SN65LVP19DRFRG4

Overview

The SN65LVP19DRFRG4 is a high-frequency oscillator gain stage and buffer manufactured by Texas Instruments. It features fully differential inputs and low-voltage PECL outputs, supporting clock rates up to 1 GHz. The device operates on a single 2.5-V or 3.3-V supply with a typical supply current of 36 mA. It provides a voltage reference (VBB) typically 1.35 V below VCC for input signal reception. Key electrical parameters include a propagation delay of 460 ps typical, pulse skew of 80 ps at 3.3 V, and intrinsic phase jitter of 0.12 ps at 1 GHz. The component is housed in an 8-pin WSON package and is characterized for operation from -40°C to +85°C.

Feature Summary

• Supports fully differential inputs and low-voltage PECL outputs for high-speed clock distribution.
• Provides clock signal amplification with minimal intrinsic phase jitter for precise timing applications.
• Integrates a voltage reference generator to facilitate single-ended PECL input signal reception.

Applications

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

Procurement Notes

Verify the specific ordering suffix DRFRG4 against the latest Texas Instruments Package Option Addendum to confirm active production status and material specifications. Ensure compatibility with the required WSON-8 footprint and reflow temperature profiles during procurement planning.

Selection Notes

Select this component when fully differential inputs are required alongside low-voltage PECL outputs. It is suitable for designs needing clock amplification with low jitter characteristics. Verify that the system power supply supports both 2.5-V and 3.3-V operations as specified in the recommended operating conditions.

Part Context

This part belongs to the SN65LVx19 family, which includes variants like SN65LVDS19. Unlike the SN65LVDS19 which offers LVDS outputs, the SN65LVP19 specifically provides low-voltage PECL outputs. Both share the same differential input architecture and are designed for high-frequency oscillator gain stage applications within the same thermal and electrical envelope.
