CY2545QC009 Equivalent & Substitute Parts

Part Overview

The CY2545QC009 is a Fanout Distribution, Fractional N Synthesizer, Multiplexer, and Spread Spectrum Clock Generator IC manufactured by Infineon Technologies. This device operates at a maximum frequency of 166MHz and integrates a Phase-Locked Loop (PLL) with bypass capability, supporting both clock and crystal inputs with clock outputs. The component is housed in a 24-UFQFN Exposed Pad surface mount package and is currently in active production status with ROHS3 compliance. Identifying equivalent substitute parts is essential for supply chain continuity, inventory optimization, and design flexibility when the primary part becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitution eligibility for the CY2545QC009 is determined by strict equivalence across the following critical parameters:

Functional equivalence requires identical device type classification: Fanout Distribution, Fractional N Synthesizer, Multiplexer, and Spread Spectrum Clock Generator functionality.

Electrical compatibility mandates matching specifications: maximum frequency of 166MHz, supply voltage range of 2.25V to 3.6V, operating temperature range of 0°C to 70°C, PLL with bypass capability, clock and crystal input support, clock output configuration, 4 circuits, and 2:8 input-to-output ratio.

Mechanical compatibility requires identical packaging: 24-UFQFN Exposed Pad surface mount package with 24-QFN (4x4) supplier device package designation.

Regulatory and compliance alignment requires ROHS3 compliance, REACH Unaffected status, and MSL 3 (168 Hours) moisture sensitivity level.

Only parts meeting all these criteria are classified as parametric equivalents and direct substitutes.
