SN65LVDS19DRFR

Overview

The SN65LVDS19DRFR 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 within the -40°C to +85°C temperature range. The device features fully differential LVDS inputs (A, B) and provides two low-voltage PECL or LVDS outputs (Y, Z). It supports clock rates up to 1 GHz with typical intrinsic phase jitter of 0.12 ps at 1 GHz. Propagation delay ranges from 460 ps to 630 ps, while output transition times are typically 250 ps for LVDS and 300 ps for LVPECL. The component is housed in an 8-pin WSON package measuring 2 mm x 2 mm.

Feature Summary

• Supports fully differential LVDS input signals for robust noise immunity
• Provides configurable low-voltage PECL or LVDS outputs for system flexibility
• Features extremely low intrinsic phase jitter suitable for high-speed clocking
• Includes integrated voltage reference (VBB) for single-ended signal reception

Applications

• High-speed clock distribution networks
• Oscillator gain stages and buffering
• PECL-to-LVDS translation interfaces
• Clock signal amplification in data communication systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm active production status and material specifications. Ensure the DRF package designation matches the required 2-mm x 2-mm WSON footprint for PCB layout compatibility. Confirm RoHS compliance and lead finish details prior to final procurement authorization.

Selection Notes

Select this component when differential LVDS input is required alongside low-voltage PECL or LVDS outputs. It is appropriate for applications demanding minimal phase jitter and propagation delay under 630 ps. Verify that the system power supply aligns with the 2.5-V or 3.3-V operating range and that the thermal dissipation requirements fit the small-outline no-lead package constraints.

Part Context

This device belongs to the SN65LVx19 family, which includes variants like SN65LVP19. Unlike the SN65LVDS18, it utilizes fully differential inputs rather than single-ended ones. It serves as a specialized interface solution for converting and amplifying high-frequency clock signals between different logic families in complex electronic architectures.
