8T49N287A-999NLGI#

Overview

The 8T49N287A-999NLGI# is a FemtoClock NG Universal Frequency Translator manufactured by Renesas Electronics. It operates within a supply voltage range of 2.375V to 3.465V and supports an operating temperature range of -40°C to 85°C. The device utilizes a 72-VFQFN exposed pad package with dimensions of 10x10 mm. It features a maximum frequency of 1GHz, supporting input formats including HCSL, LVCMOS, LVDSM, LVHSTL, LVPECL, and crystals. Output options include HSCL, LVCMOS, LVDS, and LVPECL. The component has a 5:8 input-to-output ratio and includes divider/multiplier capabilities.

Feature Summary

• Universal Frequency Translator architecture with 5:8 input-to-output ratio
• Maximum output frequency of 1GHz with multiple input/output format support
• Integrated PLL with bypass capability for flexible clock management
• RoHS3 compliant with MSL level 3 (168 hours) moisture sensitivity rating

Applications

• High-speed data communication systems requiring precise clock translation
• Telecommunications infrastructure utilizing GR.1244 Stratum standards
• Server and storage backplane clock generation
• Networking equipment requiring low-jitter clock synthesis

Procurement Notes

Verify the specific ordering suffix 'NLGI#' against official Renesas documentation to confirm package type and tape/reel specifications. Confirm current lifecycle status as distribution channels may list varying availability or end-of-life notifications. Ensure compatibility with existing board designs regarding the 72-VFQFN footprint and thermal requirements.

Selection Notes

Select this component when a 1GHz universal frequency translator with 5:8 ratio is required. Verify that the 2.375V to 3.465V supply voltage aligns with system power rails. Consider the 72-VFQFN package size for PCB layout constraints. Check if the supported input/output logic families (LVPECL, LVDS, etc.) match the source and destination devices in the design.

Part Context

This part belongs to the FemtoClock NG family of Universal Frequency Translators from Renesas. It is related to other models such as the 8T49N286A and 8T49N287 series, which offer similar functionality with varying pin counts and ratios. The 'A' suffix typically denotes a specific revision or variant within the 8T49N287 product line.

Replacement Considerations

Direct substitutes may include other 8T49N287 variants with compatible ratios and frequencies. Verify pin-to-pin compatibility and electrical parameters before substitution. Consult Renesas documentation for recommended alternatives if this specific suffix is discontinued.
