Application Specific Clock/Timing Part Context

The ICS954201BGLFT belongs to the IDT/Renesas CK410M family of clock synthesizers. This product line was acquired by SiTime, with full transition expected by the end of 2026. Documentation remains available via Renesas.com until that date. The specific part number indicates a 56-TSSOP package variant within this mobile-focused timing hub series.

Application Specific Clock/Timing Replacement Considerations

SiTime has acquired the Renesas timing product portfolio. New designs should consult SiTime.com for equivalent solutions or support. Existing inventory may be sourced through remaining distributors, but long-term availability is limited as the product transitions to the SiTime ecosystem.
