That 2:10 ratio means a single device can fan a reference clock to multiple loads — memory controllers, FPGAs, or ASICs — without adding separate fanout trees. The PLL cleans up jitter on the incoming clock and multiplies or divides the frequency internally, so the ten outputs stay phase-aligned even when the input is a noisy board-level trace. The differential input rejects common-mode noise picked up across a backplane or long cable; the single-ended LVTTL outputs drive standard CMOS loads directly. ## Supply, temperature, and package — the integration constraints Runs from a 2.97 V to 3.63 V rail — a 3.3 V ±10 % supply is the typical fit. Housed in a 52-lead LQFP with a 10x10 mm body. The bulk packaging means this is not tape-and-reel — confirm the handling method with your assembly house if the line expects reel-fed pick-and-place. ## Active lifecycle — what to expect on the sourcing side Listed as Active by Infineon. The RoHS status is non-compliant, so this is the legacy tin-lead version; if your BOM requires RoHS, the lead-free variant (suffix -AXI or similar) would be the correct drop-in.","metaTitle":"Infineon CY7B9945V-2AI RoboClock, 200 MHz, 2:10 Fanout","metaDescription":"Active PLL clock buffer, 200 MHz max, 2:10 LVPECL/LVTTL input to LVTTL output, 52-TQFP.
