Clock fanout for high-speed backplanes
The CY2DP3110AI is a low-skew clock driver from Cypress, a fanout buffer that takes one or two differential ECL or PECL inputs and distributes them to ten outputs. It handles clock rates up to 1.5 GHz, which puts it in the range for SONET/SDH, 10G Ethernet, and high-speed ADC/DAC reference clocks. The 2:10 ratio means you can feed a primary and redundant clock source and fan out to ten loads without an external splitter. All signal paths are differential, both input and output. That means the part rejects common-mode noise that would corrupt a single-ended clock on a long backplane trace.
RoHS non-compliant per the original release — if your BOM requires RoHS, verify the suffix or look for a lead-free variant.
