5T9306NLGI8

Overview

The 5T9306NLGI8 is a 2.5V LVDS 1:6 clock buffer from the Terabuffer II series, manufactured by Renesas Electronics (formerly IDT). It converts user-selectable differential inputs to six LVDS outputs, supporting interfaces such as HSTL, EHVSTL, LVEPECL (2.5V), LVPECL (3.3V), CML, and LVDS. Key electrical parameters include guaranteed low skew of less than 25ps maximum, very low duty cycle distortion under 125ps maximum, and high-speed propagation delay under 1.75ns maximum. The device operates up to 1GHz with additive phase jitter typically at 0.159ps RMS @ 125MHz.

Feature Summary

• Converts multiple input standards (HSTL, LVPECL, CML, LVDS) to six LVDS outputs
• Guaranteed low skew < 25ps max and duty cycle distortion < 125ps max
• Supports operation up to 1GHz with typical additive phase jitter of 0.159ps RMS @ 125MHz
• Features selectable inputs, hot-insertable over-voltage tolerant inputs, and power-down mode

Applications

• Clock distribution networks requiring fanout from differential input to LVDS loads
• Translation from differential HSTL, EHVSTL, LVEPECL, LVPECL, CML, or LVDS inputs to LVDS outputs
• Systems requiring redundant input capability for asynchronous change-over between primary and secondary clock sources

Procurement Notes

The 5T9306NLGI8 is listed as End-of-Life (EOL) by the manufacturer. Mouser currently does not supply this part number in the specified region. Availability may be limited to factory special orders or existing stock. Verification of current lifecycle status and substitute availability is required before procurement planning.

Selection Notes

Select the 5T9306NLGI8 when a 2.5V LVDS output buffer is needed with low skew and jitter specifications. It supports input translation from various single-ended and differential logic families including 3.3V/2.5V LVTTL, HSTL, and LVPECL. The VFQFPN-28 package is suitable for space-constrained designs. Ensure compatibility with the 2.5V VDD supply requirement.

Part Context

This component belongs to the 5T93GL06 series of clock buffers. It is functionally related to the 8R9306NLGI8, which shares similar LVDS buffering capabilities but may differ in specific interface support or packaging details. The device was originally produced by Integrated Device Technology (IDT) before its acquisition by Renesas Electronics.

Replacement Considerations

The 8SLVD1208NBGI8 is identified as a possible replacement for the 5T9306NLGI8. Engineers should verify pinout compatibility and electrical parameter alignment against the original datasheet requirements before substitution.
