Differential ECL Clock VSCO
Sine Wave and ECL VCSOs
Sawtek proudly offers two Voltage-Controlled SAW Oscillator
(VCSO) products ideally suited to the most demanding broadband
access applications. Our single-ended sine wave oscillator is
maximized for SONET, LMDS/MMDS point-to-point/multi-point
microwave and software radio designs. Sawtek’s dif ferential
output Emitter Coupled Logic (ECL) clock is perfect for the low
jitter requirements of SONET, Ethernet and network servers.
Both products generate frequencies fundamentally, so no
subharmonics are produced which enhances their ability to
reduce jitter. With 600 ppm of typical tuning range, the units
are able to tune back to center frequency over a variety of
conditions such as temperature, load pulling, voltage pushing,
set-on and aging.
Single-Ended Sine W ave VCSO
• Frequencies from 300 MHz to 2.5 GHz with 622.08 MHz,
666.51 MHz and 2.488 GHz being standard frequencies
• Surface Transverse W ave (STW) resonator technology offers
low phase noise, and extremely low noise floors to insure
exceptional high frequency jitter performance (< 5 fS RMS)
• Low g-sensitivity versions available up to 5x10-10/g
• These narrow-band VCSO’s are designed for use in phase
locked loop applications
Differential ECL Clock VCSO
• Frequencies from 600 MHz to just over 1 GHz with standard
frequencies at 622.08 MHz and 666.51 MHz
• STW resonator technology offers very low jitter performance
at high fundamental frequencies (< .3 pS RMS)
• These narrow-band ECL VCSO’ s are designed for use in
phase locked loop applications
