W152-12G

Overview

The W152-12G is an eight-output zero-delay buffer manufactured by Infineon Technologies, formerly Cypress Semiconductor. It utilizes a Phase-Locked Loop (PLL) to generate eight copies of a reference signal with outputs in phase with the input. The device supports Spread Aware technology for SSFTG signals and includes internal dividers for frequency multiplication options such as /2, x2, or x4. It operates within a supply voltage range of 2.97 V to 3.63 V, typically at 3.3 V, and functions at frequencies between 15 MHz and 140 MHz. The component is housed in a 16-pin SOIC package.

Feature Summary

• Eight-output zero-delay buffer with PLL-based synchronization
• Spread Aware design compatible with SSFTG reference signals
• Internal frequency division/multiplication options (/2, x2, x4)
• Three-state output capability for bus isolation

Applications

• Clock distribution in high-speed digital systems
• Synchronization of multiple components requiring zero-skew timing
• Frequency synthesis applications using internal dividers

Procurement Notes

The W152-12G is listed as obsolete or discontinued by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors. Verify RoHS compliance status, as some sources indicate non-compliance for this specific part number. Confirm lead times and authenticity through authorized channels due to its end-of-life status.

Selection Notes

Select the W152-12G when eight synchronized clock outputs are required with minimal skew relative to the input reference. Ensure the application frequency falls within the 15 MHz to 140 MHz range. Consider the 16-pin SOIC package constraints and verify if the extra strength output drive (-12 suffix) meets load requirements. Check for alternative active parts if long-term supply stability is critical.

Part Context

This component belongs to the W152 family of Spread Aware zero-delay buffers. It was originally developed by Cypress Semiconductor before the company's acquisition by Infineon Technologies. The -12 suffix denotes specific output drive characteristics compared to other variants in the series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official replacement guides from Infineon or evaluate similar zero-delay buffers with compatible pinouts and electrical specifications.
