Applications
The VS-501-0074-1000M0 serves as a precision 1000 MHz clock source in high-speed serial communications equipment, including 10 Gbps Ethernet switches, OC-48/STM-16 SONET/SDH line cards, and SerDes-based backplane interconnects where low-phase-noise clocking is critical. Its voltage-control input allows integration into phase-locked loop circuits for clock synthesis and jitter filtering in FPGA-based signal processing platforms. RF test instruments and microwave synthesizers also use this VCSO as a stable GHz-range reference to achieve tight frequency tolerance across temperature.

Frequently Asked Questions
What is the output frequency of the VS-501-0074-1000M0, and what communication standards does it serve?
The VS-501-0074-1000M0 outputs exactly 1000 MHz (1 GHz), making it a suitable reference clock for 10 Gbps Ethernet (10GbE), OC-48 SONET line cards, and PCI Express Gen 2 SerDes links that require a stable GHz-range clock with low phase noise.
How does the voltage-control input on the VS-501-0074-1000M0 enable PLL integration?
The voltage-control (Vctrl) input shifts the oscillator frequency proportionally to an applied DC voltage, allowing the VS-501-0074-1000M0 to act as the VCO in a phase-locked loop; the PLL feedback corrects frequency drift, achieving sub-picosecond jitter suitable for 1000 MHz clock-recovery applications.
What supply voltage does the VS-501-0074-1000M0 require, and can it run directly from a 3.3 V rail?
The VS-501-0074-1000M0 operates from a 3.3 V supply, which is a standard power rail on modern FPGA boards and network switch line cards, allowing direct connection without a dedicated oscillator regulator and simplifying power distribution on GHz-speed PCB designs.
Why is SAW resonator technology used in the VS-501-0074-1000M0 instead of a standard crystal oscillator at 1 GHz?
Conventional AT-cut crystal resonators have practical frequency limits around 200 MHz to 300 MHz; above that, surface acoustic wave (SAW) resonators are necessary to achieve fundamental-mode resonance at 1000 MHz, providing lower phase noise and better frequency stability than overtone crystal designs at GHz frequencies.
