The 1:4 ratio means one crystal oscillator feeds four output copies, each with spread-spectrum modulation. If your design needs more than four clock outputs, you will need a separate fanout buffer or a second generator. The PLL is always engaged; there is no bypass mode for a clean, non-spread clock. ## Temperature grade and environment — commercial only Rated for 0°C to 70°C ambient, this part is intended for indoor, temperature-controlled environments such as office equipment, desktop PCs, and servers. Do not use in industrial enclosures, automotive cabins, or outdoor telecom cabinets without active cooling that keeps the ambient within range. The 28-SSOP package is a standard surface-mount footprint, but the 5.30 mm body width is narrower than a typical SOIC-28 — verify the land pattern against your PCB layout. ## Lifecycle — active, no end-of-life risk Cypress (now part of Infineon) lists this part as Active with no announced discontinuation.","metaTitle":"Cypress CY28506OC Spread Spectrum Clock Generator, PLL","metaDescription":"Cypress CY28506OC spread spectrum clock generator with integrated PLL, 1:4 fanout, max 166.7 MHz, 3.3V supply, 28-SSOP.

For a functional alternative with a similar PLL-based clock generation role, the CY2305SXI-1HT is a fanout buffer and zero-delay buffer, but it lacks spread-spectrum modulation and has a different output count (1:5) and temperature range (-40°C to 85°C).
