It operates from a 3V to 3.6V supply and supports clock frequencies up to 133.33 MHz. The part is housed in an 8-SOIC package and is rated for the commercial temperature range of 0°C to 70°C, making it suitable for indoor equipment such as networking gear, servers, and office appliances where the ambient temperature stays within that band. ## 1:5 fanout and supply tolerance The 1:5 input-to-output ratio means a single reference clock drives five loads, which simplifies the clock tree layout and reduces the number of buffers needed. The 3V to 3.6V supply range aligns with standard 3.3V logic families; the 0.3V tolerance on the low side gives some headroom for rail droop under load. Because the outputs are single-ended (no differential signaling), the board designer must keep trace lengths matched and impedance-controlled to minimize skew between the five copies. ## Active lifecycle with ROHS3 compliance It is ROHS3 compliant, so it meets the latest EU restriction on hazardous substances and can be used in new designs without a waiver.","metaTitle":"CY2305SXC-1 Zero Delay Buffer, 133.33 MHz, 1:5 Fanout","metaDescription":"Cypress CY2305SXC-1 PLL-based zero delay buffer, 133.33 MHz max, 1:5 fanout, 3V–3.6V, 0°C–70°C, 8-SOIC.

The CY2305SXC-1 is rated for 0°C to 70°C (commercial), while the CY2305SXI-1HT is rated for -40°C to 85°C (industrial). Both parts share the same PLL-based zero delay buffer function, 1:5 fanout, 133.33 MHz maximum frequency, and 8-SOIC package. The industrial variant also comes in Tape & Reel packaging. Choose the SXC-1 for indoor, temperature-controlled environments; choose the SXI-1HT for applications that see freezing or elevated ambient temperatures."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY2305SXC-1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY2305SXC-1 when reusing this data.
