The 2:10 input-to-output ratio means you can feed two independent clock sources (say, a primary oscillator and a backup) and route either to up to ten loads, or split the outputs between the two inputs. Because the part is single-ended only (no differential I/O), it is best suited for single-ended clock trees driving CMOS loads — not for LVDS or LVPECL fanout. ## Lifecycle and sourcing It is RoHS non-compliant per the original release, so verify your assembly house's exemption policy if you need lead-free.","metaTitle":"CY29946AIT Fanout Buffer, Divider, Mux, 200 MHz, 32-TQFP","metaDescription":"CY29946AIT low-skew clock driver: 2:10 fanout, 200 MHz max, LVCMOS/LVTTL I/O, dual 2.5V/3.3V supply, -40 to 85°C.
