The W163-15GT is a PLL-based zero delay buffer from Infineon's Spread Aware series, designed to regenerate a clean clock output with deterministic phase alignment from a single reference input. It accepts a single-ended clock up to 133 MHz and fans it out to five outputs, all phase-aligned to the input within the PLL's capture range. The internal PLL can be bypassed when you need to pass through an external clean clock without jitter cleaning — useful during system debug or when a spread-spectrum reference is already compliant. The supply voltage range of 2.97V to 3.63V covers standard 3.3V rails with margin for ripple; the commercial temperature grade of 0°C to 70°C limits it to indoor, climate-controlled equipment — think servers, telecom line cards, test gear, or office peripherals. Not a fit for an engine bay or a rooftop radio.
Lifecycle and compliance – active but RoHS-flagged
That said, it is listed as RoHS non-compliant, which means it contains lead (Pb) above the 0.1% threshold. For EU/UK shipments or any product that must meet RoHS, this part requires an exemption or a waiver. If your BOM is RoHS-mandated, you will need to either secure an exemption or evaluate a RoHS-compliant second source. The package is an 8-SOIC, standard 0.154-inch width, 3.90 mm body — a common footprint that is easy to hand-solder or rework with a basic iron. No hot-air station needed, which makes it a field-swappable part for a repair technician.
