Overview
The CS4955-CQZR is a digital video encoder manufactured by Cirrus Logic, designed for NTSC and PAL signal processing. It operates within an operating supply voltage range of 3.15 V to 3.45 V or 4.75 V to 5.25 V. The device draws an operating supply current of 70 mA or 100 mA depending on the voltage configuration. It is housed in a 48-TQFP package with dimensions of 7x7 mm. This component functions as a dedicated encoder for converting digital video signals into standard analog formats.
Feature Summary
- Supports NTSC and PAL digital video encoding standards
- Operates at dual voltage ranges: 3.15-3.45 V and 4.75-5.25 V
- Integrated 48-pin TQFP surface-mount packaging
Applications
- NTSC/PAL digital video encoding systems
- Consumer electronics video output stages
- Embedded video processing modules
Procurement Notes
Verify component authenticity through authorized channels due to potential availability constraints. Confirm voltage specifications match target system requirements (3.15-3.45 V or 4.75-5.25 V). Ensure PCB layout accommodates the 48-TQFP 7x7 mm footprint. Check for recent product change notifications regarding manufacturing updates.
Selection Notes
Select this component when NTSC or PAL encoding is required within a compact form factor. Consider power consumption levels of 70 mA or 100 mA during design phase. Validate compatibility with existing digital video interfaces. Ensure thermal management suits the TQFP package type for the intended application environment.
Part Context
The CS4955-CQZR belongs to Cirrus Logic's family of video encoders. It complements other Cirrus Logic components like the CS4954-CQZR. These devices are typically used in mixed-signal applications requiring reliable analog video generation from digital sources. The series supports various consumer and industrial video standards.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify if the CS4954-CQZR serves as a functional alternative based on specific pinout and feature requirements.
