• Pb-free & RoHS compliant
• Industrial temperature range
Product Description
The LD series 3.3V, 156.25MHz crystal
clock oscillator achieves superb jitter for
10GbE applications. The output clock signal,
generated internally with a custom 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.
