8T49N1012-005NLGI8

Overview

The 8T49N1012-005NLGI8 is a clock generator integrated circuit manufactured by Renesas Electronics Corporation, belonging to the FemtoClock NG series. It features a single PLL configuration with a maximum output frequency of 300MHz. The device accepts differential inputs in HCSL, LVDS, or LVPECL formats and provides four LVPECL outputs, resulting in a 1:4 input-to-output ratio. It operates on a supply voltage ranging from 2.375V to 3.465V and functions within an ambient temperature range of -40°C to 85°C. The component is housed in a 32-VFQFN package with an exposed pad.

Feature Summary

• Single PLL architecture supporting up to 300MHz output frequency
• Differential input compatibility with HCSL, LVDS, and LVPECL standards
• Four LVPECL output channels for signal distribution
• Operates within a 2.375V to 3.465V power supply range

Applications

• High-speed digital system clock generation
• Data communication equipment timing
• Industrial control systems requiring low jitter clocks

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on distributor surplus stock or secondary market sources rather than direct manufacturing orders. Confirm RoHS3 compliance and MSL level 3 handling requirements during acquisition.

Selection Notes

Designers requiring this specific 1:4 LVPECL configuration must account for the component's end-of-life status. Alternative selection should prioritize devices within the same FemtoClock NG family that offer similar input/output ratios and voltage specifications while ensuring current production availability.

Part Context

The 8T49N1012-005NLGI8 is part of the broader 8T49N004 family, specifically identified by the ordering suffix indicating its pinout and electrical characteristics. It serves as a specialized clock translator within Renesas' portfolio for applications demanding precise frequency synthesis from various input standards.

Replacement Considerations

Direct functional substitutes are not explicitly confirmed in public documentation for this exact obsolete part number. Engineers should evaluate other 8T49N004 variants or newer FemtoClock NG generations with compatible I/O levels and packaging.
