Product details

What this clock driver does on a DIMM

The CY2318BNZPVI-11 is a low skew clock driver from Cypress, designed specifically for SDRAM DIMM applications. It takes a single clock input and distributes it to 18 outputs with minimal skew between channels, running at up to 133 MHz. The integrated PLL cleans up jitter on the incoming clock and generates the low-skew fanout needed to drive multiple memory devices on a DIMM reliably.

Note the RoHS non-compliant status — this part contains lead in the solder finish and is not exempt for all applications. If your assembly line or end-market requires RoHS compliance, factor in a waiver or look for a lead-free variant.

Frequently asked questions

Is CY2318BNZPVI-11 obsolete or end-of-life?

No, the manufacturer lifecycle status is Active. There is no announced end-of-life for this part.

What is a low skew clock driver?

A low skew clock driver takes one clock input and generates multiple output clocks with tightly controlled propagation delay differences (skew) between outputs. This ensures all memory devices on a DIMM see the clock edge at nearly the same time, which is critical for setup and hold timing at high frequencies.

What is the difference between a clock buffer and a clock driver?

A clock buffer typically provides simple fanout without PLL or skew control. A clock driver like the CY2318BNZPVI-11 includes a PLL to clean jitter and actively manages output skew, making it suitable for high-speed memory interfaces where timing margin is tight.
