SN65LVP18DRFT

Overview

The SN65LVP18DRFT is a high-frequency oscillator gain stage and buffer manufactured by Texas Instruments. It operates on a single 2.5-V or 3.3-V supply voltage and accepts low-voltage PECL single-ended inputs. The device provides differential LVPECL outputs with a typical intrinsic phase jitter of 0.12 ps at 1 GHz. Key electrical parameters include a propagation delay time ranging from 340 ps to 630 ps, output transition times between 190 ps and 300 ps, and a supply current of 36 mA. It supports clock rates up to 1 GHz and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides clock signal amplification for high-frequency oscillator applications
• Features low-voltage PECL input and LVPECL differential outputs
• Includes a Gain Control (GC) pin for adjusting Q output amplitude
• Offers PECL-to-LVDS translation capabilities

Applications

• Clock signal amplification in high-speed digital systems
• Oscillator gain stages for frequency synthesis
• LVPECL to LVDS level translation interfaces

Procurement Notes

Verify the specific ordering suffix DRFT to confirm the WSON-8 package and 250-unit small tape-and-reel carrier quantity. Confirm RoHS compliance and NIPDAU lead finish status against the latest Package Option Addendum. Ensure the component matches the EP part marking for accurate identification during assembly.

Selection Notes

Select this component when a single-ended low-voltage PECL input must be converted to a differential LVPECL output. The inclusion of the GC pin allows for precise control over the Q output voltage swing. Verify that the system power supply aligns with the 2.5-V or 3.3-V recommended operating conditions.

Part Context

This device belongs to the SN65LVx18 family of oscillator gain stages. It is functionally similar to the SN65LVDS18 but specifically designed for low-voltage PECL inputs. The DRFT suffix indicates a 250-unit reel packaging format in a WSON-8 footprint, distinguishing it from bulk tube options.

Replacement Considerations

The SN65LVDS18DRFT serves as a direct functional substitute within the same family, differing primarily in input type compatibility.
