9ERS3165BGILFT

Overview

The 9ERS3165BGILFT is a clock synthesizer and jitter cleaner manufactured by Renesas Electronics, belonging to the 9ERS3165B series. It serves as an embedded CK505 compatible clock solution designed for industrial temperature applications. The device features 21 outputs housed in a TSSOP-64 package with surface mount installation. It supports a maximum input frequency of 14.318 MHz and operates within a temperature range of -40°C to +85°C. This component integrates internal voltage regulation without requiring external pass transistors.

Feature Summary

• CK505 Compatible: Provides embedded clock signals compatible with CK505 specifications.
• Integrated Regulation: Includes an integrated 33-ohm series resistor on differential outputs (Zo=50Ω) and does not require external pass transistors for voltage regulation.
• Spread Spectrum Modulation: Supports spread spectrum modulation with a default 0.5% down spread.
• Flexible Output Configuration: Offers selectable SRC differential push-pull pairs, single-ended outputs, CPU differential low power push-pull pairs, and specific frequencies for PCI, USB, and REF.

Applications

• Industrial embedded systems requiring CK505 compatibility.
• Clock distribution for PCIe Gen2 specification compliance.
• Systems utilizing 14.318 MHz crystal inputs for frequency tuning.

Procurement Notes

The 9ERS3165BGILFT is listed as an End-of-Life (EOL) product by Renesas Electronics. Distribution availability is restricted, with some sources indicating limited supply or discontinuation notifications effective around May 2025. Verification of current stock status and alternative sourcing strategies is required before procurement planning.

Selection Notes

Select this component when a CK505-compatible clock synthesizer is needed for industrial environments (-40°C to +85°C). Ensure the design accommodates the TSSOP-64 package and utilizes an external 14.318 MHz crystal with load caps. Note that due to its EOL status, long-term supply continuity should be evaluated against newer alternatives.

Part Context

The 9ERS3165BGILFT is part of the 9ERS3165B family from Renesas Electronics. It is functionally equivalent to the ICS9ERS3165BGILF variant. The 'T' suffix typically denotes tape and reel packaging, distinguishing it from tube-packaged versions like the 9ERS3165BGILF.

Replacement Considerations

As the 9ERS3165BGILFT is discontinued, direct replacement requires evaluating new clock synthesizers from Renesas or other manufacturers that offer CK505 compatibility, similar output counts, and industrial temperature ratings. Pin-to-pin substitutes are not explicitly confirmed in public documentation.
