It accepts LVCMOS or LVTTL levels and reproduces them as LVCMOS/LVTTL outputs up to 200 MHz, making it a straightforward choice for clock trees in telecom line cards, industrial controllers, and FPGA-based systems where multiple clock domains share a single source. ## Supply voltage — two operating ranges The CY29947AI operates from a 2.375 V to 2.625 V supply or a 2.97 V to 3.63 V supply. Input and output levels must match the chosen supply rail — LVCMOS/LVTTL thresholds scale with VDD. ## Temperature grade and environment Rated for -40°C to 85°C, the CY29947AI is suited for industrial environments: outdoor telecom cabinets, factory-floor PLC racks, and base-station clock distribution where ambient temperatures stay below 85°C. The 32-TQFP package (7x7 mm) is a common footprint for surface-mount assembly, compatible with standard reflow profiles. ## Lifecycle and sourcing It is RoHS non-compliant, so verify your assembly's exemption allowance or check for a RoHS-compliant suffix variant if lead-free processing is required.","metaTitle":"CY29947AI Fanout Buffer, 200 MHz, 32-TQFP","metaDescription":"CY29947AI low-skew clock driver, 2:9 fanout, 200 MHz max, LVCMOS/LVTTL, -40 to 85°C, 32-TQFP.
