831742AGILF

Overview

The Renesas 831742AGILF is a high-performance differential HCSL clock and data multiplexer with fanout buffer capabilities. It features four selectable differential input pairs capable of accepting HCSL, LVDS, LVPECL, and SSTL signal levels. The device distributes the selected input to two low-skew differential HCSL output pairs. Characterized for operation from a single 3.3V supply, it supports maximum input/output clock frequencies of 700MHz and data rates up to 1400Mb/s (NRZ). Key electrical specifications include a maximum input skew of 110ps and part-to-part skew of 225ps.

Feature Summary

• Four selectable differential input pairs supporting HCSL, LVDS, LVPECL, and SSTL levels
• Two differential HCSL output pairs with low skew characteristics
• Maximum input/output clock frequency of 700MHz and data rate of 1400Mb/s (NRZ)
• Input skew max 110ps; Part-to-part skew max 225ps

Applications

• PCI Express (2.5Gb/s) clock multiplexing and distribution
• PCI Express Gen 2 (5Gb/s) clock multiplexing and distribution
• High-frequency clock and data signal distribution systems

Procurement Notes

Verify current production status as the related 831721AGILF model is discontinued. Confirm RoHS compliance details via official datasheets before procurement. Ensure compatibility with 3.3V supply requirements and TSSOP-16 package constraints during sourcing.

Selection Notes

Select this component when designing systems requiring multiplexing of multiple differential clock sources into a single low-skew output. Verify that input signals match supported voltage levels (HCSL, LVDS, LVPECL, SSTL). Ensure system timing budgets accommodate the specified 110ps input skew and 225ps part-to-part skew limits.

Part Context

The 831742I series belongs to Renesas' clock driver and distribution product line. This specific variant focuses on differential signal handling for high-speed serial interfaces. It serves as a critical interconnect component in complex digital systems requiring precise clock routing and source selection.

Replacement Considerations

Check for direct pin-compatible substitutes within the same ICS/Renesas portfolio. Verify if alternative multiplexers meet the 700MHz frequency and 1400Mb/s data rate requirements without compromising skew specifications.
