Low skew clock buffer for Intel CPU and SRAM SO-DIMM clock trees
The Cypress CY2310ANZPVC-1 is a low skew clock driver designed to distribute a single reference clock to ten outputs with minimal propagation delay variation. It is a PLL-less buffer, meaning it does not multiply or synthesize frequencies — it simply fans out the input clock with low skew, making it suitable for timing architectures where clock alignment matters more than frequency generation. The part accepts LVCMOS or LVTTL inputs and delivers LVCMOS outputs, operating from a 3.135 V to 3.465 V supply. Its primary application is clock distribution for Intel CPU systems and SRAM SO-DIMM memory modules, where a clean, low-skew copy of the reference clock must reach multiple loads.
1:10 fanout — board-level distribution
With a 1:10 input-to-output ratio, a single reference clock drives up to ten loads. That covers the clock inputs of multiple SRAM chips on a SO-DIMM module, or the CPU and chipset clock inputs on a motherboard. Because the part is a PLL-less buffer, there is no jitter accumulation from a PLL loop — the output jitter is essentially the input jitter plus the buffer's additive jitter, which is typically lower than a PLL-based clock generator. The non-differential I/O (No/No for differential input and output) means it handles single-ended clocks only, not differential pairs like LVDS or HCSL.
Package and temperature grade
The CY2310ANZPVC-1 is offered in a 28-SSOP (5.30 mm body width) surface-mount package, supplier device package 28-SSOP. The operating temperature range is 0°C to 70°C (commercial grade), which limits it to indoor, temperature-controlled environments. It is not rated for automotive, industrial, or extended-temperature applications. The part is RoHS non-compliant (lead-bearing), so verify your assembly house's exemption or plan for a lead-free alternative if required.
Lifecycle and sourcing
The CY2310ANZPVC-1 is listed as Active in production status. The part is (not tape-and-reel), so plan for tube or tray handling in your pick-and-place setup.
