8T49N203A-001NLG

Overview

The Renesas Electronics Corporation 8T49N203A-001NLG is a FemtoClock NG Universal Frequency Translator and Synthesizer. It generates output frequencies from 0.98MHz to 1,300MHz using two differential inputs (LVPECL, LVDS, LVHSTL, HCSL) or a crystal input (16MHz - 40MHz). The device features two individually programmable LVPECL or LVDS outputs with supply voltages of 2.5V or 3.3V. It supports three operating modes: Frequency Synthesizer, High-Bandwidth Frequency Translator, and Low-Bandwidth Frequency Translator. Key electrical parameters include an input frequency range of 8kHz - 710MHz, RMS phase jitter of 439fs at 155.52MHz (Low Bandwidth Mode), and 285fs at 400MHz (Synthesizer Mode). It operates within a temperature range of -40°C to 85°C in a 40-VFQFN package.

Feature Summary

Fourth-generation FemtoClock NG technology for low phase noise performance
Two factory-programmable default configurations stored in One-Time Programmable (OTP) memory
I2C serial interface for register programming and post-power-up configuration overwriting
Supports manual and automatic clock switching with hitless transition capabilities

Applications

Networking and communications line cards
PCI Express and computing applications
General purpose clock translation

Procurement Notes

Verify the specific ordering suffix '001' against official documentation to confirm the programmed OTP configuration details. Confirm current manufacturing status as this component family has undergone discontinuation notices. Ensure compatibility with required I2C address settings via S_A0 and S_A1 pins.

Selection Notes

Select this device when zero ppm frequency translation is required between disparate input and output frequencies. Choose the Low-Bandwidth mode for significant jitter attenuation using an external crystal, or High-Bandwidth mode to track spread-spectrum modulation. Verify that the desired output frequency falls within the supported divider ranges defined in the datasheet tables.

Part Context

This component belongs to the IDT8T49N203I FemtoClock NG Universal Frequency Translator series. It is designed as a general-purpose clock generator suitable for applications requiring flexible frequency synthesis and translation. The device integrates alarm and monitoring functions to ensure signal integrity in critical networking environments.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Consult manufacturer documentation for updated product offerings if this component is discontinued.
