9ERS3165BKILF

Overview

The 9ERS3165BKILF is a clock synthesizer and jitter cleaner manufactured by Renesas Electronics. It serves as an embedded CK505-compatible clock solution designed for industrial temperature applications. The device integrates a voltage regulator, eliminating the need for external pass transistors. It features differential push-pull outputs with integrated 33-ohm series resistors, providing a characteristic impedance of 50 ohms. The component supports spread spectrum modulation with a default 0.5% down-spread capability to reduce electromagnetic interference.

Feature Summary

• CK505 compatible clock synthesizer for embedded systems
• Integrated 33-ohm series resistors on differential outputs (Zo=50Ω)
• Supports spread spectrum modulation (default 0.5% down spread)
• Single-ended programmable slew rate control for RFI reduction

Applications

• Industrial embedded systems requiring CK505 compatibility
• PCI bus clock generation (33MHz)
• USB clock generation (48MHz)
• CPU and SRC differential clock distribution

Procurement Notes

The 9ERS3165BKILF is listed as an End-of-Life (EOL) product by Renesas Electronics. Availability is restricted, and distributors may report limited stock or discontinuation notices. Verification of current supply status and alternative sourcing strategies is required before procurement planning.

Selection Notes

This component requires an external 14.318 MHz crystal and corresponding load capacitors for frequency tuning. Designers must account for the specific output configuration options, which include selectable SRC differential pairs and single-ended outputs. Ensure the application environment falls within the specified operating temperature range for this variant.

Part Context

The 9ERS3165B belongs to Renesas' family of clock synthesizers and jitter cleaners. This specific part number denotes the industrial temperature grade version of the 9ERS3165B series. It is categorized under Clock & Timer ICs, specifically functioning as a clock generator supporting multiple interface standards including PCI and USB.

Replacement Considerations

As the 9ERS3165BKILF is discontinued, engineers should consult Renesas documentation for direct replacements or pin-compatible alternatives within the same CK505-compatible portfolio. Verify that any substitute maintains the required output configurations and electrical specifications.
