8T49N004A-048NLGI

Overview

The 8T49N004A-048NLGI is a clock generator from the FemtoClock NG series manufactured by Renesas Electronics Corporation. It features one circuit with a maximum frequency of 300MHz and a 1:4 input-to-output ratio. The device accepts HCSL, LVDS, or LVPECL inputs and provides four differential LVPECL outputs. Powered by a 2.375V to 3.465V supply, it operates within a -40°C to 85°C temperature range. The component is housed in a 32-VFQFN package with an exposed pad and includes a PLL with bypass functionality.

Feature Summary

• Generates up to four independent LVPECL output clocks from a single input source
• Supports HCSL, LVDS, and LVPECL input formats for flexible integration
• Operates on a single 2.5V or 3.3V power supply (2.375V ~ 3.465V)
• Available in a compact 32-VFQFN (5x5 mm) surface-mount package

Applications

• High-speed data communication equipment requiring low-jitter clocking
• Network infrastructure line cards and switches
• Test and measurement instrumentation
• Broadcast video systems

Procurement Notes

This specific part number is listed as obsolete or discontinued by major distributors. Verification of current stock availability and end-of-life status is required before procurement planning. Alternative components within the same FemtoClock NG family should be evaluated for pin-compatible replacements if long-term supply is necessary.

Selection Notes

Select this component when four differential LVPECL outputs are required at frequencies up to 300MHz. Ensure the system design supports the specified 2.375V to 3.465V supply voltage. Verify that the input signal format matches the supported HCSL, LVDS, or LVPECL standards. The 32-VFQFN package requires appropriate thermal management considerations due to the exposed pad design.

Part Context

The 8T49N004A belongs to the FemtoClock NG family, designed for jitter attenuation and frequency synthesis. This series is characterized by low phase noise and programmable output frequencies. The '048' suffix typically denotes a specific factory configuration or programming code, while 'NLGI8' indicates the tape-and-reel packaging variant.
