8737AG-11LF

Overview

The Renesas Electronics 8737AG-11LF is a clock generator and support product, specifically functioning as a 1:4 LVPECL fanout buffer. It belongs to the 8737I-11 series and is manufactured in a TSSOP-20 surface-mount package. The component is classified under Clock & Timer ICs. According to available distributor records, this specific part number has reached end-of-life status. It is designed for applications requiring differential LVPECL output buffering.

Feature Summary

• Function: 1:4 LVPECL Fanout Buffer
• Package: TSSOP-20 (SMD/SMT)
• Series: 8737I-11
• Status: End of Life / Discontinued

Applications

• Clock distribution systems requiring LVPECL signaling
• High-speed digital circuit buffering
• Telecommunications equipment clocking

Procurement Notes

This component is officially discontinued by Renesas Electronics. Availability is restricted to remaining stock from third-party distributors or surplus markets. Verification of authenticity and storage history is critical due to the EOL status. No new production units are expected from the manufacturer.

Selection Notes

Designers should consider pin-compatible or functionally equivalent replacement components from current Renesas portfolios or other manufacturers. Since the 8737AG-11LF is obsolete, long-term supply chain stability cannot be guaranteed with this part number. Evaluate alternative LVPECL fanout buffers with active manufacturing status.

Part Context

The 8737AG-11LF is part of the broader 8737I-11 family of clock buffers. It serves as a differential-to-differential buffer converting one input to four LVPECL outputs. Similar parts in the lineup include variants with different output configurations or voltage levels within the same TSSOP-20 footprint.
