8T49N105A-006NLGI

Overview

The IDT8T49N105I is a FemtoClock NG Universal Frequency Translator and Synthesizer featuring alarm and 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, High-Bandwidth Frequency Translator, and Low-Bandwidth Frequency Translator. Input references range from 8kHz to 710MHz, or 16MHz to 40MHz for crystal inputs. It provides a single differential output pair (Q, nQ) programmable as LVPECL or LVDS. Power supplies operate at 2.5V or 3.3V, and the component functions within an ambient temperature range of -40°C to 85°C.

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
Integrated alarm outputs for LOCK_IND, HOLDOVER, CLK_BAD, and XTAL_BAD

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 required factory-programmed configurations are specified during the ordering process, as these settings are burned into One-Time Programmable memory.

Selection Notes

Select the appropriate supply voltage configuration (3.3V or 2.5V) for VCC, VCCA, and VCCO based on system power rails. Ensure the desired output frequency falls within the supported divider ranges defined in Table 3. Use the provided configuration software to determine optimal register settings for loop bandwidth and feedback dividers.

Part Context

This component belongs to the FemtoClock NG family of Universal Frequency Translators. It utilizes fourth-generation PLL technology to provide low phase noise performance. The device allows for flexible frequency synthesis and translation without strict integer relationships between input and output frequencies.

Replacement Considerations

Consult Renesas Electronics for current equivalent parts, as this component may be subject to discontinuation notices. Verify pin compatibility and electrical specifications before substituting with other models in the 8T49N series.
