Product Specifications

Technical details and manufacturing context for Delay line

Definition
A delay line is a critical component within a timing generator that creates a controlled time delay for electrical signals, enabling precise synchronization, signal alignment, and timing adjustments in electronic circuits and systems.
Working Principle
It operates by propagating an electrical signal through a physical medium (like a length of coaxial cable, a surface acoustic wave device, or a digital memory buffer) where the signal's travel time through the medium creates the desired delay. The delay is determined by the physical length and propagation velocity of the medium or by digital clock cycles in electronic implementations.
Common Materials
Copper, Dielectric Insulator, Semiconductor Substrate
Technical Parameters
  • The precise time delay introduced to the signal, typically ranging from nanoseconds to microseconds. (ns) Customizable
Components / BOM
  • Transmission Line/Medium
    The core element (e.g., coaxial cable, SAW substrate, digital buffer) through which the signal propagates to create the delay.
    Material: Copper, Piezoelectric Crystal, Silicon
  • Input/Output Connectors
    Interface points for connecting the delay line into the larger circuit of the timing generator.
    Material: Brass, Gold-plated contacts
  • Shielding/Casing
    Protects the internal components from electromagnetic interference and physical damage.
    Material: Aluminum, Steel
Engineering Reasoning
1 ns - 100 μs delay range, 0-5 V input signal amplitude, -40°C to +85°C operating temperature
Signal propagation delay deviation > ±5% from nominal value, insertion loss > 3 dB, group delay ripple > 10%
Design Rationale: Dielectric breakdown at >50 V/μm electric field strength, thermal expansion mismatch (CTE difference > 10 ppm/°C) causing mechanical stress fractures, electromigration at current density > 10^6 A/cm²
Risk Mitigation (FMEA)
Trigger Electrostatic discharge (ESD) event exceeding 2 kV HBM
Mode: Dielectric breakdown in transmission line substrate
Strategy: Integrated ESD protection diodes with 0.7 V forward voltage clamping
Trigger Thermal cycling between -55°C and +125°C at 10°C/min rate
Mode: Interconnect fracture due to coefficient of thermal expansion mismatch
Strategy: Gold-tin eutectic solder (80Au-20Sn) with 280°C melting point for stress relief
