TDA9955HL/17/C1,55

ADCs/DACs - Special Purpose Overview

The TDA9955HL is a triple 8-bit analog-to-digital video converter designed for high-definition television applications. It converts RGB or YUV analog signals into digital formats with sampling rates up to 170 MHz. The device supports resolutions from VGA (640x480p) to HDTV (1920x1080p). Key electrical parameters include an amplifier bandwidth of 100 MHz, I2C-bus bit rate up to 400 kbit/s, and power supplies of 1.8 V and 3.3 V. It features three independent ADCs, integrated sync slicers, and programmable gain control.

ADCs/DACs - Special Purpose Procurement Notes

Verify the package type LQFP100 (SOT407-1) matches design requirements. Confirm supply voltages are strictly limited to 1.8 V and 3.3 V domains. Ensure I2C bus timing adheres to the 400 kbit/s maximum specification. Check pin A0 configuration for correct slave address selection.

ADCs/DACs - Special Purpose Selection Notes

Select this component when interfacing analog video sources requiring digitization at resolutions up to 1080p. The device accommodates both progressive and interlaced inputs. Consider the 100 MHz amplifier bandwidth and 170 MHz ADC speed for signal integrity. Verify compatibility with downstream media processors accepting LV-TTL outputs.

ADCs/DACs - Special Purpose Part Context

The TDA9955HL belongs to NXP Semiconductors' video converter portfolio. It serves as a front-end interface between analog video sources and digital processing units. The device integrates synchronization detection, color space conversion, and formatting functions into a single LQFP100 package.
