8T49N105A-008NLGI8

Overview

The IDT8T49N105I is a FemtoClock NG Universal Frequency Translator and Synthesizer featuring low phase noise and alarm monitoring functions. It generates output frequencies from 0.98MHz to 312.5MHz, with most frequencies supported up to 1,300MHz. The device supports three operating modes: Frequency Synthesizer using fractional feedback division, High-Bandwidth Frequency Translator for tracking input changes like Spread-Spectrum Clock modulation, and Low-Bandwidth Frequency Translator for jitter attenuation. It accepts differential inputs (LVPECL, LVDS, LVHSTL, HCSL) in the 8kHz-710MHz range or crystals from 16MHz-40MHz. Outputs are programmable as LVPECL or LVDS.

Feature Summary

Single differential output pair (Q, nQ) configurable as LVPECL or LVDS
Three operating modes: Frequency Synthesizer, High-Bandwidth Translator, Low-Bandwidth Translator
Two factory-programmed default configurations stored in OTP memory
Alarm outputs for HOLDOVER, CLK_BAD, XTAL_BAD, and LOCK_IND status

Applications

Networking and communications applications requiring jitter attenuation
PCI Express, computing, and general-purpose frequency translation
Line cards supporting multiple I/O modules with different clock requirements

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and lead-free status. Confirm that the 'A' revision designation aligns with the required datasheet version for design-in purposes.

Selection Notes

Select this component when a single output channel is sufficient for the application. Ensure the required output frequency falls within the supported divider ranges defined in Table 3 of the datasheet. Verify that the input reference frequency matches one of the supported modes (crystal or differential clock).

Part Context

This device belongs to the FemtoClock NG family of Universal Frequency Translators. It utilizes fourth-generation PLL technology to provide flexible frequency synthesis and translation capabilities with low phase noise performance suitable for high-speed digital interfaces.

Replacement Considerations

Consult Renesas Electronics for direct replacements or updated revisions. Verify pin compatibility and register settings if substituting with other models in the 8T49N series.
