8T49N203A-012NLGI8

Overview

The 8T49N203A-012NLGI8 is a Universal Frequency Translator from the FemtoClock NG series, manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2.375V to 3.465V and supports input levels including HCSL, LVDS, LVHSTL, LVPECL, and crystals. The device features a 3:2 input-to-output ratio with differential inputs and outputs. It is housed in a 40-VFQFN package with an exposed pad and functions as a clock generator or PLL frequency synthesizer. The maximum frequency is 25MHz, and it includes a PLL with bypass capability.

Feature Summary

• Universal frequency translation with 3:2 input-to-output ratio
• Supports multiple input formats: HCSL, LVDS, LVHSTL, LVPECL, and crystal
• Differential LVPECL output configuration
• Operates on 2.375V to 3.465V supply voltage

Part Context

This component belongs to the FemtoClock NG family of universal frequency translators. These devices are designed for applications requiring precise clock generation and jitter attenuation. The specific model integrates fractional-feedback PLL technology to translate various input frequencies into stable output clocks suitable for high-speed digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers include 8T49N241-994NLGI, 8T49N241-998NLGI, and 8T49N241-999NLGI. Verification of electrical compatibility and pinout alignment is required before substitution.
