5T9310NLGI

Overview

The IDT5T9310 is a 2.5V LVDS 1:10 clock buffer from the Terabuffer II family, designed for industrial temperature ranges (-40°C to +85°C). It converts user-selectable differential inputs (HSTL, eHSTL, LVEPECL, LVPECL, CML, LVDS) or single-ended LVTTL into ten LVDS outputs. Key electrical parameters include guaranteed low skew (<25ps max), very low duty cycle distortion (<125ps max), and high-speed propagation delay (<1.75ns max). The device supports operation up to 1GHz, features selectable reference inputs controlled by SEL, and includes power-down mode functionality.

Feature Summary

• Guaranteed low skew < 25ps (max) and very low duty cycle distortion < 125ps (max)
• Selectable differential inputs to ten LVDS outputs with hot-insertable and over-voltage tolerant inputs
• Supports multiple input interfaces including HSTL, eHSTL, LVEPECL (2.5V), LVPECL (3.3V), CML, LVDS, and LVTTL
• Asynchronous output enable/disable control via G1/G2 pins and power-down mode via PD pin

Applications

• Clock distribution networks
• Fanout buffering for preceding drivers
• Interface translation from various logic families to LVDS

Procurement Notes

This component has been discontinued. The last time buy expired on January 27, 2015. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory sources. No new production units are manufactured.

Selection Notes

Select this part for applications requiring a 1:10 fanout from differential or single-ended inputs to LVDS outputs within an industrial temperature range. Ensure compatibility with 2.5V VDD supply and verify that the required input interface standards (e.g., HSTL, LVPECL) match the device's translator capabilities. Consider the VFQFPN package dimensions for PCB layout.

Part Context

The IDT5T9310 belongs to the Terabuffer II series of clock buffers manufactured by Integrated Device Technology (IDT), which was acquired by Renesas Electronics Corporation. It is part of a broader family of clock distribution ICs designed for high-speed digital systems requiring precise timing and low jitter performance.

Replacement Considerations

Due to discontinuation, substitute parts must be sourced from existing stock or alternative manufacturers. Potential replacements should offer similar 1:10 LVDS fanout, industrial temperature range, and compatible input/output voltage levels. Verify pin-to-pin compatibility if direct replacement is required.
