Product advantages
xcellent high-speed and low jitter performance
The CO32P6 series provides differential LVPECL output and ultra-low phase jitter, ensuring better signal integrity compared to single ended oscillators in serial data links above gigabit level.
Highly integrated differential output
No need for external clock buffers or signal conditioning chips, significantly saving board level space and material quantity compared to traditional " oscillator+separate buffer" solutions.
certificate
The LVPECL Crystal Oscillator 3225 CO32P6 series is RoHS/REACH-certified, lead-free, and halogen-free.
FAQ
Q1: How to Test this Thermistor-Compensated LVPECL Oscillator?
A: 1) Verify output frequency accuracy and stability (±ppm) over the entire temperature range.
2) Measure differential output waveform integrity (amplitude, rise/fall time) under load.
3) Confirm tri-state function works; if no output, check Enable pin bias and power supply noise.
Q2: Common Issues & Solutions for This Oscillator
A: Issue 1: Excessive Phase Jitter or Unclean Output Waveform
Cause: Improper differential termination, excessive power supply noise, or poor PCB layout.
Fix: Ensure 50Ω parallel termination to Vcc-2V is placed close to the receiver. Improve power decoupling with low-ESL capacitors. Route differential pairs with controlled impedance.
Issue 2: Frequency Output is Incorrect or Drifts Beyond Spec
Cause: Internal compensation circuit failure, damaged crystal element, or operating outside specified load conditions.
Fix: Replace the unit. Verify the input voltage and load are within the absolute maximum ratings and recommended operating conditions.
