Frequently Asked Questions

What are the advantages of using a timing module vs discrete oscillators?

Timing modules offer advantages over discrete oscillators: 1) Single reference - one crystal or reference input generates all clocks. 2) Synchronized outputs - all clocks are phase-locked and synchronized. 3) Frequency synthesis - generate any frequency from single reference. 4) Multiple outputs - 2 to 12+ outputs from one device. 5) Reduced BOM - fewer components, lower inventory. 6) Better jitter performance - integrated PLL optimization. 7) Advanced features - spread spectrum, redundancy, fail-safe. 8) Simplified design - complete solution in one device. Disadvantages: Higher cost than single oscillator, Single point of failure. For systems requiring multiple related clocks, timing modules simplify design and improve performance.

Use timing modules for multi-clock systems. Use discrete oscillators for single-clock applications.

What is spread spectrum clocking and when should I use it?

Spread spectrum clocking (SSC) modulates the clock frequency to reduce EMI (Electromagnetic Interference). How it works: The clock frequency is varied slightly (typically ±0.5% to ±2%) at a low rate (30kHz to 60kHz). This spreads the energy over a wider frequency range, reducing peak emissions. Benefits: Reduced EMI by 6dB to 20dB, Easier EMC compliance, Reduced shielding requirements. When to use: High-speed digital systems, Consumer electronics with EMC requirements, Systems with sensitive analog circuits, Cost-sensitive designs where shielding is expensive. Spread spectrum is commonly used in: PCs and laptops, Displays and TVs, Networking equipment, Automotive electronics. Most timing modules offer optional spread spectrum.

Enable spread spectrum for EMI-sensitive applications. Contact us for SSC recommendations.

How do I select the right number of outputs?

Selecting the number of outputs: Count your clock requirements - list all devices needing clocks. Group by frequency - identify which devices can share the same frequency. Consider redundancy - add extra outputs for fail-over if needed. Future expansion - add 20-30% extra for design margin. Common configurations: 2-4 outputs - small systems, single board. 6-8 outputs - medium systems, multiple boards. 10-12+ outputs - large systems, servers, telecom. Output types: LVCMOS for general digital, LVDS/LVPECL for high-speed, Differential for noise immunity. Mixed output types available on some modules. Choose a module with slightly more outputs than currently needed for future flexibility.

Count clock requirements and add margin. Contact us for multi-output recommendations.

What is clock jitter and how does it affect my system?

Clock jitter is the variation in clock edge timing from the ideal position. Types of jitter: Period jitter - variation in clock period. Cycle-to-cycle jitter - variation between adjacent cycles. Phase jitter (RMS) - integrated phase noise. Long-term jitter - variation over many cycles. Effects on systems: Digital systems - reduced timing margin, potential errors. ADC/DAC - reduced SNR, lower effective bits. Communication systems - increased bit error rate. High-speed interfaces - reduced eye opening. Typical jitter specs: Standard oscillators - 1ps to 10ps RMS. Low-jitter oscillators - 0.1ps to 1ps RMS. Timing modules with PLL - 0.5ps to 3ps RMS depending on design. For high-speed SERDES, use low-jitter timing solutions.

Select low-jitter timing for high-speed interfaces. Contact us for jitter requirements.

Can timing modules accept different input references?

Yes, timing modules support various input references: Crystal input - 10MHz to 50MHz fundamental crystal. Clock input - CMOS, LVDS, or LVPECL clock signal. Frequency range - modules accept wide input frequency range. Automatic detection - some modules auto-detect input type. Redundant inputs - switch between primary and backup references. Input requirements: Frequency accuracy - typically ±100ppm input tolerance. Amplitude - CMOS (0-VDD), differential (0.2V to 1.2V). Duty cycle - 40% to 60% typical. Input impedance - 50 ohms or high-Z options. Benefits: Design flexibility - use crystal or external clock. Redundancy - backup reference for reliability. System integration - accept clock from another system. Check datasheet for specific input requirements and capabilities.
