VSP1900DBTR

Overview

The VSP1900DBTR is a CCD vertical clock driver with electric-shutter support, designed for digital camera applications. It features eight vertical transfer channels supporting both three-field and two-field CCD operation. The device includes five 3-state drivers (V-Transfer) and four 2-state drivers (three V-Transfer, one E-Shutter). Operating voltages include VDD/VL at 2.7 V to 5.5 V / -5 V to -9 V, and VH at 11.5 V to 15.5 V. DC power consumption is typically 5.3 mW, with operating supply current of 1 mA. Propagation delays range from 15 ns to 100 ns depending on the transition path.

Feature Summary

• Supports both three-field and two-field CCD architectures via configurable vertical transfer channels
• Integrates electric-shutter functionality alongside standard vertical transfer clocking
• Provides multi-level drive capability (VH, VM, VL) for direct CCD interface without external level shifters
• Reduces system component count by consolidating multiple driver functions into a single package

Applications

• Digital cameras
• Video cameras

Procurement Notes

Verify the specific ordering suffix DBTR corresponds to tape-and-reel packaging when sourcing. Confirm that the design accommodates the required negative supply voltage (VL) and high-voltage supply (VH) rails. Ensure input signals are compatible with the specified logic levels relative to DVDD. Review absolute maximum ratings to prevent damage during power sequencing or fault conditions.

Selection Notes

Select this component when designing systems requiring integrated vertical clock driving for CCD sensors with electric shutter capabilities. It is suitable for applications needing reduced part counts and low power consumption. Verify compatibility with the target CCD's capacitance loading requirements, which range up to 1890 pF. Consider the 30-pin TSSOP package constraints for PCB layout.

Part Context

The VSP1900 belongs to Texas Instruments' family of CCD vertical drivers. It is specifically engineered to handle the timing and voltage requirements of CCD image sensors in portable imaging devices. The device simplifies the interface between the timing generator and the CCD array by providing dedicated outputs for substrate, vertical transfer, and readout clocks.
