8T49N244A-002ASGI

Overview

The 8T49N244A-002ASGI is a dual-PLL FemtoClock NG Universal Frequency Translator manufactured by Renesas Electronics. It operates within a -40°C to +85°C temperature range and utilizes an 80-pin CABGA package. The device supports LVDS output signaling with a maximum frequency of 1.3 GHz. Key electrical parameters include a maximum input frequency of 710 MHz, a typical phase jitter of 40 ps, and a supply voltage range of 2.5 V or 3.3 V. The specific ordering suffix -002 configures the device for Low Bandwidth (LoBW) mode with manual pin-based switchover.

Feature Summary

• Dual-PLL architecture supporting independent frequency synthesis
• Low Bandwidth (LoBW) operation with manual pin control
• LVDS differential output signaling
• Maximum output frequency up to 1.3 GHz

Applications

• Networking equipment clock distribution
• Telecommunications infrastructure timing
• High-speed data converter synchronization

Procurement Notes

Verify the exact configuration requirements against the FemtoClock UFT Order Guide before procurement. Confirm that the manual pin switchover method aligns with the system design constraints. Ensure compatibility with the specified 80-CABGA package dimensions and soldering profiles during assembly planning.

Selection Notes

Select this component when a dual-PLL solution with low bandwidth jitter attenuation is required. The -002 suffix specifically dictates the internal register settings for input/output frequencies and power-up states. Verify that the system can accommodate the manual pin configuration logic rather than I2C programming if dynamic changes are needed.

Part Context

This part belongs to the 8T49N244I family of Universal Frequency Translators. It is designed to replace legacy clock generators in high-performance applications requiring precise timing and low phase noise. The device integrates jitter cleaning and frequency translation capabilities into a single compact package.
