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.","metaTitle":"CY2309ESXC-1 Zero Delay Buffer – Infineon – 133.33 MHz","metaDescription":"CY2309ESXC-1 from Infineon: PLL-based zero delay buffer, 133.33 MHz max, 1:9 fanout, 3.0-3.6V, 16-SOIC.

It uses a PLL to deskew the output clocks so they align with the input, effectively eliminating propagation delay through the device."},{"question":"What is the maximum frequency of CY2309ESXC-1?","answer":"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."},{"question":"Does CY2309ESXC-1 have a PLL?","answer":"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."},{"question":"What is the closest functional second-source for CY2309ESXC-1?","answer":"The CY2305SXI-1HT comes in tape-and-reel packaging.
