VSP1900DBTRG4

Overview

The VSP1900DBTRG4 is an 8-channel vertical clock driver for CCD sensors with electric shutter support. It features five 3-state and three 2-state vertical transfer channels, supporting both 3-field and 2-field CCD operation. The device operates with a digital supply (VDD) of 2.7 V to 5.5 V, a negative supply (VL) of -5 V to -9 V, and a high voltage supply (VH) of 11.5 V to 15.5 V. It drives loads up to 1890 pF with series resistors ranging from 60 Ω to 240 Ω. Propagation delays range from 15 ns to 100 ns, and rise/fall times are typically 300 ns.

Feature Summary

• Supports both 3-field and 2-field CCD operation through configurable vertical transfer channels
• Integrates electric-shutter functionality alongside standard vertical transfer outputs
• Provides low power consumption and reduces system parts count by combining multiple driver functions

Applications

• Digital cameras
• Video cameras

Procurement Notes

Verify the DBTRG4 suffix indicates tape-and-reel packaging and RoHS compliance. Confirm the operating temperature range matches the specific revision, as some variants cover -25°C to 85°C while others may differ. Ensure the source document explicitly supports these attributes before procurement.

Selection Notes

Select this component when designing systems requiring integrated vertical clock driving for CCD imagers with electric shutter capabilities. It is suitable for applications needing low power consumption and reduced bill-of-materials complexity by consolidating multiple driver stages into a single package.

Part Context

The VSP1900 is part of Texas Instruments' specialized CCD driver family. It was originally developed under the Burr-Brown brand before integration into TI's portfolio. The device addresses the need for compact, efficient clock generation in portable imaging devices.
