Product Description
The LD Series 2.5V crystal clock oscillator
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 LVDS logic levels. The device, available
on tape and reel, is contained in a 5.0 x
3.2mm surface-mount ceramic package.
