SN65LVP19DRFR

Overview

The SN65LVP19DRFR is a high-frequency oscillator gain stage and buffer manufactured by Texas Instruments. It features a fully differential input and provides Low-Voltage PECL (LVPECL) outputs. The device supports clock rates up to 1 GHz with a typical intrinsic phase jitter of 0.12 ps. It operates on a single supply voltage ranging from 2.375 V to 3.6 V, consuming a typical supply current of 36 mA. The package is an 8-pin WSON (DRF) measuring 2 mm x 2 mm. Electrical characteristics include a propagation delay of 460 ps typical and output transition times of 250 ps maximum for LVPECL.

Feature Summary

• Supports fully differential inputs for noise immunity
• Provides low-voltage PECL outputs for high-speed signaling
• Includes a dedicated Q output for oscillator gain control
• Features low intrinsic phase jitter for precision timing

Applications

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

Procurement Notes

Verify the specific ordering suffix DRFR against the latest TI Package Option Addendum to confirm availability status and manufacturing lead times. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the part marking ES with the datasheet to validate authenticity before procurement.

Selection Notes

Select this component when a fully differential input is required alongside LVPECL outputs. It is suitable for applications needing precise clock distribution with minimal jitter. Compare it against the SN65LVDS19 if LVDS outputs are preferred instead of LVPECL. Verify that the 2-mm x 2-mm WSON package fits the PCB layout constraints.

Part Context

This device belongs to the SN65LVx19 family of oscillator gain stages. It shares the same functional block diagram as the SN65LVDS19 but differs in output voltage levels. The family is designed for 2.5-V or 3.3-V systems and includes variants with single-ended inputs like the SN65LVP18.

Replacement Considerations

SN65LVDS19DRFT serves as a direct functional substitute with identical pinout and differential input, differing only in LVDS output levels.
