871S1022EKLFT

Overview

The 871S1022EKLFT is a clock synthesizer and jitter cleaner from the Renesas 871S1022 series, designed for multi-rate femtoclock applications. It features four outputs with HCSL output levels and supports input levels including HCSL, LVDS, and LVHSTL. The device operates within a supply voltage range of 3.135 V to 3.465 V and handles maximum input frequencies up to 100 MHz while delivering maximum output frequencies of 500 MHz. Packaged in a VFQFPN-32 format, it functions within an operating temperature range of 0°C to +70°C and draws approximately 100 mA during operation.

Feature Summary

• Four-output configuration supporting HCSL output levels
• Multi-rate femtoclock capability for jitter cleaning
• Flexible input compatibility with HCSL, LVDS, and LVHSTL signals
• VFQFPN-32 surface-mount package design

Applications

• PCI Express system clock generation
• High-speed digital interface synchronization
• Jitter attenuation in data communication links

Procurement Notes

This component is identified as obsolete or end-of-life by the manufacturer. Verification of availability should focus on surplus distributors or last-time-buy status rather than standard production channels. Confirm RoHS compliance details directly with current stock holders as specifications may vary across legacy batches.

Selection Notes

Designers requiring this specific part number must account for its discontinued status. When evaluating alternatives, ensure replacement components match the 3.135 V to 3.465 V supply range, 500 MHz maximum output frequency, and VFQFPN-32 package dimensions. Verify that substitute devices support the required HCSL output and LVDS/LVHSTL input combinations for direct pin-to-pin compatibility.

Part Context

The 871S1022EKLFT belongs to the Renesas 871S1022 family of clock synthesizers. This series is specifically engineered for high-performance timing applications requiring low jitter performance. The 'T' suffix typically denotes tape-and-reel packaging, distinguishing it from tray-packaged variants like the 871S1022EKLF.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation due to the component's obsolete status. Engineers should consult Renesas migration guides for modern femtoclock alternatives that maintain similar electrical characteristics and package footprints.
