831742AGILFT

Overview

The 831742AGILFT is a high-performance, differential HCSL clock/data multiplexer and fanout buffer manufactured by Renesas Electronics Corporation. 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 with a full 3.3V supply voltage, it supports maximum input/output clock frequencies of 700MHz and data rates up to 1400Mb/s (NRZ). All control inputs utilize LVCMOS interface levels.

Feature Summary

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

Applications

• PCI Express (2.5Gb/s) and Gen 2 (5 Gb/s) clock jitter compliant distribution
• High-frequency clock and data signal multiplexing
• Clock and data distribution in applications requiring well-defined performance and repeatability

Procurement Notes

Verify the specific suffix 'GILFT' against official Renesas documentation to confirm lead-free status and tape-and-reel packaging details. Confirm current production status and availability through authorized distributors, as component lifecycle stages may change. Ensure compatibility with 3.3V supply requirements and LVCMOS control logic levels during sourcing.

Selection Notes

Select this component when a differential HCSL multiplexer with four selectable inputs and two outputs is required. Verify that the application demands support for mixed input standards including LVDS, LVPECL, and SSTL alongside HCSL. Ensure the system operates within the specified -40°C to 85°C ambient temperature range and utilizes a 3.3V power supply.
