Overview
The SN65LVDS19DRFRG4 is a high-frequency oscillator gain stage and buffer manufactured by Texas Instruments. It features a fully differential input and provides low-voltage PECL or LVDS outputs. The device operates on a single 2.5-V or 3.3-V supply voltage. Key electrical parameters include a typical intrinsic phase jitter of 0.12 ps at 1 GHz, propagation delay times ranging from 340 to 630 ps, and output transition times of 250 ps. It supports clock rates up to 1 GHz and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Supports fully differential inputs for noise immunity
- Provides low-voltage PECL or LVDS outputs
- Features extremely low intrinsic phase jitter
- Includes a voltage reference (VBB) for single-ended PECL input translation
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 against the latest Package Option Addendum to confirm package type, lead finish, and moisture sensitivity level. Ensure the component status matches current production requirements, as availability and manufacturing details are subject to change without notice.
Selection Notes
Select this component when a fully differential input is required for the oscillator gain stage application. Compare it with the SN65LVDS18 if a single-ended input configuration is sufficient for the design. Verify that the 2.5-V or 3.3-V supply capability aligns with the system power architecture.
Part Context
This part belongs to the SN65LVx18/19 family of high-frequency oscillator gain stages. It shares functional similarities with the SN65LVP19 but differs in its specific output swing characteristics and interface compatibility. The DRF package designation indicates a small-outline no-lead form factor suitable for space-constrained PCB layouts.
Replacement Considerations
The SN65LVDS18 serves as a direct alternative if a single-ended input is acceptable. For legacy replacements, verify pinout compatibility with older variants in the SN65LVDS series.
