854S712AKILFT

Overview

The Renesas 854S712AKILFT is a differential, high-speed 1:2 data and clock fanout buffer with an integrated line driver. Designed for applications requiring up to 4.5 Gbps NRZ data rates, it features configurable pre-emphasis to optimize signal integrity on backplanes and long transmission lines by reducing inter-symbol interference. The device accepts LVDS, LVPECL, or CML inputs and provides two LVDS-compliant outputs. It operates from a single 3.3V supply within the industrial temperature range of -40°C to +85°C and is housed in a compact VFQFN-16 package.

Feature Summary

• Configurable pre-emphasis output stage for optimizing low bit error rate or power consumption
• Supports data rates up to 4.5 Gbps (NRZ) with optimized deterministic jitter performance
• Internal input termination and bias voltage output for AC-coupling support
• LVDS-compliant outputs compatible with LVDS, LVPECL, and CML input signals

Applications

• High-speed data communication systems requiring fanout buffering
• Backplane and long transmission line driving applications
• Clock distribution networks needing low additive jitter
• Data applications requiring minimized inter-symbol interference

Procurement Notes

Verify the specific suffix 'AKILFT' against the manufacturer's current datasheet to confirm pinout, packaging dimensions, and RoHS compliance status. Confirm moisture sensitivity level handling requirements prior to assembly. Check for any product change notifications that may affect lead time or material composition.

Selection Notes

Select this component when a differential 1:2 fanout buffer with adjustable pre-emphasis is required for 4.5 Gbps signals. Ensure the design supports a 3.3V supply and utilizes the VFQFN-16 footprint. Verify that the input source matches the supported LVDS, LVPECL, or CML levels and that the internal termination meets the impedance requirements.

Part Context

This part belongs to the 854S712I series of high-speed clock buffers and drivers. It is distinct from other Renesas clock products by its specific combination of 1:2 fanout topology and configurable pre-emphasis capabilities, targeting high-speed serial data recovery and distribution rather than simple clock splitting.

Replacement Considerations

Direct substitutes must match the 1:2 differential fanout configuration, 4.5 Gbps speed, and VFQFN-16 package. Verify electrical compatibility regarding input/output voltage levels and pre-emphasis functionality before swapping.
