Agilent/Keysight 10468A

The Keysight 10468A is a 5V PECL clock pod module designed to interface pattern generator and logic analyzer systems with dedicated clock signal distribution. It has ECL-compatible clock inputs and outputs, supporting frequencies up to 300 MHz with adjustable delay control. Each pattern generator module or 1682xA logic analyzer operating as a master requires one clock pod to enable synchronization and pattern recognition across the measurement system.

Technical Specifications

• Clock Output: 10EL90 (5 V) topology with 348 Ω pulldown to ground and 42 Ω series impedance


• Clock Output Rate: DC to 300 MHz maximum


• Clock Output Delay: Maximum 11 ns, adjustable in 9 steps


• Clock Input: 100EL91 PECL (5 V), no termination required


• Clock Input Rate: DC to 300 MHz


• Pattern Input: 100EL91 PECL (5 V), no termination; unconnected pins default to logic 0


• Clock-in to Clock-out Propagation Delay: Approximately 30 ns


• Pattern-in to Recognition Delay: Approximately 15 ns + 1 clock period

Key Features

• Single-pod configuration for one pattern generator module or one portable logic analyzer master


• Adjustable output delay in 9 discrete steps for timing alignment


• ECL/PECL logic levels throughout ensure compatibility with high-speed digital test systems


• No external termination needed on clock and pattern inputs

Typical Applications

• Multi-module pattern generation systems requiring synchronized clock distribution


• Portable logic analyzer setups (1682xA series) with external timing references


• High-speed digital circuit characterization and functional testing

Compatibility & Integration Designed for the Keysight 16720A pattern generator module family. The Keysight 10498A lead set is required for connection and should be ordered concurrently with the 10468A.
