843021AGI-01LF

Overview

The 843021AGI-01LF is a clock synthesizer and jitter cleaner manufactured by Renesas Electronics Corporation. It belongs to the FemtoClock series and features one input and two outputs with LVPECL output levels. The device supports a maximum output frequency of 170 MHz and accepts LVCMOS or LVTTL input levels, with a maximum input frequency of 27.2 MHz. It operates on a supply voltage ranging from 2.375 V to 3.63 V and draws 13 mA of working current. Packaged in a TSSOP-20 format for surface mount installation, it functions within an ambient temperature range of -40°C to +85°C. This component is currently listed as obsolete.

Feature Summary

• Dual LVPECL outputs for high-speed clock distribution
• Integrated jitter cleaning capabilities
• Compatible with LVCMOS/LVTTL inputs
• Low power consumption of 13 mA

Applications

• High-performance computing systems requiring low-jitter clocks
• Telecommunications infrastructure equipment
• Data acquisition systems

Procurement Notes

This component is officially marked as obsolete by the manufacturer. Availability is restricted to surplus distributors or last-time-buy channels. Verify RoHS compliance status through official datasheets before procurement. Supply chain stability cannot be guaranteed due to end-of-life status.

Selection Notes

Select this part only if dual LVPECL outputs are required with LVCMOS/LVTTL input compatibility. Ensure the design accommodates the 24-TSSOP package dimensions. Consider alternative active components from the same FemtoClock family if long-term supply continuity is critical for the product lifecycle.

Part Context

Part of the Renesas FemtoClock series designed for precision timing applications. The 843021 variant specifically provides a 1:2 ratio configuration. It serves as a successor to earlier IDT clock synthesizers following the Renesas acquisition of Integrated Circuit Systems (ICS).

Replacement Considerations

Direct pin-to-pin replacements may not exist due to obsolescence. Evaluate other FemtoClock devices with similar I/O configurations. Consult Renesas technical support for validated cross-reference options compatible with LVPECL outputs.
