Rated up to 200 MHz, it handles common base-station or switch fabric clocks without reclocking. One input can be differential (the other is single-ended), giving flexibility for mixed-signal boards where a clean LVPECL source feeds the distribution. ## Supply rails and temperature grade No exposed thermal pad — junction-to-ambient thermal performance follows the JEDEC JESD51-7 board profile. ## Compliance and sourcing reality Marked as RoHS non-compliant — the lead-free exemption does not apply. This limits its use on lines requiring full RoHS-10 compliance unless a waiver is in place.","metaTitle":"CY29940AC-1 Fanout Buffer, 200 MHz, 32-LQFP","metaDescription":"CY29940AC-1 Fanout Buffer (Distribution) from Infineon. 200 MHz max, 2:18 I/O ratio, 0°C to 70°C.
