Which Crystal Oscillator Output Signal Is Best for Your Application?
Content

 

 

 

 

 

 

 

 

 

 

The common signal types are broken down into two categories: single-ended and differential logic outputs. Each category includes several types of output signals. 

Single-Ended

  • Sinewave and clipped sinewave
  • CMOS (complementary metal oxide semiconductor)
  • HCMOS (high speed CMOS)
  • LVCMOS (low voltage CMOS)
  • TTL (transistor-to-transistor logic)

Differential Logic

  • ECL (emitter coupled logic)
  • PECL (positive emitter coupled logic)
  • LVPECL (low voltage PECL)
  • CML (current-mode logic)
  • LVDS (low voltage differential signaling)
  • HCSL (high speed current steering logic)

Which Oscillator Output Signal Type Is Right for Your Needs?

Differential vs. Single Ended

  • Sinewave generally offers the best phase noise, followed by CMOS, then differential.
  • Higher frequencies tend to require differential signals.
  • Differential signals have better rise and fall time.
  • Differential signals are more resistant to common mode noise.
  • Differential signals have  fewer EMI concerns.

Ease of Use

  • LVDS requires only a single resistor at the receiver, while LVPECL requires termination at both transmitter and receiver ends.
  • LVDS

Fastest Speed

  • LVDS is faster than CMOS. HCSL and LVPECL are faster but can require more power.

Lowest Power Consumption

  •  LVPECL is faster but consumes more power, so we recommend using CMOS or LVDS for low power consumption.

Best Jitter Performance

  • You can get the best jitter performance from LVPECL, followed by LVDS, and then CMOS.
