8T49N203A-001NLG8

Overview

The Renesas Electronics Corporation 8T49N203A-001NLG8 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 source (16MHz - 40MHz). The device features two individually programmable LVPECL or LVDS outputs with 2.5V or 3.3V levels. It supports three operating modes: frequency synthesizer, high-bandwidth translator, and low-bandwidth translator. Power supply ranges from 2.375V to 3.465V. It operates within an ambient temperature range of -40°C to 85°C in a 40-VFQFN package.

Feature Summary

Universal Frequency Translator / Synthesizer supporting 0.98MHz to 1,300MHz output
Two differential inputs accepting LVPECL, LVDS, LVHSTL, HCSL, or crystal sources
Two individually programmable LVPECL or LVDS outputs with 2.5V/3.3V support
Three operating modes: Frequency Synthesizer, High-Bandwidth Translator, Low-Bandwidth Translator

Applications

Networking and communications applications
PCI Express systems
Computing infrastructure

Procurement Notes

Verify the specific ordering suffix for factory-programmed configurations. The device contains OTP memory for two default power-up states selected by the CONFIG pin. Confirm that the required input/output frequency translation ratios and PLL loop bandwidths match the pre-programmed settings or plan for I2C reconfiguration after power-up.

Selection Notes

Select this component when flexible frequency translation between disparate input and output rates is required. Ensure the desired output frequency falls within the supported divider ranges defined in Table 3. Verify that the input clock types (LVPECL, LVDS, etc.) are compatible with the CLK_SEL configuration. Check if the jitter attenuation requirements align with the low-bandwidth mode capabilities.

Part Context

This part belongs to the IDT8T49N203I FemtoClock NG family. It is designed as a general-purpose clock generator suitable for replacing multiple fixed-frequency oscillators. The device integrates alarm monitoring functions such as LOCK_IND, HOLDOVER, and BAD inputs for system reliability.
