oscillator that achieves superb jitter and stability
over a broad range of operating conditions and
frequencies. The output clock signal, generated
internally with a non-PLL oscillator design, is
compatible with JESD8-7 logic levels. The device,
available on tape and reel, is contained in a 7.0
x 5.0mm surface-mount ceramic package.
