The 2:18 input-to-output ratio means you can feed two independent clock sources into the buffer and select between them, while the eighteen outputs can drive multiple loads — useful for backplane clock distribution or synchronising several ASICs from a single oscillator. Because the part is specified as a low-skew driver, the propagation delay variation between any two outputs stays tight, which matters when the receiving devices have tight setup-and-hold windows. ## Temperature grade and deployment environment Rated for 0°C to 70°C, the CY29940AC is intended for temperature-controlled environments. It is not specified for extended-temperature operation. ## Lifecycle and sourcing The CY29940AC carries an Active lifecycle status, meaning Cypress (now part of Infineon) continues to manufacture it. The part is RoHS non-compliant per the original release, so verify your assembly line's solder alloy and reflow profile if you are running lead-free processes.","metaTitle":"CY29940AC Fanout Buffer, 200 MHz, 2:18, 32-LQFP","metaDescription":"CY29940AC low skew clock driver from Cypress. 200 MHz max, 2:18 fanout, LVCMOS/LVPECL/LVTTL input, 32-LQFP.
