831752AGILFT

Overview

The 831752AGILFT is a high-performance, differential HCSL clock switch manufactured by Renesas Electronics. Designed for ATCA/AMC and PCIe applications, it supports Gen 1 (2.5 Gb/s), Gen 2 (5 Gb/s), and Gen 3 (8 Gb/s) data rates with a maximum frequency of 500 MHz. The device features one bi-directional differential I/O (FCLK) and one local differential clock input (CLK). It operates on a full 3.3V or 2.5V supply voltage and provides an HCSL output (Q). The component is housed in a lead-free 16-lead TSSOP package and is characterized for operation between -40°C and +85°C.

Feature Summary

• Supports PCI Express Gen 1, Gen 2, and Gen 3 jitter compliance
• Bi-directional FCLK I/O accepts HCSL, LVDS, and LVPECL levels
• Local CLK input accepts HCSL, LVDS, and LVPECL differential signals
• Operates on 3.3V or 2.5V power supplies

Applications

• ATCA (Advanced Telecom Computing Architecture) systems
• AMC (Advanced Mezzanine Card) systems
• PCIe clock routing and distribution

Procurement Notes

Verify the specific suffix 'GILFT' against the manufacturer's official datasheet to confirm RoHS compliance and tape-and-reel packaging details. Ensure the ordering quantity aligns with the manufacturer's standard carrier type requirements. Cross-reference the part number with authorized distributors to confirm current availability status and lead times.

Selection Notes

Select this component when designing for ATCA or AMC backplanes requiring flexible clock source switching. It is suitable for environments needing support for multiple clock input standards (HCSL, LVDS, LVPECL). Verify that the system requires a single-channel switch with bi-directional capability rather than a fixed buffer or multiplexer configuration.

Part Context

This part belongs to the Renesas 8317 series of clock switches. These devices are engineered specifically for high-speed serial interface timing solutions. The 831752I variant serves as the base model for this family, optimized for low skew and jitter performance in demanding telecommunications and computing infrastructure applications.
