It takes one clock input and distributes it to eight LVPECL outputs with minimal added skew between channels. That 1:8 ratio means a single device can feed eight destination ICs from one source, saving board space versus daisy-chaining multiple smaller buffers. Input flexibility covers LVDS, LVPECL, and LVTTL, so it can sit behind an oscillator, a PLL output, or a logic-level clock source without extra level translation. Outputs are differential LVPECL, the standard for high-speed clock distribution in telecom and data-comm systems where noise margin matters. Rated for 350 MHz maximum frequency. The differential input and output path gives common-mode rejection on the input side, which helps when the clock source is across a backplane or cable. ## Supply rails and temperature — where this part lives Supply range is 3.135 V to 3.465 V. The industrial temperature grade of -40°C to 85°C covers outdoor telecom cabinets, factory floor enclosures, and base station equipment where the ambient isn't climate-controlled. Package is a 38-TSSOP, body width 4.40 mm. The single-circuit design means one buffer per package; no dual or quad options to confuse the BOM. ## Lifecycle and sourcing reality The RoHS status shows non-compliant. For RoHS-mandated builds, you'll need to check if an equivalent RoHS-compliant variant exists in the family.","metaTitle":"CY2DP818ZI-2 Fanout Buffer, 350 MHz, 1:8 LVPECL Output","metaDescription":"CY2DP818ZI-2 low skew clock driver, 350 MHz max, 1:8 fanout, LVDS/LVPECL/LVTTL input, LVPECL output.
