Product details

What this zero delay buffer does

The CY2309ESXC-1 is a PLL-based zero delay buffer that takes one clock input and distributes it to nine outputs with near-zero propagation delay — the PLL aligns the output edges to the input so the clock tree sees no added skew. Rated to 133.33 MHz maximum frequency, it covers common processor, memory, and peripheral bus speeds up to that ceiling. The 1:9 fanout ratio lets a single source drive nine loads without an extra buffer stage.

Supply, package, and temperature fit

Operates from 3.0 V to 3.6 V, matching the 3.3 V logic rail found in most digital systems. It belongs in office equipment, appliances, and indoor telecom — not in engine bays, outdoor enclosures, or industrial floors where the ambient exceeds 70°C.

Active production — sourcing posture

Sourced per RFQ against your BOM quantity.

Frequently asked questions

Is CY2309ESXC-1 a zero delay buffer?

Yes — the type is listed as Zero Delay Buffer. It uses a PLL to deskew the output clocks so they align with the input, effectively eliminating propagation delay through the device.

What is the maximum frequency of CY2309ESXC-1?

The maximum rated frequency is 133.33 MHz. This is the ceiling for the PLL and output drivers; the input clock must stay at or below this value.

Does CY2309ESXC-1 have a PLL?

Yes — the PLL field is listed as 'Yes with Bypass'. The PLL is active in normal operation; the bypass mode lets the input clock pass through unmodified for test or low-jitter paths.

What is the closest functional second-source for CY2309ESXC-1?

The CY2305SXI-1HT comes in tape-and-reel packaging. If you need the 1:9 fanout, the CY2309ESXC-1 is the direct fit.
