854S204BGILFT

Overview

The Renesas 854S204BGILFT is a high-performance dual 1:4 LVDS fanout buffer designed for clock distribution in space-constrained applications. It features two independent buffers, each providing four low-skew outputs from differential inputs that accept LVDS and LVPECL levels. The device operates on a single 2.5V supply with a maximum input frequency of 2GHz. Key electrical characteristics include a maximum output-to-output bank skew of 35ps and a propagation delay of 300ps. It is housed in a 28-lead VFQFPN package (5.0 x 5.0 mm) and supports an ambient operating temperature range of -40°C to 85°C.

Feature Summary

• Dual 1:4 LVDS fanout buffers with integrated bias voltage generators for single-ended signal interfacing
• Maximum input clock frequency of 2GHz with low additive RMS phase jitter of 105fs (156.25MHz)
• Guaranteed output-to-output skew of 35ps (maximum) and part-to-part skew of 350ps (maximum)
• Operates on a single 2.5V supply in a compact 28-lead VFQFPN package

Applications

• High-frequency clock distribution for networking equipment
• Data communication systems requiring low additive phase noise
• Space-constrained boards needing precise timing repeaters

Procurement Notes

Verify the specific suffix 'GILFT' corresponds to the lead-free (RoHS 6) tape and reel packaging configuration. Confirm the manufacturer source directly with Renesas or authorized distributors to ensure authenticity, as component availability may vary by region.

Selection Notes

Select this component when a dual-channel LVDS fanout solution is required with strict skew constraints under 35ps. Ensure the system design utilizes a 2.5V power supply and accommodates the 28-lead VFQFPN footprint. Verify that the input signal levels are compatible with LVDS or LVPECL standards.

Part Context

This component belongs to the IDT (Integrated Device Technology) clock buffer family, now part of Renesas Electronics. It serves as a specialized timing solution for high-speed digital interfaces, distinct from general-purpose logic buffers by its focus on minimizing jitter and skew in differential signaling environments.

Replacement Considerations

Direct functional replacements within the same family include the 8SLVD2104. Verify pin compatibility and electrical specifications against the original design requirements before substitution.
