooting root cause for excessive jitter.
Recover clocks from closed eyes: The N1076B, N1077B, and N1078A electrical clock recovery includes
integrated variable equalizers on both electrical inputs to enable opening closed eyes.

3PLL and jitter spectrum analysis
Use the Keysight Technologies FlexPLL analysis software (N1010300A Signal Integrity Package) tomake fast, accurate, and repeatable measurements of phase-locked loop (PLL) bandwidth/jittertransfer. The N107x can be configured as a jitter receiver, which can be combined with a precision jittersource, such as the Keysight Technologies M8000 Series of BER test solutions, to create a PLL
stimulus-response test system. PCI Express®-approved PLL bandwidth compliance tests are preconfigured, with automatic report generation.

Figure 1. The N107x clock recovery may be configured as a jitter receiver when characterizing phase-locked loop
(PLL) designs using FlexPLL analysis software.

What Does Clock Recovery Do?
Clock recovery takes an incoming data (or clock) signal, locks onto it using a phase-locked loop (PLL)
circuit, and outputs a recovered clock. The recovered clock can be used as a timing reference foroscilloscopes or BERTs.

4

Figure 2. Clock recovery can be used to extract a timing reference signal from an incoming data signal. The amountof jitter on the recovered clock is determined by the loop bandwidth of the PLL.

Standards typically specify loop order, bandwidth, and peaking, all of which determines how much jitteron the incoming signal will appear on the recovered clock (also known as the jitter transfer function, or
JTF). Users can configure the FlexDCA graphical user interface (GUI) to adjust these parameters andensure standards-compliant clock recovery (often referred to as a “golden PLL”).

Why Use Clock Recovery?
Standards compliance
To comply with standards such as IEEE 802.3 Ethernet, Fibre Channel, or the Optical Interworking
Forum – Common Electrical Interface (OIF-CEI), clock recovery must be used when performing
measurements such as jitter, eye width, and/or eye height.

Clock-less devices
Another reason to use clock recovery is when a clock or trigger signal is not provided by the device
under test (DUT), but a clock is required to trigger an oscilloscope, or the error detector in a BERT.

5

Figure 3. Clock recovery provides a compliant trigger signal for use by an oscilloscope or BERT.

Electrical Clock Recovery
The N1076B provides instrument-grade clock recovery on electrical signals up to 64 GBd. Adjustableloop bandwidth and peaking ensures standards-compliant clock recovery capability. The N1076B iscontrolled via a USB connection to an N1000A or 86100D DCA-X mainframe or to a standalone PC
running N1010A FlexDCA software.

Figure 4. As shown in this block diagram, the N1076B recovers clock signals from NRZ and PAM4 input signals,
and provide jitter analysis capability (Option JSA) for additional insight and measurement accuracy.

Optical/Electrical Clock Recovery
The N1077A, N1077B, and N1078A provide instrument-grade clock recovery with adjustable loop
bandwidth and peaking on both electrical and optical signals up to 64 GBd. All are controlled via a USB
connection to an N1000A or 86100D DCA-X mainframe or to a standalone PC running N1010A
FlexDCA software.
The N1077A supports both multimode and singlemode operation, can be ordered with integrated
70-30 multimode and 50-50 single-mode splitters(option SMS) as shown in Figure 5 or with nosplitter (option SXT) as shown in Figure 8 andoperates up to 32.8 GBd.

The N1077B supports multimode and single-mode
operations and can be ordered with an integrated
70-30 splitter (option SMM) as shown in Figure 6
or with no splitter (option SXT) as shown in Figure
8 and operates up to 64 GBd.

The N1078A supports single-mode operation only
and can be ordered with an integrated 50-50
single-mode splitter (option S50) as shown in
Figure 7 or with no splitter (option SXT) as shownin Figure 8 and operates up to 64 GBd.

Supports both NRZ and PAM4 signal typeslProvides an easy method for using the electrical clock recovery solution with optical signals

11Characterize Next-generation Receivers andTransmitters
The wide data-rate range of Keysight’s clock recovery solutions allows testing of standards like
100/400G Ethernet and 64 GFC, while covering existing lower speed standards.

Figure 9. The N107x provides clock recovery capabilities for NRZ (top) and PAM4 (bottom) signals.

12

Recover clocks or clean-up clocks
The N107x provides clock signals for BERTs or oscilloscopes when access to appropriate clock signals
from the DUT is not possible. It can also act as a clean-up PLL for existing clocks with excessive intrinsic
jitter to allow accurate measurements.

Measure the real performance of clock-less devices
Accurate transmitter measurements are possible because of low intrinsic jitter, paired with tunable loop
bandwidth, selectable peaking, and good sensitivity. The N107x’s auxiliary clock output provides ultralow intrinsic random jitter of less than 100 fs RMS, making it the ideal companion for sampling scopes
equipped with a precision time base.

Perform more accurate jitter measurements and gain
greater insight into the root cause(s) of jitter
Jitter spectrum analysis (Option JSA) integrates a step generator and a low-noise, 14-bit ADC into theclock recovery design (see Figure 5, Figure 6, Figure 7, and Figure 8). The step generator and ADC
characterize the clock recovery PLL in real-time, providing FlexDCA with the information that isnecessary to calculate jitter at the input to the instrument. JSA uses this information to:l

Optimize the accuracy of random jitter measurements performed by Jitter mode (N1010100A R&D
Package)lEmulate an “ideal” software clock recovery (CR) response; implement Golden PLL per standardslAnalyze the jitter spectrum of clock and data signals using jitter magnitude vs. frequency graphslView the spectral distribution of low-frequency jitter and isolate jitter componentslPerform band limited (integrated) TJ/DJ/RJ measurements; user-specified start/stop frequencies

Figure 10. Jitter spectrum analysis (N107xA Option JSA) optimizes Jitter Mode accuracy (N1010100A R&D
Package), measures low-frequency jitter (phase noise), and provides insight into the root cause(s) of jitter.

14

Easily control all settings
The N107x clock recovery instrument is controlled via a rear-panel USB connection to an N1000A DCAX mainframe, or to a standalone PC (Win7/8/10) running Keysight Technologies N1010A FlexDCA
software (no license required for CR control).

Figure 11. Easily configure the N107x clock recovery data rate, loop bandwidth, and peaking using the N1010A
FlexDCA user interface running on an N1000A DCA-X mainframe or standalone PC.

Figure 12. The N107x clock recovery instrument is controlled via a rear-panel USB connection to an N1000A DCAX mainframe (bottom), or to a standalone PC (right) running the N1010A FlexDCA user interface.

15

Application Example
Figure 13 on page 17 illustrates clock recovery for sampling scope with high-bandwidth sampling heads
and a precision time base. Sampling scopes are the ideal choice for transmitter characterization whenhigh-bandwidth, low noise floor and low intrinsic jitter are required. The N107x, with its ultra-low jitter
auxiliary clock output, provides a clean sine wave for a precision time-base module or integrated
precision timebase enabling the most accurate measurements (precision timebase is not required). The
main recovered clock output, with its divide stages, triggers the front panel trigger input.
