PLL-based zero delay buffer for tight clock alignment
The W163-05GT is a PLL-based zero delay buffer from Infineon's Spread Aware™ series, designed to deskew a reference clock with near-zero propagation delay. It accepts a single-ended input and fans it out to five outputs (1:5 ratio) at up to 133 MHz, making it a fit for synchronous systems where clock skew between loads must be minimized.
Supply rail and temperature range for board fit
Operating from a 2.97V to 3.63V supply, the part aligns with a nominal 3.3V rail — the 0.33V tolerance covers ±10% regulation, so a clean 3.3V supply from a regulator or LDO is sufficient.
Package and reflow considerations for the shop floor
Housed in an 8-SOIC (0.154-inch width, 3.90 mm body) surface-mount package, the W163-05GT uses a standard footprint that places without tombstoning risk on typical reflow profiles. The package is, not tape-and-reel — check your pick-and-place feeder setup; bulk tubes may require manual loading or a tube feeder.
Active production and compliance flag
Note that the part is RoHS non-compliant — it contains lead (Pb) above the 0.1% threshold, so it cannot be used in EU RoHS-regulated assemblies without an exemption. For RoHS-required builds, a lead-free alternative such as the CY2305SXI-1HT may be considered (see FAQ).
