Agilent / Keysight N1076B Electrical Clock Recovery 125 MBd to 64 GBd data rate range

The Keysight N1076B Electrical Clock Recovery module extracts clock signals from high-speed electrical data streams with exceptional precision. Supporting NRZ and PAM4 formats across 125 MBd to 64 GBd, it delivers standards-compliant clock recovery using a Golden PLL architecture optimized for timing analysis in serial data applications.

– Technical Specifications

• Data Rate Range: 125 MBd to 64 GBd (continuous)
• Signal Types: Electrical NRZ and PAM4
• Clock Recovery Method: Standards-compliant Golden PLL
• PLL Bandwidth: Adjustable, up to 20 MHz
• Peaking: Adjustable
• Input Voltage: ±500 mV maximum
• Control Interface: USB 2.0 or 3.0

– Key Features

The N1076B incorporates a variable equalizer for locking onto degraded signals—useful in closed-eye measurement scenarios. Jitter Spectrum Analysis (JSA) capability provides direct insight into jitter root causes, enabling root-cause failure analysis in serial link validation.

Adjustable PLL bandwidth up to 20 MHz and variable peaking give engineers fine control over clock recovery behavior across wide data rate ranges. The module handles both standard and impaired signal conditions without requiring external components.

– Typical Applications

• High-speed serial signal integrity characterization
• Timing and jitter analysis on degraded data streams
• Standards-compliant PLL bandwidth and peaking measurements
• PAM4 modulation format clock extraction
• PCI Express and similar protocol testing

– Compatibility & Integration

The N1076B integrates with Keysight’s N1000A and 86100D DCA-X mainframes via USB connection, or operates standalone on PCs running N1010A FlexDCA software. Advanced measurement applications leverage the N1010300A FlexPLL Application software and N1081PLCA PCI Express PLL Test Application for compliance and characterization workflows. Minimum firmware version N1076B A.06.00 is required.
