Its integrated PLL locks to the input and aligns the output edges, making it a fit for synchronous clock domains in networking gear, base stations, and test equipment where skew between multiple loads must be minimized. The 1:8 fanout covers most multi-load clock trees without needing external fanout buffers, and the 140 MHz ceiling handles Gigabit Ethernet, PCIe reference clocks, and mid-speed FPGA interfaces. ## Supply rail and temperature — where it fits The supply range is 2.97 V to 3.63 V, which maps to a regulated 3.3 V rail with ±10% tolerance. This is a narrow-range part — do not feed it from a 2.5 V or 5 V supply without a regulator. The operating temperature covers 0°C to 70°C, the commercial grade, limiting the W152-1G to indoor, temperature-controlled environments such as server rooms, telecom central offices, or lab instruments. For industrial enclosures or outdoor cabinets, a wider-temperature zero delay buffer would be needed. ## Package and footprint Housed in a 16-SOIC with 3.90 mm body width, the W152-1G uses a standard surface-mount footprint shared by many SOIC-16 logic and clock parts. The package is small enough for dense layouts but large enough for manual rework. No exposed pad — thermal dissipation is through the leads and board copper. ## RoHS non-compliance — what it means for the BOM The W152-1G is RoHS non-compliant, meaning it contains lead (Pb) above the 0.1% threshold. This triggers an exemption declaration under EU RoHS Directive 2011/65/EU and similar regulations in China, Korea, and California. If your design targets a lead-free assembly line or must meet full RoHS compliance, this part adds paperwork and may be rejected by your CM. For military, aerospace, or high-reliability applications where leaded solder is still preferred or exempted, this is not a blocker. ## Lifecycle and sourcing posture That means no last-time-buy scramble and no forced redesign for the foreseeable future. For dual-sourcing or a second-source evaluation, the CY2305SXI-1HT from Cypress offers a similar zero delay buffer function with 1:5 fanout and industrial temperature range, but verify pin compatibility against your layout before substituting.","metaTitle":"W152-1G Zero Delay Buffer, PLL, 140 MHz, 16-SOIC","metaDescription":"W152-1G Spread Aware™ zero delay buffer with integrated PLL, 1:8 fanout, 140 MHz max, 2.97V–3.63V supply, 16-SOIC.
