308RILFT

Overview

The Renesas 308RILFT is a VersaClock clock/frequency synthesizer IC designed for generating precise timing signals. It operates with a single circuit and supports a maximum frequency of 200MHz. The device accepts clock or crystal inputs and provides LVCMOS outputs. It functions within a supply voltage range of 3V to 3.6V and is rated for an operating temperature between -40°C and 85°C. The component is housed in a 20-SSOP package with a width of 3.90mm, suitable for surface mount applications.

Feature Summary

• Integrated PLL with bypass capability
• 1:9 input-to-output ratio configuration
• LVCMOS output logic levels
• Industrial temperature range operation (-40°C to 85°C)

Applications

• General-purpose clock generation in embedded systems
• Frequency synthesis for digital circuits requiring 200MHz stability
• Timing reference distribution in consumer electronics

Procurement Notes

The 308RILFT is officially listed as obsolete by the manufacturer. Product Change Notices indicate end-of-life status effective April 26, 2018. Availability is limited to existing stock or surplus channels. Verification of authenticity and storage history is critical due to the discontinued status. Designers should initiate replacement strategies immediately.

Selection Notes

This component is specific to the VersaClock family and requires a 3V to 3.6V power supply. It lacks differential input/output options, utilizing single-ended LVCMOS outputs. Engineers must ensure the application does not require higher frequencies than 200MHz or different output drive strengths. The 20-SSOP footprint dictates PCB layout constraints.

Part Context

The 308RILFT belongs to the Renesas VersaClock series, formerly associated with IDT clock products. It serves as a fixed-function or programmable (depending on specific variant suffixes not detailed here) synthesizer. The part number suffix 'ILFT' denotes the industrial temperature grade and tape-and-reel packaging format.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-compatible replacements from other manufacturers or newer Renesas families must be evaluated based on specific electrical requirements.
