Overview
The TLV990-21PFB is a single-chip CCD analog front-end designed for digital still and PC camera applications. It integrates a 10-bit, 21-MSPS A/D converter operating on a single 3-V supply. The device performs essential analog processing to maximize dynamic range and corrects various errors associated with CCD sensors. Typical power consumption is 150 mW, with a low-power mode reducing consumption to 2 mW. It is housed in a 48-TQFP package measuring 7x7 mm.
Feature Summary
- Integrates complete CCD signal processing and digitization functions on a single chip
- Includes 10-bit analog-to-digital conversion at speeds up to 21 MSPS
- Corrects sensor-related errors to maximize image dynamic range
- Operates on a single 3-V supply with dedicated low-power shutdown capability
Applications
- Digital still cameras
- PC cameras
- CCD-based imaging systems
Procurement Notes
Verify the exact ordering suffix matches the required package and temperature grade. Confirm that the component meets all electrical specifications for your specific CCD interface requirements. Ensure compatibility with your system's power supply voltage and clocking architecture before finalizing procurement.
Selection Notes
Select this component when a complete, integrated solution for CCD signal conditioning and digitization is required. It is suitable for applications prioritizing low power consumption and high dynamic range correction within a compact form factor. Consider the 48-TQFP footprint and thermal characteristics during PCB layout design.
Part Context
This part belongs to Texas Instruments' family of CCD analog front-end processors. It serves as a specialized interface between CCD image sensors and digital processing units, handling complex analog tasks that would otherwise require multiple discrete components.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify functional equivalence carefully if considering alternative vendors or newer generations from Texas Instruments.
