New Low Jitter, J-Type VCXO's To 170 MHz

Surface Mount Temperature Compensated Crystal Oscillators (TCXO's) For Communications Applications Norwalk, CT... Vectron International (VI) has introduced a series of new low jitter, Voltage Controlled Crystal Oscillators (VCXOs) available at frequencies from 1.024 MHz to 170 MHz  

The new J-type voltage controlled crystal oscillators expand VI's advanced VCXO performance capabilities while adhering to a package footprint compatible with the industry-common surface mount J-lead package.

Features include:
  • Output Frequencies from 1.024 MHz to 170.000 MHz
  • +3.3 or +5.0 volt options
  • Small 14mm x 9mm J-type Package
  • CMOS or PECL Outputs
  • Excellent Jitter Performance
  • Tri-State output (CMOS) Enable/Disable (PECL)
Typical Jitter performance is < 0.5 ps rms (12k Hz to 20 MHz) at the output frequency for the CMOS version and <1 ps rms for the PECL option. The units are CMOS or PECL compatible with an input of +3.3 Vdc or +5.0 Vdc. The device is packaged in a 6 pin J-lead ceramic package and is hermetically sealed with a grounded conductive lid.

The new J-Type oscillators are ideal for clock smoothing and frequency translation in SONET/SDH, ATM, DSLAM and other telecommunication applications.

Vectron International designs, manufactures and markets frequency generation and control products using the very latest techniques in both standard crystal and surface acoustic wave (SAW) based designs from DC to microwave frequencies. Products include crystals and crystal oscillators; SAW filters and components; and clock and data recovery products used in telecommunication and data communication applications.
