It accepts LVCMOS, LVPECL, or LVTTL inputs and drives LVCMOS or LVTTL loads at up to 200 MHz. The 2:18 fanout ratio lets a single device feed multiple synchronised destinations — useful on a board where a master clock must reach several FPGAs, ASICs, or high-speed converters without introducing edge misalignment. ## Supply and temperature — what they mean for the BOM The CY29940ACT runs from either a 2.375 V to 2.625 V rail or a 3.135 V to 3.465 V rail. The operating temperature range is 0°C to 70°C. ## Differential input — yes or no The differential input flag is marked Yes/No, which means the part can handle both single-ended (LVCMOS/LVTTL) and differential (LVPECL) input signals. That flexibility matters when the source is a differential oscillator or a single-ended clock generator — the same buffer works for either topology. ## Lifecycle and sourcing The CY29940ACT carries an Active lifecycle status per the manufacturer. The part is RoHS non-compliant, so if your assembly line is RoHS-only, flag it for a waiver or look at the lead-free variant. Submit an RFQ for your required quantity and target delivery window.","metaTitle":"CY29940ACT Fanout Buffer, 200 MHz, 2:18, 32-LQFP","metaDescription":"CY29940ACT low skew clock driver, 200 MHz max, 2:18 fanout, LVCMOS/LVPECL/LVTTL inputs, 32-LQFP.
