309RILF

Overview

The Renesas Electronics Corporation 309RILF is a clock/frequency synthesizer IC belonging to the VersaClock series. It operates with a maximum frequency of 200MHz and features a 1:9 input-to-output ratio. The device supports LVCMOS outputs and accepts clock or crystal inputs. It functions within a supply voltage range of 3V to 3.6V and is designed for surface mount installation in a 20-SSOP package (0.154 inch width). The component includes a PLL with bypass capability and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• VersaClock series clock/frequency synthesizer with 200MHz maximum frequency
• 1:9 input to output ratio with LVCMOS output types
• Operates on 3V to 3.6V supply voltage
• Available in 20-SSOP surface mount package

Applications

• General clock distribution systems
• Frequency synthesis for digital circuits
• Embedded system timing applications

Procurement Notes

Verify the exact part number suffix, as public records indicate '309RLF' rather than '309RILF'. Confirm availability status, as related variants are marked as obsolete or end-of-life. Check moisture sensitivity level (MSL 1) and handling requirements before procurement. Ensure the supplier provides official documentation matching the specific suffix configuration.

Selection Notes

Select this component when a 200MHz frequency synthesizer with nine outputs is required. Ensure the design accommodates the 3V to 3.6V power supply constraint. Verify that LVCMOS output levels meet the receiving logic requirements. Consider the 20-SSOP footprint constraints during PCB layout. Confirm compatibility with the 0°C to 70°C commercial temperature range.

Part Context

The 309RILF belongs to the Renesas VersaClock family, which specializes in clock generation and distribution solutions. This series typically integrates PLL technology for stable frequency synthesis. The base product number is 309R. Variants may differ by packaging or temperature rating. The device serves as a central timing element in systems requiring multiple synchronized clock signals derived from a single reference.

Replacement Considerations

Public data indicates the 309RLF variant is obsolete. No direct public substitute part numbers are confirmed for this specific model. Designers should consult Renesas for current alternatives within the VersaClock portfolio. Verify pinout and electrical parameter compatibility if considering cross-brand replacements.
