843021AGLF

Overview

The Renesas Electronics Corporation 843021AGLF is a FemtoClock crystal clock generator featuring LVPECL outputs. It operates within a supply voltage range of 3.135V to 3.465V and is housed in an 8-TSSOP package. The device supports input frequencies up to 27.2 MHz and generates output frequencies up to 170 MHz. Designed for surface-mount installation, it functions reliably across an operating temperature range of -40°C to +85°C. This component is classified under Clock Generators and is part of the 843021 series.

Feature Summary

• FemtoClock crystal-based clock generation with LVPECL output levels
• Operates on a single 3.3V power supply (3.135V to 3.465V)
• Compact 8-TSSOP surface-mount package

Applications

• High-speed digital signal processing systems requiring low jitter clocks
• Telecommunications equipment utilizing LVPECL interfaces
• Data acquisition systems needing precise timing synchronization

Procurement Notes

The 843021AGLF is officially listed as End-of-Life (EOL) by Renesas Electronics. Availability is restricted, and distributors may not stock this item in all regions. Verification of current lifecycle status and alternative sourcing channels is required before procurement planning.

Selection Notes

Select this component when LVPECL outputs and FemtoClock jitter attenuation are required in an 8-pin form factor. Ensure the design accommodates the 3.3V supply constraint and the -40°C to +85°C industrial temperature range. Verify that the input frequency requirements align with the specified maximums.

Part Context

This part belongs to the Renesas FemtoClock family, specialized for clock synthesis and jitter cleaning. It shares the 843021 series designation but differs from variants like the 843021AGILF in specific suffix configurations. It serves as a timing solution for high-performance digital applications requiring stable clock distribution.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineering evaluation of compatible FemtoClock alternatives or pin-compatible upgrades from the manufacturer's current portfolio is necessary.
