8T49N366A-000ASGI

Overview

The Renesas 8T49N366A-000ASGI is a Universal Frequency Translator (UFT) featuring three fully independent Phase-Locked Loops (PLLs). It supports input frequencies from 8 kHz to 710 MHz and generates programmable outputs ranging from 0.98 MHz to 1,300 MHz. The device offers LVPECL or LVDS output signaling types with a typical RMS phase jitter of 465 fs in Low Bandwidth mode and 333 fs in Synthesizer mode. Operating on a full 2.5 V ±5% supply, it functions within an ambient temperature range of -40 °C to +85 °C and is housed in a 10 mm x 10 mm lead-free CABGA package.

Feature Summary

• Integrates three fully independent PLLs for flexible frequency synthesis and translation.
• Supports wide input frequency range from 8 kHz to 710 MHz with multiple input types including LVPECL, LVDS, LVHSTL, and HCSL.
• Provides low-phase noise performance with typical RMS jitter of 465 fs (Low Bandwidth) and 333 fs (Synthesizer mode).
• Features I²C serial interface for register programming and includes alarm/monitoring functions.

Applications

• Networking equipment requiring precise clock distribution.
• Communications systems utilizing frequency translation and jitter attenuation.
• Base station infrastructure needing multiple independent clock domains.

Procurement Notes

Verify the specific suffix '000ASGI' against official Renesas documentation to confirm pinout, packaging dimensions, and electrical characteristics match the standard 8T49N366I family specifications. Confirm current production status and availability through authorized distributors, as clock generator models frequently undergo lifecycle changes.

Selection Notes

Select this component when three independent clock sources are required within a single package. Ensure the design accommodates the 2.5 V supply voltage and utilizes LVPECL or LVDS termination networks. Verify that the required output frequencies fall within the 0.98 MHz to 1,300 MHz range supported by the device's fractional-N and integer-N PLL modes.

Part Context

The 8T49N366A belongs to the FemtoClock NG Universal Frequency Translator family. Related devices include the dual PLL 8T49N244I and quad PLL variants such as the 8T49N445I and 8T49N488I, which offer different output counts while sharing similar low-jitter architecture and interface capabilities.

Replacement Considerations

Direct replacements within the same family include the 8T49N366I. For applications requiring fewer outputs, the 8T49N244I may be suitable. For higher channel counts, consider the 8T49N445I or 8T49N488I. Verify pin compatibility and software configuration tools before substitution.
